Editor’s Note
Comment: Troubled Times
Some may think the waterproofing
industry isn’t changing much. They’re
wrong.
The waterproofing industry—and
the construction industry as a whole—
is in the middle of an unprecedented
period of change. Within the last 18
months, half a dozen major factors have
combined to create a “perfect storm.”
Companies and contractors that do not
adapt to these new conditions will be
forced aside. Here’s just a few:
Economy:
The
construction
industry is in the middle of its worst
slowdown
ever.
Residential
housing starts are
lower than they’ve
been in 20 years,
and the drop was
as sudden as it
was steep. (The decline from 2005 to
2008 is more than 70%.) Commercial
construction, which usually lags behind
residential, has slowed dramatically as
credit has dried up.
While conditions have stabilized,
they’re not expected to improve
dramatically for at least two more years.
Businesses must learn to thrive in the
new reality.
Sustainability: Simply put, the
green building movement will change the
way this industry builds. From solvents
to sitework and everything in between,
waterproofers will need to adapt. “Green
building” practices are already mandated
by various agencies, and they’re rapidly
being incorporated into model building
codes.
Legal
Environment:
Recent
natural disasters—hurricanes on the
Gulf Coast, flooding in the Midwest—
have spotlighted the need for quality
waterproofing. But these disasters have
also
created
hundreds
of
lawsuits
and
new regulations.
Everything from
sump
pump
wiring to mold
remediation
is getting reby Clark Ricks
examined. Laws
affecting employee pay, benefits, safety
regulations, tax rates, and insurance are
also constantly changing.
New Materials: Today’s cutting-edge
products,
like
silane sealants,
urethane grout
compounds,
and carbon-fiber
repair kits make
waterproofing
work faster, easier, and more effective.
If you don’t know about new products,
chances are that your competition will—
and they’ll get the job.
New Technology: Sticking with
“yesterday’s technology” may make your
business “yesterday’s waterproofer.” A
solid company website has moved from
luxury to necessity. Customer databases
and employee cell phones are “standard
operating procedure.”
I believe that great change is always
accompanied by great opportunity. By
staying on top of all of these issues, a
waterproofing company can become
even more successful than he was a few
years ago.
That’s where this magazine comes
in. We want to help you navigate these
troubled times. Let me know what more
we can do to help.

WATERPROOF! News
Housing Begins Recovery
U.S. housing starts unexpectedly
snapped the longest streak of declines
in 18 years in February, rising 22% from
January. The jump was influenced by
warmer weather and an 82% surge in
starts on condominiums, apartments
and townhouses that’s unlikely to be
sustained, analysts said.
Building permits, a sign of future
construction, at a lower rate, indicating
construction may again slow. Total home
construction for this year is expected to
be about 450,000 homes.
Developers are still contending
with record foreclosures that depress
prices and profits, and the glut of
unsold properties on the market means
the housing industry’s recession will
probably continue for some time.
While economists say these numbers
indicate the worst of the contraction
may have passed, don’t expect a rapid
rebound.
“We expect demand for all homes,
both new and existing, to remain far
below normalized levels,” says one
economist.

Guarantee
Vancouver-based
Kryton
International Inc. now offers a
performance warranty for structures
using
their
unique
crystalline
waterproofing product.
The Krystol Assurance Program
guarantees that areas of a structure
waterproofed by Kryton will remain
watertight for 10 years. It also provides
enhanced quality control and project
support through consistent onsite
supervision, mix design consultation,
jointing design review and training for
applicators.
“Water intrusion and the damage it
causes is the number one contributor to
a concrete repair industry worth billions
of dollars every year,” says Kari Yuers,
CEO of Kryton.
“Concrete waterproofing.. is one of
an owner’s most strategic investments
and this program ensures that investment
pays off with long term peace of mind.”
The program is distinct from
Kryton’s standard warranty, which
guarantees that every product is free
from manufacturer defects.
Therma-Stor Adds Staff
Therma-Stor Products, manufacturer of several lines of dehumidifiers
and moisture control products, has
added two senior staff members.
Steve Reppen was recently hired as
the National Sales Manager for UltraAire Products. Reppen previously
held national sales leader and general
management roles at Milgard Windows

products that promote moisture control
for the optimization of Indoor Air
Quality and Asset Protection.
SWRI Launches Two New
Validation Programs
In addition to their product
validation program,
the Sealant,
Waterproofing & Restoration Institute
(SWRI) is now validating contractors.
The overall objective for both the
Training Validation and Contractor
Validation programs is to ensure that
owners and designers receive the highest
standards of workmanship.
The Training Validation Program
analyzes the contractor’s quality
assurance program, and ensures
applicators know how to properly install
a given product. Specific technical
content has been outlined and is required
for review.
In the Contractor Validation
Program, the Contractor will be
evaluated on similar project experience,
key management personnel, financial
stability, safety, training, insurance
and other marketplace benchmarks.
Contractors will be awarded a
Recognition Level (i.e. Platinum, Gold,
Silver, Bronze) as their validation seal
based upon results of their application. According to Erin Neid, a marketing
director at SWRI, the ultimate goal of
both programs is to assist the end user
in selecting competent firms to maintain
their structures.
Nichols comes to Bilco with more
than 19 years of experience in the
building products industry.
“Kent Nichols’ sales, marketing
and international business development
skills, combined with his expertise in the
export markets of the Middle East, Latin
America, Canada and the Caribbean,
will play a key role in our international
expansion plans,” said Dominic
DeConciliis, Bilco’s vice presicent of sales
and marketing.
Regional Waterproofing

membership
to
waterproofing
contractors across the country.
They kicked off the program in
Chicago on May 22-23, 2009. The
two-day event had a full schedule of
educational seminars covering topics
from indoor air quality to internet
marketing and the basement repair
industry. The first day focused on how
basement repair contractors could help
real estate agents sell houses faster. This
seminar also provided an opportunity to
meet and network with local real estate
agents and inspectors.
The second day catered to
contractors with topics such as how to
become more profitable.
The event’s primary sponsor
was Metropolitan Industries Inc., in
Romeoville, Ill. which offered a tour of its
pump manufacturing plant. The 100,000
sq. ft. facility makes sump pumps and
other dewatering devices. The tour also
included the newly opened Energy and
Water Independent Metro-Green house
nearby. This 480 sq. ft. green home is
equipped with solar panels, a windmill,
a full rain harvesting system, solarpowered radiant heated floors, and a
solar-powered well pump.

International Leak Detection (ILD®)
is the worldwide leader of integrity testing technology.
Why do this...
Historically, flood testing was utilized to confirm that waterproofing and
roofing membranes were watertight. However, flood testing has many
drawbacks, especially when comparing it to the latest EFVM® testing
method only used by ILD®’s trained and certified technicians.
EFVM® vs
When this can be done!
Flood Testing
ILD® technicians use EFVM® testing to pinpoint exact
breaches in membranes without relying on wet spots within
the insulation or visual confirmation of a breach.
Only proves the capability of a waterproofing membrane to HOLD water; it cannot locate breaches or
verify the absence of any breaches.
EFVM® requires as little as a spray of water or existing
water within the overburden to test waterproofing.
May actually cause more damage with membrane
breaches from the required amount of flood water.
EFVM®’s technology can be used on flat, sloped and vertical surfaces.
Sloped or vertical surfaces cannot be flood tested.
Testing can occur after all work is completed and overburden is installed.
Expensive and time-consuming, often causing delays
in overburden installation and roof completion.
Any breach allowing even minute amounts of water will
conduct electricity to complete a circuit, measurable by
the ILD® technician.
Pinholes and minor seam voids escape flood testing
detection which could subsequently cause mold or
structural decay.
The contractor can repair the defects found and have them
retested the same day.
Water infiltration damage from flood testing often
restrains retesting.
EFVM®’s non-destructive method reads through all typical
water-permeable overburden mediums such as soil, sand,
crushed stone, pavers, asphalt, and un-reinforced concrete
Garden roofs prohibit flood testing.

SOLAR ROOFS
Challenges and Waterproofing Solutions

ooftop solar panels are becoming
increasingly popular.
Rising
energy
prices,
combined
with concerns about pollution, global
warming, and sustainable building
practices have made the technology
more viable than ever before.
“As any technology expands, price
comes down,” says Patrick Howard, CEO
of the Howard Company,
a supplier and consultant
to both the waterproofing
and solar panel market.
“This is especially true of
photovoltaics, and now there are all the
green energy incentives coming into
place as well.”
In San Diego, for example, solar
integrated roofing systems have been
installed, or installation is in progress,
on 14 city schools, with more scheduled
in the coming two years. Benefits
The school system expects to save
millions of dollars in energy costs over
the next 20 years, in addition to helping
the state make progress toward the
goal of generating 20% of its electricity
facility to install solar panels and sell the
electricity back to the users.
Photovoltaic roofs also help
buildings qualify for certification with
green building programs. Under the
U.S. Green Building Council’s current
LEED criteria, a building can gain up to
3 points by using solar energy.
Most solar roofs, especially in the
commercial sector, are more
properly called “photovoltaic
panels.” These systems convert
light into electrical energy
using thin wafers of silicon.
(The other type of panel is basically a
solar hot water heater.)
For rooftop waterproofers, rooftop
panels create additional challenges, as the
mechanical attachments, cables, pipes,
and other penetrations need special

with renewable sources by 2017.
Howard cites cases where Southern
California Edison has approached large
building owners to essentially rent their
roofs. In one instance, they leased back
roof space on a 100,000 sq. ft. Montana
attention.
Recently though, several
new technologies promise to radically
simplify installation, and make solar
energy generation more cost-effective
than ever before.
Built-In Panels

Frito-Lay, the snack food maker,
installed a photovoltaic roof on its
65,000 sq. ft. facility near Los Angeles,
California.
The Frito-Lay Distribution Facility in
Los Angeles uses a new technology
that combines a waterproofing
membrane and solar panels into a
single flexible product.
The decision was partially driven
by the chronic power outages that
plagued the state in 2000 and early 2001.
Electrical blackouts and record high
energy bills made business difficult. The
company also has a reputation for being
environmentally conscious. So when
the distribution warehouse needed to
replace the existing built-up roof with
a durable, long-lasting alternative, they
chose to include solar panels.
“The LADWP [Los Angeles
Department of Water and Power] was
offering a substantial incentive to install
solar photovoltaic roof systems,” says
Chris McKenna, electricity manager
at Frito-Lay. “That made the project
economical for us.”
The project was the first to use
a new product from Solar Integrated
Technologies (SIT) called SR-2001.
The design combines an impermeable
waterproofing
membrane
with
photovoltaic cells in a single sheet.
SR-2001 uses a 60-mil single-ply
thermoplastic membrane from Sarnafil
as a base, then laminates a dozen flexible,
thin, lightweight photovoltaic modules
onto it.
Peter Chaitkin, account executive
at Solar Integrated Technologies, says
they chose the membrane due to its
performance history and heat-welded
seams. “It provides the owner with a
durable roof that lasts for decades,” he
says.
The 10-ft-by-40-ft photovoltaic
roofing panels are then hot-air
welded to an installed Sika Sarnafil
EnergySmart Roof. Each panel generates
approximately 1,500 watts. The result is a
photovoltaic roofing system that protects
the building interior from the elements
while generating power for its electricity
needs.
Southern California Roofing got the
nod to install the system.
First, we arranged the photovoltaic
modules according to the customer’s
request for kilowatt power,” said Chuck
Point, project manager at Southern
California Roofing. Since Frito-Lay
wanted a 100 kilowatt system (100,000
watts), the roof needed 70 of the 10x 40
panels. He says the actual installation
went smoothly, noting that the company
has installed Sarnafil products for more
than 20 years and the workers are very
familiar with it.
The outer face of the membrane
is white, which increases the panels’
efficiency.
“The membrane’s reflectivity allows
the flexible photovoltaic panels to absorb
more of the sun’s rays in less-thanoptimum conditions,” said Chaitkin.
“The EnergySmart Roof membrane
reflects the sun’s rays, reduces heat
absorption into the building, decreases
cooling costs, and actually increases the
productivity of the solar panels.”
Energy from the panels is collected
in wires and routed to inverters that
convert the DC power into alternating
current that Frito-Lay can use to run
computers, lights, air conditioners and
other equipment.

clean energy annually, enough electricity
to power 28 homes.
“The system works so well that
during some periods of the day, we are
producing more power than we need,”
said McKenna. “When that happens, the
extra power gets fed back into the utility
grid.”
The company has since installed
another system on its Sylmar, California
distribution center roof, and anticipates
additional installations in the future.

Metal Roofing Options
Built-in photovaltaics are becoming
quite common, and are available
for many different roofing systems,
including metal roofing.
SolarPower Restoration Systems
markets SolarSeal PV, a metal roof
system that
combines photovoltaic
technology with high-performance
elastomeric coatings.
According to
Michael Gunn, company vice-president,
it creates a leak-proof, energy-generating
roof over any standing seam or R-panel
industrial metal roofs.
“Commercial buildings with metal
roofs use industrial R-panel roof panels
or the newer architectural standingseam roof panels,” he says. “Both R-type
roof panels and the architectural snap
seam metal panels are waterproofed
using elastomeric coatings designed to
work with each specific type of metal
roof surface.”
Once the roofs are waterproofed,
solar modules are applied to the
coated metal surface. Materials such as
synthetic textiles, polymers, insulation
or radiant water modules are used to
bridge irregular metal panel surfaces and
exposed fasteners. Photovoltaic modules
are bonded to the components and
flashed and sealed, creating a continuous,
seamless, waterproofed roof surface.
“The SolarSeal Roof System is a
long-term solar waterproofing solution
for metal roofs,” says Gunn. “They’re easy
to maintain and can be renewed without
affecting the photovoltaic system’s power
production.”
He adds that, like SR-2001, the white
elastomeric coating reduces metal roof
surface temperatures and lowers cooling
cost.

hether used as a drainage board, underslab
insulation, or in roofing systems, every waterproofer
deals with foam board.
“Rigid foam insulation works very well with many
waterproofing systems,” explains John Cambruzzi at Insulfoam.
“It’s a product that is well established and well known from a
performance standpoint.”
In recent years, some have said that rigid Expanded
Polystyrene (EPS) foam was obsolete for below-grade
16

applications, but Cambruzzi disagrees. “It has a long history of
excellent performance in both horizontal and vertical belowgrade applications,” he says.
The key is understanding the material, its strengths and
limitations, and ensuring that the waterproofing design takes
these traits into consideration.
Vertical Below-Grade

WATERPROOFING
EPS is use as a protection course or drainage layer on vertical
below-grade work. Dimple drain sheets, fiber mats, or inorganic
mineral wool are sometimes used instead, but Cambruzzi says
EPS has real merit.
“From a rigid foam standpoint, the advantage, with our
product, is the insulation value you’re getting,” he says. “If
you’re planning to insulate because you have working or living
space on the inside, EPS gives you an advantage that no other
product can.”
Dave Nichols, vice-president of marketing at Mar-Flex,
says rigid foam drain boards are popular for another reason as
well. He states, “Contractors use foam because it’s lightweight
and easy to install.”
It’s true that other materials require much more labor.
Foam boards are simply pressed against the newly waterproofed
wall, where the tackiness of the spray-applied membrane holds
it solidly in place until the wall is backfilled. Drain sheets, on the
other hand, require mechanical fasteners, transition strips, and
other components.
While Mar-Flex does sell rigid foam boards, Nichols insists
there are better options on the market.
“I’d rather have it than nothing, but there are better choices
in the waterproofing world,” he says, although he admits, “A
lot of times it’s the best answer for a foundation.” His major
objections are that the grooves in the drain board fill in, and that
foam compresses under the weight of the backfill.
Cambruzzi says current foam boards on the market have
resolved those concerns.
Spring 2009

"The biggest risk installers face
is that foam sheets will break and
chip before the concrete slab is
placed over them."
“Our product has a filter fabric on it that covers the
channels,” he says. “That keeps the sediment out of it. From
a long-term performance standpoint, we don’t have a problem
with those channels filling up with sediment.”
He also disagrees with claims that compression from
backfill pressure leads to a loss of R-Value. “Ground pressure has
a minimal impact on R-Value, and is not a big concern in terms
of long-term performance,” says Cambruzzi. “Our experience
indicates that the product compresses very little.” He adds that
Insulfoam can manipulate the density of the foam from as low
as 10 psi to as high as 60 psi. “If the specifier knows the load, we
can take expense out or add it in to meet job conditions.”
Both agree that a waterproof coating behind the drainage
layer is crucial. “The most important thing is protecting it from
moisture penetration,” says Nichols. “You need a good coating
18
WATERPROOF!
on the wall before you get a protection layer on that.”
Horizontal Below Grade
Another common area where waterproofers have to deal
with foam is when they are used in underslab applications. Like
vertical above-grade work, a membrane is used to eliminate
moisture coming through the slab, while the foam keeps the
concrete warm. This type of work is especially common with
in-floor hydronic heat or any time the slab itself has heating or
cooling elements within it.
Installation guidelines vary on whether the foam should
be installed on top of the moisture barrier, or beneath it (see
The Underslab Solution in the Winter 2009 issue for more
information), but the challenges are the same.
The biggest risk installers face is that foam sheets, often
only an inch thick, will break and chip before the concrete slab
is placed over them.
Sheets that are thick enough to avoid breakage cost more,
and provide negligible additional energy savings.
Luckily, there are good solutions on the market.
The most important step, regardless of the product installed,
is to ensure the subgrade is flat, level, and properly prepared.
Cambruzzi, at Insulfoam, says manufacturers can
manipulate the compressive strength of the foam to create a
more flexible product. “The higher the compressive strength of
the foam, the more rigid the product is, and the more susceptible
it is to breaking,” he states. “By taking some of the density out
of the product you’ll get a foam that’s more jobsite friendly.” He
notes that even a 25 psi foam provides resistance of 3,600 pounds
per sq. ft., plenty of resistance for most underslab applications.
His company also offers foam with a polymeric film on
both sides, which helps to keep the EPS from chipping and
shattering. If it does break, the film holds the pieces together so
the effect is negligible. “In a below slab-application, an unfaced
or unskinned product performs fine. But the film makes it more
jobsite durable, more moisture resistant, and less likely to be
damaged during handling and installation.
The plastic film on Insulfoam sheets does not serve as
waterproofing however.

For true waterproofing and insulation in a single product,
several companies offer underslab products that combine a
flexible EPS core with two layers of vapor and moisture resistant
materials.
Northwestern Ohio Foam Products markets the Barrier and
BarrierXT, both of which provide a flexible insulated underslab
barrier. The rolls are 60 feet long, so instead of having gaps
every 4 and 8 feet, there are just a few seams. The product has
a self-taping flange on one edge that makes these easy to seal.
“The biggest thing is installation cost,” says Wally
Radjenovic, president of NOFP. “Normally, the insulation and
the vapor barrier are discrete components, and it’s very time
consuming if you have to lay and tape two products. You’re
adding a lot of labor dollars to an already expensive product. By
combining them into a single product like the Barrier, it’s easier
to meet deadline, and you’re saving money, too.”
Of course, another advantage of a flexible core is that the
installer doesn’t have to be as exacting when installing the subbase, which saves on labor costs as well.
The flexible EPS foam in the standard Barrier is 3/8 inch
thick. The BarrierXT has ¾ inch. The moisture barrier is 3 mils
thick on both products.
Roofing
A third area where waterproofers often have to deal with
foam board is commercial roofing. Like underslab insulation,
the placement of the foam varies from job to job. On some roofs,
the foam is installed over the membrane; in other applications,
it is placed below it.
The major challenge in this area is that roofing membranes
often require heat and/or harsh solvents, both of which are
incompatible with foam.
“Foam plastic do not do well in the presence of solventbased adhesives,” says Cambruzzi. “In applications where these
solvents will come in contact with these products, the installer
or specifier needs to use a different insulation or have a plan
how to avoid contact, like using a slipsheet. Foam’s sensitivity
20
WATERPROOF!
to solvents is a drawback. It’s something that you would have to
recognize and address.”
Solvents are not only bad for foam, but they’re bad for the
environment and the installer’s health. Because of this, many
roofing suppliers are moving to more environmentally friendly
products; singly ply membranes, adhesive tapes, and heat
welded seams. So solvents are becoming less of an issue.
Long Term Performance
Another common concern is moisture resistance. While
foam is not as moisture resistant as, say, a dimple drain sheet,
it does outperform other insulation options, like rock wool or
open-cell foam. Cambruzzi points out that although EPS foam
will absorb some moisture from saturated soils, it readily gives
up that moisture when surroundings dry out. “Over a seasonal
or annual cycle, that foam will continue to perform, because it
readily gives up that moisture,” he states.
With the rising interest in green building, the sustainability
of expanded polystyrene is also a topic of interest. EPS is a
petroleum-derived product, and requires a significant amount
of energy to make and transport. But according to a recent
study published by the EPS Manufacturers’ Association
(EPSMA), the insulating value of the foam saves more than
100 times more energy than was used in its manufacture.
“EPS is environmentally friendly, 100% recyclable, containing
no HCFCs or formaldehyde and can contribute toward LEED
credit requirements,” the report states.
Some competing products have done a good job convincing
specifiers that EPS is not a good option,” says Cambruzzi,
“but EPS has a long history of excellent performance in both
horizontal and vertical below-grade applications. EPS has
been used in geofoam applications, going under exit ramps,
highways, and bridge approaches, and has performed just fine
in those harsh conditions.”
“When used with standard waterproofing products,
there are no real compatibility issues,” he continues. “They’re
operating and functioning independent of each other.”

Advances and Installation
I
t’s a nightmare every homeowner
dreads:
The basement flooded,
belongings soaked. Carpeting and
drywall ruined and waterlogged.
While
a
comprehensive
waterproofing and drainage system has
many components, sump pumps are
considered the most crucial. Unlike
the membranes, drainage sheets, and
perforated pipe, which usually last for
the life of the structure, sump pumps
need to be replaced every few years.
But waiting for failure isn’t an
option, as it would inevitably lead to the
nightmare described above.
Fortunately, new pump technologies
and proper installation can ensure that
this critical piece of the system is fail-safe
and affordable.
Components
All sump pump systems have the
same five components, although they
vary in size based on the amount of water
they are required to handle.
In the United States, components
are fairly standardized. For residential
applications, they consist of:
1. A plastic or metal sump liner, either
18 or 24 inches in diameter and 2 to
3 feet deep.
2. A pump, usually 1/3 or 1/2
horsepower and powered by either
at 12-volt DC battery or standard
120-volt AC current.
3. A discharge pipe, typically 1 ½ inch
PVC.
4. A check valve to ensure the water
in the discharge pipe doesn’t flow
backwards back into the sump;
5. A cover to keep vermin, pets, and
debris out of the sump.
Sizing
Pump Size: A properly sized pump
is critical. Too small and it won’t be
able to keep up with water flowing
into the sump. Too large and it creates
unnecessary expense. An oversized
pump will also “short-cycle,” turning on
and off in rapid succession, which leads
to premature pump failure. So getting
the right pump is an important first step
to ensuring basements stay dry.
“It’s important that your pump can
draw water out of the basin (or “sump

also increases the chances the sump will
overflow, so be careful.
Power Supply
Direct-Wired: Almost all sump
pumps run on standard 120 volt AC
current, but the pump must be supplied
with its own line from the breaker box.
It must also have a dedicated breaker. In
most areas, the power supply must be
installed by a licensed electrician unless
the installer is also the homeowner. As
always, check with local building codes
and ordinances.
Pumps are usually hard wired into
the electrical system, rather than plugged
into a conventional outlet.
Battery-Powered: Sump pumps
face their highest loads during

thunderstorms, when rainwater pours
into the sump pit from the foundation
drainage system.
Unfortunately,
thunderstorms can also disrupt a home’s
power supply, knocking the pump offline
at the time it is needed most. That’s why
"New pump technologies and
proper installation are a critical
piece of the system"
cheaper option may be to raise the height
of the pump switch, basically making the
sump deeper. This method, however,

pit”) faster than water flows into it,”
notes Duane Friend, at the University
of Illinois Extension Office. “Therefore,
the first thing you need to measure is
the amount of water that drains into the
basin during a high-flow period. During
a heavy rain, stick a ruler in the basin
and measure how many inches of water
flow into the basin in 60 seconds.”
With an 18-inch sump, each inch of
depth equals one gallon. In a 24-inchdiameter basin, each inch is roughly 2
gallons.
In a new construction situation,
approximate flow rates can be calculated
based on rainfall averages, soil type and
the size of a home’s footprint.
Once the volume of water that will
need to be removed has been calculated,
the installer will need to figure out the
“total dynamic head” of the discharge
pipe. This is the sum of the “static head”
(the height in feet between the pump
and the end of the discharge pipe) and
the “friction head.” Friction head is
calculated based on the length, diameter
and material of the discharge pipe, and
the number of turns involved. A table to
calculate friction head is available on the
www.waterproofmag.com website.
Knowing the maximum flow rate
figures, the total dynamic head pressure
involved, and the budget, the contractor
or designer can determine the best pump
for the application.
Basin Size: The size of the sump pit
is also important, as it plays a part in how
long the pump runs and how long it takes
to fill up. If the basin fills too quickly it
may be best to install a larger one.
If the basement is already finished, a

the first pump fails. In a few areas of the
country, where the sump pit only fills
occasionally, battery-operated pumps
are used as the primary.
Setting up a battery-powered
secondary pump involves purchasing
and installing the following components
in parallel with the others:
• A 12-volt DC sump pump matching
the flow and discharge requirements
of the primary pump.
• A 12-volt DC lead-acid battery.
A typical automobile battery is
adequate. Some use marine-grade
deep cycle batteries which are more
expensive, but lasts longer.
• A “trickle-charge” battery charger
to keep the lead acid battery fully
charged.
• A separate water level sensor, check
valve, and other components. The
discharge pipes usually connect
downstream of the check valves.
“One of the problems with most
backup sump systems is they are rarely
used so a component failure will not
be noticed and the system will fail to
operate when needed,” says Friend.
A few battery-powered pump
systems have an integral computer
that tests the system periodically and
sounds an alarm if something needs to
be replaced—like a “check engine” light

on a car.
Regardless, Friend recommends
that backup systems be tested monthly.
“A good time to test is just after a rain
storm,” he says. “Pull the plug on the
sump pump so the sump well fills and
verify the backup system activates and
empties the well.”
Water-Driven: Recently, a few
manufacturers have begun offering sump
pumps that use the home’s culinary water
supply to power the pump. The pressure
in the home’s main water line turns an
impellor, which drives the pump. These
devices eliminate the need for electricity
entirely. They do cost more than motordriven pumps, but because they don’t
need a back-up pump, they can be costeffective.
Regardless of the type of pump
installed, plan on also using a simple
battery-powered water alarm. The water
sensor is attached to the sump liner a few
inches below floor level and will sound
a shrill alarm if the water level rises that
high.
Pump Type
Regardless of the type of power
supply, sump pumps are generally
divided into two classifications, pedestal
and submersible.
Pedestal pumps are mounted above
Discharge Pipe
The discharge pipe should end as far
from the house as possible, to prevent the
water from finding it’s way back under

In decades past, the pipe was often
connected to the sanitary sewer system.
This practice is now outlawed as it can
overwhelm the water treatment facilities.
Be aware that if you are retrofitting an
older home, codes and ordinances may
require you to also reroute the discharge
line.

the pit, where it is more easily serviced,
but also more conspicuous. Submersible
pumps sit inside the sump—usually
near the bottom—and are completely
immersed in the water.
The decision is usually based on
whether the basement is finished, or
will be, as the submersible pump is less
obtrusive.
In commercial applications,
submersible pumps are most common,
as they funtion on a different principle.
Unlike pedestal pumps that “suck” water
up from the sump like soda thorugh a
straw, submersible pumps “push” water
up the pipe.
Because pedestal pumps sit above
floor level, they are usually hidden
from sight in finished basements. This
can be a purpose-built enclosure, as
shown in the before-and-after photos
above, or by building the sump in a
closet or furnace room.
Green Sealants at the Bottom of the World

P
rincess Elisabeth Station is not a typical construction
project. Built by a Belgian team to study the harsh
Antarctic environment, it was built in one of the
harshest and most remote regions of the planet. It was also
built with extremely demanding green building techniques.
When construction ended in February, it became the only
zero-emissions building on the continent—the first to operate
without releasing any greenhouse gases.
The 20 million euro ($26 million) science station is
completely energy self-sufficient, and uses micro-organisms to
re-use water up to five times. Power and hot water are made
possible by wind turbines on a nearby mountain and solar
panels mounted on the building.
The Antarctic research station is located in Dronning Maud
Land, thousands of miles south of the African coast.
Finding a long-lasting sealant that would perform in one
of the planet’s harshest climates, while still meeting the zeroemissions green building standard was one significant challenge
designers faced.
Scientists at Dow Corning said silicone sealants were up
to the challenge. Jean-Paul Hautekeer, European construction
director for Dow Corning explains, “Dow Corning silicones
are virtually unaffected by weather—rain, snow, humidity,
ozone, temperature variation or the sun’s damaging ultraviolet
rays—and can make building what we may think is impossible,
possible.”

The silicone sealant used at Princess Elisabeth research
station has a proven record in extreme environments. It’s similar
to the product used in the silicone rubber boots astronauts wore
when they walked on the moon’s surface, where temperatures
drop to -150°C.
The final phase of the station’s construction lasted a
little over 4 months, and research teams will begin living there
as soon as November 2009 to conduct climate change research.
Engineer’s Corner
Tips for Protecting Building Aesthetics
By Larry Carbary
Because the physical condition of a building can
change greatly over time from such external forces
as sun, wind and rain, choosing materials that will
maximize the life and appearance of the structure,
while minimizing the amount of damage is crucial.
This is especially true in selecting a sealant. Here are
some of the most common aesthetic issues to consider:
Dirt Pick-Up – Accumulation of dirt on a sealant’s
surface is particularly prevalent on construction sites
with high volumes of dust. The actual amount of
dirt pick-up will vary with exposure conditions, but
excessive pollutant contamination will result in lower
durability and weaker bond strength. To avoid this,
choose a sealant that can tolerate higher levels of
contamination. Chalking – As the substrate begins to degrade
and erode over time, the surface becomes more rough
and porous, which leads to a loss of surface gloss and
color. Chalking is most observed in organic sealants
that are initially black or brown, but later transform
into a light grey or beige. This does not occur with
silicone or acrylic sealants. Change of Color – Change in color can result
from factors both inherent and external to the sealant. Incompatibility of the sealant with other building
materials is a contributing factor. Materials with
high incompatibility levels include low molecular
weight polymers, antioxidants, or tar. A sealant that
is compatible with a variety of other substrates is
preferable. Surface Crazing – A variety of factors including
sunlight, environmental stress and ageing can cause
cracks in the sealant’s surface. This is especially
common with organic sealants. Generally, sealants
with higher polymer content are more durable and
have less crazing. Fluid Migration – Fluids can migrate from a
sealant to the substrate, creating a dark “wet” band
look around the joint of the sealant. The extent and
rate of fluid migration varies with the type of sealant.
Cheaper, less formulated sealants are the most prone
to staining and fluid migration. Other Environmental Factors – Oxygen,
ultraviolet radiation, climate/temperature, microbial
growth
and
other
environmentally-induced
mechanisms can contribute to the fatigue and stress
that degrades and lowers the overall bond strength of
the sealant. While aesthetic issues cannot be completely
avoided, they can be mitigated through prior
knowledge; selection of high-quality, highperformance building materials; and working with a
reputable manufacturer. Larry Carbary is a Construction Associate Industry

jobsite safety and productivity through moisture control
and air purification. For instance, paint and coatings dry
faster, allowing multiple applications in shorter time periods.
In addition, Quest equipment will create a safer, more
comfortable working environment while the technicians are on
the jobsite. With its robust construction, high performance,
and portability, Quest is the perfect complement to successfully
complete any waterproofing, construction, and painting-andcoating project.
Therma-Stor unveiled the Quest product line at World of
Concrete 2009, in Las Vegas. For more information, call (800)

Dow Water Repellant Sealant
Dow Corning, maker of a variety of silicone water repellents,
has added two new products to its lineup. Both are specifically
made to seal rock, stone, concrete, and similar materials.
The 6706W and 6707W Penetrating Stain Repellents are
water-based fluorosilane post-treatments that provide effective,
environmentally-sound water and oil repellency.
According to Shawn Kuch of Dow Corning’s building
materials protection group, substrates treated with the products
remain permeable to water vapor and retain their original
appearance with the additional benefits of reduced dirt pick-up
and easier cleaning.
“Environmental factors such as water, oil, stains, and
sunlight can have harmful effects on construction materials
by damaging surfaces, reducing aesthetic value, and increasing
maintenance costs,” said Kuch. “Dow Corning’s new family of
penetrating stain repellents provides durable, environmentally
sensitive protection to these materials without affecting their
appearance.”
The reason the products work so well on porous
construction materials like concrete, natural stone (such as
sandstone and limestone), pavers, mortar, and grout is due to
the small molecular size of the flourosilane, which allows it to
penetrate deeply and chemically bond to the substrates.
It creates a layer of protection that reduces water absorption
and the damage caused by freeze-thaw cycles.
The 6706W Penetrating Stain Repellent is a ready-to-use
product.
The 6707W product is a concentrate that can be diluted
with water. Both products are solvent-free and will not damage
glass, metal, wood, or most plastics.
Epoxy Paste for Crack Injection
Polybac#1003 from Polygem, Inc. is a fast-setting, lowodor epoxy paste that is specially formulated for sealing cracked
concrete prior to the injection of epoxy resin or polyurethane
grout.
Polybac#1003 is an easy-to-mix, two-part epoxy, which
gives the applicator up to 10 minutes of work time and will
be ready for injection in as little as 25 minutes. The thick nonsag paste will allow for vertical and overhead patching. It’s also
waterproof and will bond to damp surfaces, and will even cure
underwater.
Polybac#1003
is ideal for setting
injection
ports,
sealing crack surfaces,
setting anchor bolts,
repairing sea walls or
any other underwater
concrete repair, such
as aquarium and pool
repairs.
