Design Considerations:
– Contec Fence Panel shall be designed in order to comply with safety and serviceability requirements as specified
by ACI 318-95 and following guidelines of ACI 523.2/R-96.
– Wind speed can be up to 80 mph for a 2” thick Contec Fence Panel and up to 100 mph for a 3” thick Contec
Fence Panel.
– Nominal heights for Contec Fence System should be 6 ft and maximum 8 ft.
– Contec Fence System requires post with grooves to insert Contec Fence Panels. The minimum depth of groove
should be 1 1/2”.
– Post must be designed according to Local Building Code (see Post for Contec Fence System).
– Posts, postcaps and concrete bases are not supplied by Texas Contec.
– Backer rod and caulking must be applied between the post groove and the Contec Fence Panel.

Installation Guide
Before Installation of Contec Fence
– Check fence layout and design. Decide, according
to terrain slopes, if fence will be stepped following
the contours of land (see Fig. 3).
– Check if material quantity (Contec Fence panels,
posts and post caps) is correct (see Fig. 4).
– Contact utility companies to insure that no
underground utilities will be affected with fence
construction.
– Always follow on-site safety measures during
construction.

Installation of the Contec Fence
1. Marking of Contec Fence
Check for property marks. When property marks are
not visible, you may call a surveyor. Mark location of
the fence according to property marks.
When fence is to be located on a hillside with steep
slopes or very irregular terrain, surveying equipment
might be needed.
2. Placing posts
Identify level difference on terrain and determine the
way that this will be compensated (stepped fence, etc.).
Fig. 4: Check quantity of Contec Fence panels and posts.
Posts must be plumbed (aligned vertically), and located
exactly in-line.
Concrete base:
A concrete base should be installed before placing
Fence panels. Drainage conditions should be assessed.
Leave drainage paths if required.
Variable*
Setting the posts:
Sink posts into the ground and set them in concrete.
Once post is in the hole, concrete should be compacted
using a tamper bar. Level and brace temporarily post
while concrete sets. Posts must have 1 1/2” height over
fence to assure proper installation of postcaps.

3. Contec Thin Bed Mortar preparation
Contec thin bed mortar is prepared in a plastic bucket,
adding water and mortar from the bag (see instructions
on the bag) and mixed with a stirrer in a power drill.
Use brush to clean the joint surface before mortar
application.
4. Contec Fence Panel installation
a) While two people hold the panel on its sides, a third
person helps, lifting it to slide it onto post grooves.
b) When panel is inserted into posts, two people keep
sliding the panel, holding it from its upper edge.
c) Once panel is in place, Contec Thin Bed mortar is
applied on joint before installing second panel using
a dull (large tip).
d) Wedge the panel temporarily with acrylic or wood
strips to adjust it into position (according to fence
design).
e) Repeat procedure for subsequent rows of Contec
Fence Panel. Care should be taken that panel joints
show the same height throughout the fence.
f) Once all panels of one section have been placed,
use
dull (small tip) to place mortar on joints to make
the appearence uniform.
g) Place bits of backer rod as wedges into joints
between posts and panels and remove the acrylic
strips. Then apply mortar or stucco to cover wedges.

5. Cutting on site of Contec Fence Panels
If there is the need for cutting Contec Fence Panels
on-site, follow the procedure shown below:
a) Prepare a flat surface for site cutting, using saw
horses.
b) Check for dimensions of cuts to be performed. Along
its length, panel can be cut in half (1 ft wide) at most.
c) Proceed with panel cutting.
d) Place anticorrosive paint at reinforcing bars tips.

6. Post caps
Post caps are placed on top of posts (see posts for
Contec Fence System).
7. Gates, ornaments and other fixtures
Gate installation must be made between gate posts.
Gate posts have special preparations to attach gates.
Fixtures like lamps, signs, etc. should be placed
preferably over posts. For placing fixtures over Contec
Fences, call Texas Contec for technical support.

8. Surface patching
Use Contec Repair Mortar to patch chips, breaks and
other imperfections on the surface of the Contec Fence
Panels.
Contec Repair Mortar is prepared in a plastic bucket,
adding water and mortar from the bag (see instructions
on the bag) and mixed with a stirrer in a power drill or
by manual means (depending of quantity to be used).
It is applied using a spatula.
9. Finishes
Although Contec AAC has a very low water penetration
rate, as with any concrete material it is recommended
to apply a finish coat consisting of color paint or acrylic
based render. Stucco, textured and other types of
renders are available through Contec.

Posts for Contec Fence
System
General considerations
Posts are used to provide support for Contec Fences
and must be capable of withstand wind loads applied
upon them; while satisfying local, regional and national
codes, such as Standard Building Code, Uniform
Building Code, etc.
Use design methods, in accordance with nationally
recognized organizations (American Concrete Institute,
ACI; American Society of Civil Engineers, ASCE; and
others), must be used.
Post caps
Contec Fence panel
Concrete posts or steel posts can be used for Contec
Fence System. Fig. 12 shows typical concrete post
sections.
Post caps
Used as a decorative element over posts (see Fig. 13).
The post cap should be fixed or glued, as determined
by the post material.

Note: For more technical information about posts and
bases, call Texas Contec.
