ECOGRID - Bound Installation Manual copy

ECOGRID®
INSTALLATION MANUAL - RESIN BOUND STONE
WHY ECOGRID®?
Quick and easy to install (about 100 m2 per person per hour)
Lightweight (approx. 5 - 11 kg/m2 depending on type)
Low transport and handling costs
High load capacity (up to 800 t/m2 filled)
Safety locking system
Surface reinforcement with natural drainage
Extremely versatile thanks to additional components like
slope angles, curvepieces
Minimises maintenance
Non-slip and crackproof
Weatherproof and environmentally friendly
Resistant to frost and UV radiation
Easy to fit to borders or cut to shape
PREPARATIONS
How much loose aggregate will you need?
Depending on thickness of grid being used, approx. quantity
required for levelling and filling the grids with 10mm shingle is:
50mm
40mm
30mm
115kg/m2
100kg/m2
85kg/m2
If you do not build a base layer, surface drainage is not assured. Not only that,
movement in the natural soil can cause unevenness. ECOGRID® considerably
increases the load capacity of the surface, but it goes without saying that even
ECOGRID® will be tested to its limits if the entire ground gives way extensively.
Example:
ECOGRID® WITH RESIN BOUND
DekorGrip Resin Bound stone 20mm layer ®
ECOGRID®
Base Layer
Floated over the top of the filled grid, edged with ECOGRID edging
Fill in the ECOGRID
Gravel/sand/chippings: Fill in the grids with appropriate material
Levelling course
Put on a layer of 2-10 mm chippings (height approx. 20mm) and level off

Draining layer
A 150-300mm depth of well-compacted
non-frost susceptible, Type 3 (open
graded) sub base to SHW clause 805
Drainage layer
Depth will depend on sub-base and traffic for which the surface is designed for
Foundation
Natural soil
Create an approx. 1 - 1,5 % gradient in the ground

INSTALLING THE RESIN BOUND
Prepare the EcoGrid surface as previous page (Do not infill)
Prepare curves and straight edges
Afix the edging strips giving a 20mm riser above grid level
Infill grids and compact to approx 2mm below surface with 5-10mm sharp angular stone
Prepare resin and stone quantities to advised amounts - 2.94 square metres per resin kit with 100kg of aggregate
Mix in batches of 2.94 square metres in a force action pan mixer
Pour the mixture on to the surface and level using a wooden lute
Float smooth with a resin trowel ensuring a firm, even surface
Allow to cure
Ensure expansion and contraction joints are ‘cut in’
AVAILABLE BLEND OPTIONS:
TIPS
Ensure aggregates are completely dry when mixing and free from fines
Curves and patterns are easy with a carborundum 8mm blade. Edges slot in to the cut
shape and provide a level guide (Can be removed if laid with cling film on the leading edge)
Ensure when ordering that you allow for 5% over just in case
Allow at least 4 hours for curing (weather and temperature dependent)

INSTALLING THE RESIN BOUND
5 cm
If there should be some kerbstones,
make sure to leave a gap of min. 5 cm.*
ECOGRID® is quick and easy to lay without machinery. The system is delivered in
preconnected units of 12 sections and can be taken straight off the pallet and laid
in one go.
90°
The ECOGRID System should be installed
level to surrounding edges.*
INSTALLING
To lay the grids, start in one corner of the area. The lugs of the first row must point in
the direction you are working in. The subsequent rows are then pressed into the lugs
of the laid surface.
We recomend to use a string line when installing ECOGRID.
DISCONNECTING
The preconnected sheets can be taken apart if necessary. Lay the sheet you wish to
take apart on another sheet and, using your foot, press the tiles you want to remove
down and out of the safety locking system.
FITTING – cutting to size
For quick and clean tile cutting, the following tools have proved most effective in
practice:
• Circular saw
• Flex (cutting disk)
• Reciprocating saw

To avoid surface distortion at the edges caused
by the shear forces of cars, the ECOGRID
System can be fixed with ground anchorsat
the rear end of the parking area.*
As an alternative to ‘J’ pins you may
also just press down the rear part of the
ECOGRID*

TIP
ACCESSORIES
For quick and clean cutting to size, a circular saw has proved
most effective in practice. For smaller corners which must be
cut exactly to size, we recommend that you use a reciprocating
saw or sharp hand saw. Do not cut the grids in advance.
If possible, lay them over the border and then cut them. Use a
small base (slat/ board /ECOGRID® tile) to make it easier to cut.
Slope angles
Universal Slope angle adjustable up to 90°
Curve pieces
Ground anchor
Geotextiles
Edge strips to form levels and retainers
Edge strips anchor connectors (10mm drill bit required)
SPECIAL INSTRUCTIONS
It is imperative that an appropriate expansion joint and
contraction joint is maintained throughout the
perimeter of the installation.
A complete range of recessed manhole covers from
300mm to 900mm square, round and rectangular
DISCLAIMER
ECOGRID offers this document as a guide only.
Fitting of resin bound surfaces should always be carried out by a suitably
qualified professional.
