Pavement Reinforcement Mesh
Installation Procedures for CompoGrid Systems
The following are general guidelines to ensure a successful
installation of CG50 and CG100. For each specific project,
a construction engineer will provide exact specifications
for installation.

Surface Preparations
• As directed by an engineer, repair potholes, cracks
greater than 6mm* ( 1/4 in.**), badly damaged or rough
pavement that may require milling and the placement
of a leveling course.
• Pavement must be free of dirt, water, oil and other
foreign materials. Broom or air clean the surface so
it is clean and dust-free.
• Apply tack coat uniformly over the prepared asphaltic
concrete surface at a residual rate of 0.9–1.36 litres/m2
(0.2–0.3 gal/yd2 ) using a calibrated distributor truck,
ensuring that the application rate remains constant.
The tack shall contain a minimum of 70% solids.

Road Surface Condition
• The road must be dry. Do not install CG50 or CG100
during any precipitation.
• The road surface temperature must be between 5°C
(40°F ) and 60°C (140°F ). On asphalt surfaces less than
24 hours old, the surface temperature shall be between
5°C and 46°C (40°F and 110°F ).

CG Placement Method
• Place the CG system while the tack coat is still tacky/
broken. Use a mechanical placement tractor or
place manually.
• Keep the material flat and wrinkle free. Installation
may require hand brooming. For sharp curves, cut
edges and fold over in the direction of the placement
of asphalt overlay.
• Overlaps must be a minimum 25mm (1 in.) to ensure
a continuous moisture barrier.

Manual Placement Procedure

Paving Method
1. Pave with hot mix overlay.
2. Asphalt overlay must be a minimum of 50mm (2 in.)
compacted thickness.
3. All of the CG system must be paved over on the day
of placement.

Important Issues
1. Because glass is a skin irritant, workers shall wear gloves
while handling CG.
2. To cut CG to the desired length, lay it over ironworks,
roll and then cut using a sharp utility knife.
3. CG must be applied so that the material lies flat on the
road surface with no ripples. Providing sufficient tension
during application will eliminate ripples.
4. Overlap all end roll joints 75–150mm (3 in.– 6 in.). Ensure
that the overlaps are shingled in the direction of paving
and that these overlaps also receive an application of tack.
5. Overlap longitudinal joints 25–50mm (1 in.–2 in.).
6.To maximize product performance, only construction and
emergency vehicles shall be allowed to drive on the CG.
These directions are a brief guide to installation. For complete
directions, consult with your CG distributor.
