POROUS PAVEMENT

SYSTEM

WHAT ‘S GEOPAVE

?Geo-pave is a structural

framework designed for

confining and stabilizing porous

infill materials which infiltrates

the storm water.

Geo-pave is a range of

flexible two-component

polyurethane resin systems

which are formulated for

0.5m/20 inch

1m/40 inch

ENVIRONMENTAL BENEFITS & FEATURES

CONCLUSION:

The GEOPAVE systems are well-

suited for developing economical porous

pavements with either an aggregate or a

vegetated surface.

The economical pavement system is

made from recycled materials, effectively

addressing today’s stringent stormwater

regulations in an eco-friendly way.
