Drivable Grass® is a permeable, flexible, and plantable concrete pavement system. This product is made of wet cast, low moisture absorption concrete. Drivable Grass® is cast with holes to allow for infiltration and root penetration. A cast-inside engineered polymer grid allows Drivable Grass® to flex and conform to irregular ground surface contours along pre-defined linear grooves while providing the intended structural support needed for daily use. Drivable Grass® maintains its load-supporting characteristics even when saturated. The design also eliminates sharp edges common in other products, and won’t crack and break like rigid concrete or pop up like plastic.
