Recycled-polyethylene pervious-pavement grid system

Stabiligrid is an economical, easy-to-install, load-bearing pervious-pavement lattice grid. It is an environmentally sound alternative to pavement, effectively reducing storm-water runoff and allowing the underlying soil to absorb and process environmental toxins, such as cadmium, copper, lead, and zinc, and preventing the contamination of groundwater. Stabiligrid also reduces soil erosion, preserving vegetation and natural habitats.

Stabiligrid is lightweight but highly durable, and may be adjusted to fit existing contours using standard tools, such as an angle grinder or circular saw. The grids are typically laid on a 1 to 4 inch (2.5 to 10.2 centimeter) gravel base, depending on the porosity of the substrate below. The grid can be backfilled with gravel, sand, or top soil for vegetated surfaces. The grid facilitates a structural base for green roof systems and reduces both storm-water runoff and the urban heat-island effect.
