Grasscrete

Grasscrete - A cast-in-place, monolithic, porous concrete pavement that is continuously reinforced to provide superior structural integrity. After the concrete is sufficiently hardened, the voids are filled with topsoil and grass, thus providing a free draining "pavement" with the structural capacity to handle most heavy vehicle loads.

Great for emergency access lanes, delivery access routes, overflow parking areas, and for intermittent drainage channels to help prevent erosion.
