Checker Block is a steel reinforced, heavy-duty slab with thick webs ideal for commercial application. The unique waffle-like configuration of this pervious castellated product provides significant grass coverage when properly filled with topsoil. Each 4 square foot unit is 4" thick and provides a 75% grass to concrete ratio, ensuring a green turf that can support significant vehicular roads.
