Design grass emergency lanes and permeable parking areas with the industry’s toughest performing porous pavement system. GEOBLOCK®5150 rigid grass pavers provide unparalleled load distribution (up to H-20 loading), a high resistance to rutting and torsional loading stresses, and excellent turf protection. Topsoil infill and engineered base allow a high rate of stormwater infiltration and offers an excellent growing medium for quick grass growth and grass life. Less base = less excavation, less fill material, and less cost.
