Product code: ESC-CHECKERBLOCK
Perforated concrete slabs for reinforcing grass – a permeable surface for pedestrians and vehicles.
Checkerblock is a system of perforated concrete slabs that reinforces grass in urban settings, protecting it from erosion caused by pedestrians and occasional light vehicles and preventing puddles. Each square slab is a grid of 9 pavers, each 7.5 cm wide, joined by concrete ribs hidden beneath the vegetation, with grass filling the gaps.

Green car parks, driveways, emergency access routes, slopes and pedestrian areas where grass and the natural rainwater cycle should be preserved.
For good grass growth, fill the openings with topsoil and seed them; where no grass is needed, sand can be used instead.
