A grass grid tile is a tile or grid made of concrete or plastic with openings in which grass or gravel can grow. Like the grass paver block, a grass grid tile provides a surface that is both load-bearing and water-permeable, with a green appearance. Grass grid tiles and grass paver blocks are very similar; grid tiles are often thinner or made of plastic.
How it works
The tile takes the load through its ribs or grid and passes it on to the subsoil. Grass grows in the open cells, while rainwater soaks away between the openings into the ground. In this way the surface stays walkable and drivable without being fully paved over.
Plastic grass grid tiles
Besides concrete versions there are lightweight plastic grass grids. These are laid on a firm sand or gravel layer and seeded with soil. They are light, quick to lay and mainly suited to lightly loaded areas.
Application
- Parking bays and driveways — load-bearing and green
- Garden paths and terraces — water-permeable, natural surfacing
- Verges and slopes — protection against wash-out
- Event grounds — temporary, walkable grass areas
Advantages and point of attention
- Advantage — water-permeable, climate-adaptive and green
- Advantage — reduces flooding and heat stress
- Point of attention — a good foundation and enough light and water are needed for healthy grass
