A grass paver block is a concrete paving element with open cells — often in a honeycomb shape — that are filled with soil and grass after laying. This creates a surface that carries the weight of vehicles yet still looks green and lets rainwater through. Grass paver blocks are also called grass concrete blocks.
How it works
The concrete ribs of the block take the load and distribute it to the subsoil, while the open cells provide space for grass or gravel. Rainwater soaks away between the cells into the ground instead of running off to the sewer. Grass paver blocks are therefore a form of semi-paving.
Application
- Car parks and driveways — a load-bearing, green surface
- Verges and emergency lanes — drivable yet vegetated
- Fire-brigade standing areas and access roads — paving that looks green
- Banks and slopes — as a cover against erosion
Advantages
- Water-permeable — helps counter flooding and drought (climate-adaptive)
- Green appearance — less hard surfacing than closed paving
- Load-bearing — suitable for light to medium-heavy traffic
Point of attention
A good, water-permeable foundation layer is essential. The grass growth in the cells requires maintenance and enough light and water.
