Rainwater flooding

Flooding due to heavy rainfall or high surface water levels.

A grass tile is a grid where grass is sown and which is passable for vehicles. Grass tiles can cope with greater loads than other types of semipermeable pavement such as gravel, debris, pebbles or woodchips. 

• The rainwater is purified by infiltration.
• Greener appearance.
• Can cope with larger loads than other semipermeable pavements
