Infiltration slabs

Infiltration slabs are very sturdy and also flat. You can use them if you want to infiltrate water under a paving, such as under a driveway or patio.

Infiltration slabs are lightweight and can be laid horizontally under a patio or in the garden. The special feature of this solution is that plants and shrubs can soak up groundwater through the infiltration element during dry periods.

You place infiltration plates at:

• a high water table;
• when excavators cannot be used;
• You want to infiltrate under the patio or a driveway.

Points of interest

• In a topsoil with a lot of clay or loam, this measure is not useful because water does not sink quickly into the soil.
• For infiltration under a terrace, minimum distance from a facade with crawl space: 2 meters; minimum distance from a facade with basement: 3 meters.
