Permeable block paving

Areas of Expertise (2)


Permeable block pavings play an important part in an integrated water management policy, which aims at minimizing flooding risks by keeping water in place for as long a time as possible. Using a concept of full-depth permeability from the surface to the subgrade, rainwater is buffered (preferably) in the subbase layer, and allowed to infiltrate into the subgrade soil if possible. Permeable block pavings are used as buffering and infiltration systems for parking areas, squares, low-volume roads, cycling tracks, etc.

Measurement of surface permeability in situ: double ring test

This test is used to determine the permeability of a water-permeable structure in situ. The apparatus consists mainly of two rings (Ø. 50 and 70 cm), a continuous water supply unit and an automatic system to maintain a constant water level.
