ALVÉODRAIN P5 - Water barrier, protection and drainage of basement walls

Marquage CE


When building structures, there is a risk of run-off water stagnation when in contact with the walls, which may jeopardise the longevity of buildings. This is why the foundations should be protected with a drainage and water barrier system.

Consisting of a filtering geotextile, a draining geotextile and an impermeable film, ALVÉODRAIN® P5 simultaneously provides buried walls with protection, drainage and a water barrier (car park, residential basements, business premises, retaining walls, etc.).

Run-off water is discharged into a collector drain at the bottom of the wall.
