ALVÉODRAIN Ev - 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 must be protected with a drainage system.

ALVÉODRAIN® Ev is applied vertically in contact with basement : car park, residential basements, engineering structures, business premises, retaining walls. It simultaneously protects and drains run-off water discharged to a collector drain at the bottom of the wall to avoid any accumulation in contact with basement walls.

An alternative, more resilient solution is possible by installing ALVÉODRAIN® F and its thicker alveolar geocomposite.
