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.
The consecutive retaining walls construction technique is increasingly used in major urban areas where space is becoming scarce.
ALVÉODRAIN® F, in permanent formwork or consecutive retaining walls, is intended to be installed vertically, on the filter side, against existing soil. It is temporarily fastened with nails before steel reinforcements are installed. It simultaneously protects and drains run-off water discharged via a weep hole.
ALVÉODRAIN® F can also be installed against retaining walls, engineering structure abutments and along buried walls, in the same way as ALVÉODRAIN® Ev. In this case, it is subject to a technical certificate validated by CSTB.
