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 buried foundations : 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 buried walls. An alternative, more resilient solution is possible by installing ALVÉODRAIN® F and its thicker alveolar geocomposite. • 30% installation time saved • 3 basic functions in just one operation : drainage, filtration and mechanical protection • Very flexible, light product, making installation easier in corners • Quickly implemented • Cost-effective and environmentally friendly solution which avoids the use of drainage materials at the bottom • Installed on any substrate, horizontally and vertically • No uprooting when backfilled • Mechanical protection of the waterproofing layer, when there is one •
