PUBLIC WORKS ALVEODRAIN EV

To dissipate hydrostatic pressures behind the concrete walls of underground structures (tunnels, covered trenches), a drainage and filtration system must be implemented between the rock or shotcrete wall and the cast-in-place concrete cover.

Installed in strips or over the entire surface, ALVEODRAIN^® EV quickly drains infiltrated water. Its integrated filter geotextile prevents the migration of particles into the product. The drainage core of ALVEODRAIN^® EV, composed of a dimpled polypropylene geotextile, increases contact between the shotcrete and the product. The structure of the geocomposite also allows it to adapt to irregular surfaces while keeping a high resistance to compression.

In addition to drainage, ALVEODRAIN^® EV offers mechanical protection of the wall and avoid any damage when backfilling. It combines the three functions: filtration, drainage and mechanical protection in a single product and a single installation.

• Effective drainage of infiltrated water
