The walls against the ground become damp from contact. Moisture and salts slowly degrade them. One solution is to create an internal casing (with or without a draining trench) and a draining membrane on the ground.

Our exclusive Hydro+ casing solution is guaranteed and has been proven since 1988.
For reinforced concrete structures (basements, car parks), resin injections are done in addition to the casing.
Depending on your situation, it will be possible to position, after making an external trench, a waterproof membrane between the wall and the ground. 10 years warranty
