The membrane is made from tough, long lasting plastic that keeps exterior moisture out. It prevents backfill material from touching the foundation wall and bridges typical wall cracks with ease.
The dimples in the membrane create a drainage space that allows the wall to breathe. It keeps 100% of the headwater pressure off the face of the wall. This space allows moisture to condensate outward on to the membrane. By gravity, the moisture then falls to the footing drain for removal.
