Waterproofing basement

✅ The dimples 〰️in the membrane create a drainage space or airgap between the wall and the back of the membrane that allows the wall to breathe. . ✅ This space also allows moisture to condensate outward on to the membrane. . ✅ The backfill rests on the outside of the membrane and water can not penetrate through the plastic. . ✅ Surface water migrates down through the backfill to the drain stone and into the drain pipe at the bottom, near the footing. . #construction #waterproofingbasement
