Exterior Waterproofing is designed to protect and stop the transfer of moisture from soils to the concrete wall.
A foundation sealant coating is applied to the wall first. An air gap drainage membrane (dimple board) is placed over this and a mastic sealant used to seal the top edge and vertical seams.
The drainage board is fastened near the top of the wall with special fasteners. A four-inch perforated weeping tile fitted with a filter sock and encased in clear stone, is installed along the top of the footing.
