What is the difference between damp proofing and water proofing a basement foundation wall?
Damp proofing means coating the exterior foundation wall with a special tar-like sealant to protect the wall from moisture penetration. Waterproofing is when there is an actual membrane, usually rubber, that is applied to the surface of the foundation wall as a complete water barrier. We recommend weeping tile also be installed at exterior of the footing to take away excess water from the house. Please note rain water leader should not be intalled directly to the weepers as this can cause flooding problems.
