What is foundation waterproofing and when is it required?
Foundation Waterproofing is any of a number of code approved methods for treating the exterior of the foundation wall to prevent the passage of water through the foundation wall. This is different from the code approved dampproofing method of parging the block and applying a bituminous coating. A waterproofing system is required on all basement foundations with below grade habitable space, this means any room that is designated for anything other than storage. As a rule of thumb, if you will be installing drywall or any other interior wall coverings, then waterproofing is required. The Waterproofing system must be ICC approved.
