What is the building code/requirements for a basement of a newly built home i.e. protection against water leakage - dimple sheets, weeping tiles, etc? Also what is the black coating that's put on the exterior walls of the basement?
I'm not sure what the min. requirements are in Alberta. But the basics are the weeping tile is a perferated pipe that has a sock on it to keep dirt out, this gets installed below or beside your foundation footings and is surounded by clear rocks to allow the water to flow freely. It ties into the city drain, a sump pump or a dry well.
The black coating is usually a flexable rubberized type that actually does the water proofing and will still seal even if the foundation walls crack a little.
The black dimple product allows a straight path for any water that does get in, down to the weeping tiles. It also protects against hydrostatic pressure forcing water through cracks in the wall, for places that have high water tables.
