Basement Waterproofing — quick answer

Basement waterproofing stops water entering below grade by combining exterior membrane or damp-proofing on the foundation wall, working perimeter drainage, and interior repairs where needed. In BC's rainfall, exterior waterproofing done while the foundation is already excavated is the durable fix.
