Common questions
Should waterproofing be done inside or outside?
It depends on the source, access, foundation construction, and site conditions. An on-site look helps determine the practical approach.
Can poor yard drainage cause basement water?
Yes. Roof runoff, low spots, and water held against the foundation can contribute to basement seepage.
