What's the difference between waterproofing and damp-proofing?

Waterproofing is designed to stop water under hydrostatic pressure — the kind of force that pushes groundwater through walls and floors. Damp-proofing resists moisture vapor but won't hold back standing water. If you have active seepage or a high water table, waterproofing is the appropriate approach.

Do I need exterior or interior waterproofing?

It depends on access and the source of the water. Exterior waterproofing stops water at the outside of the wall and is the most thorough fix when excavation is practical. Interior waterproofing manages water from inside when exterior excavation isn't feasible — under a finished space, a tight lot, or a deck. Many homes benefit from both.
