Dampproofing
Dampproofing is a basic coating on foundation walls that resists moisture but is not full waterproofing.
Why it matters
In high water situations, dampproofing can be overwhelmed.
Where people get this wrong
Dampproofing is not the same as waterproofing. Drainage is still required even with good coatings.
Real-world example
A homeowner assumes the black coating on the foundation means waterproof. Then they finish the basement and get moisture behind drywall. The coating might have been dampproofing, not a true waterproof system.
Where this hits your build
This matters during site work and foundation. Mistakes here get buried and are expensive to fix later. Pay attention before concrete is poured.
Most people do not just struggle with terms. They struggle with the decisions tied to them.
