Real solutions involve:
? Waterproof membranes
? Interior drainage
? Pump systems with backup support
This Old House explains why true waterproofing goes beyond surface treatments in this article.
Mistake #3: Overlooking Cracks in the Foundation
Some foundation cracks look harmless, but others signal structural trouble. DIY kits can cover visible gaps—but not solve the cause.
Fix them by:
? Getting a professional assessment
? Using high-quality injections
? Adding relief systems to prevent pressure buildup
Mistake #4: Attempting Waterproofing Without Experience
DIY methods without knowing the risks. Common missteps include:
? Not cleaning the surface first
? Installing systems without inspection
? Not finding the source
When in doubt, schedule a consultation.

Mistake #6: Ignoring Humidity and Mold Risk
Waterproofing is only part of the solution. Basement moisture levels helps prevent:

? Push water away from the structure
? Prevent pooling near the edge

? Vague contracts
Instead:
? Recognized waterproofing training
? Guarantees on work
? Verified track records
Sites like HomeAdvisor and Angi offer mold prevention verified contractor listings and customer reviews.
Mistake #9: Confusing Damp-Proofing with Waterproofing
Damp-proofing blocks moisture, not active water. True waterproofing involves:
? Rubberized barriers
? Drain tiles
? Pumps
Mistake #10: Addressing Only Interior or Exterior
