Regrettably, many homeowners make expensive mistakes during the process, thinking a simple patch or layer of sealant will solve the problem. Be it Columbia or any place with heavy rains and storms, steering clear of typical errors can save thousands.

Let’s explore the biggest waterproofing mistakes and how to dodge them step-by-step.

Key Takeaways

? Interior drainage
? Sump pump setups

Mistake #3: Not Addressing Foundation Cracks

Some foundation cracks look harmless, but others signal structural trouble. DIY kits can cover visible gaps—but won’t stop seepage long-term.

Proper repair means:

? Adding relief systems to prevent pressure buildup

Mistake #4: Attempting Waterproofing Without Experience

DIY methods can create bigger problems. Common missteps include:
