Basement Leaks After Heavy Rains? Causes and Permanent Fixes

Basement leaks after heavy rains typically happen when water builds up around your foundation and slips through cracks, weak spots, or poor drainage pathways.

What's Really Happening When Your Basement Gets Wet

When heavy rain hits, several forces work together to push water into your basement. Understanding these causes helps you choose the right fix—not just a temporary patch. Typical problems include:

Water pressure builds up around your foundation
Foundation cracks let water find its way inside
Your drainage system gets overwhelmed
Groundwater pushes up from below- After several days of rain, the water table in your area rises. When it gets high enough, water can actually push up through cracks in your basement floor. This looks different from wall leaks—you'll see water bubbling up from floor cracks while your walls stay dry.

Real Solutions That Keep Your Basement Dry

Once you know where the water is coming from, we can fix it for good. With over 70 years of combined experience in basement waterproofing, we’ve seen every type of leak—and we know exactly which solutions work.

Interior Drainage Systems

Interior drainage systems control serious water issues by channeling natural groundwater movement safely away from your basement.

For homes that experience flooding during heavy rain, sump pump systems offer crucial defense by pumping water away from the foundation.

Foundation Crack Repair

Water is halted at its entry point using engineered materials designed to move with your foundation over time.

Rob from Best Buy Waterproofing came highly recommended by our friend Ashley, who recently had her French Drain installed, and I’m glad I took her advice. Our job was a redo of a lackluster non-code complaint system installed by a 'pickup truck guy' who didn’t do a great job and left us with ongoing issues. Don’t make the same mistake I... Read More »
