Basement Waterproofing in Overland Park, KS | Heartland Foundation Repair
Last updated April 2026
Wet basements in Overland Park are almost always a soil and drainage problem. The clay around Johnson County doesn't drain — it holds water and pushes it against your foundation walls for months after every storm. We stop it at the source.
OP's biggest building boom was the '60s through '80s. Those homes are 40-60 years old now, right when clay movement overwhelms the original construction. We've been here through all of it.
Foundation piers, wall stabilization, waterproofing, crawl space work, spray foam, concrete leveling. Every structural service under one company.
We're in OP every week without fail. (913) 270-0250 — free inspection, written estimate on the spot.

Frequently Asked Questions — Basement Waterproofing in Overland Park
Why do finished basements in Overland Park flood?
Most OP basements were finished without waterproofing the walls first. The clay outside saturates during spring storms and pushes water through microscopic pores and cracks. You might not see a gusher — just damp carpet, a musty smell, or mold behind the drywall.
Can you waterproof a finished basement without tearing everything out?
In many cases, yes. We can install a drain system along the exposed perimeter and minimize how much of the finished space we need to open up. Sometimes we do need to remove a strip of drywall along the base of the wall, but we work to keep disruption to a minimum.
How much does waterproofing cost in Overland Park?
Interior drain systems with a sump pump run $4,000-$10,000 for most OP basements. Crack injection is $500-$1,500 per crack. We come out for free and give you a detailed written estimate.
