East Lenexa went up in the 70s and 80s and those foundations have taken 40-plus years of clay. The newer builds out by City Center have a different issue: graded fill that settles under the house. Both end up calling us.
Basement Waterproofing in Lenexa, KS | Heartland Foundation Repair
Last updated April 2026
Wet basements in Lenexa 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.
The clay around I-435 and K-10 keeps our Lenexa crews busy year-round. Wet basements, bowing walls — same Johnson County soil story, and we know how to handle it.
Settling slabs, cracked walls, wet basements, crawl spaces, insulation upgrades. Full structural and moisture service for Lenexa homes.
Call (913) 270-0250. We're nearby and usually there the same day.

Frequently Asked Questions — Basement Waterproofing in Lenexa
Why do Lenexa basements leak?
The Johnson County clay around your foundation holds water and pushes it against the walls under pressure after every storm. In the older east Lenexa homes that pressure has been working on aging block walls for decades, finding cracks and the floor joint. Newer west-side homes leak where settling has opened gaps.
What's the best waterproofing fix for a Lenexa basement?
For most homes here it's an interior perimeter drain tied to a sump pump, which collects the water at the floor-wall joint and pumps it out before it pools. Individual leaking cracks get epoxy or polyurethane injection. We figure out the right combination during the free inspection.
Should I add a battery backup to my sump pump?
In Lenexa, we strongly recommend it. The same spring thunderstorms that flood basements are the ones that knock out power, and a pump without electricity is just a hole in the floor. A battery backup keeps it running exactly when you need it most.
How much does basement waterproofing cost in Lenexa?
A single crack injection is relatively inexpensive, while a full interior drain system with a sump pump runs higher depending on basement size and how many walls we address. The inspection is free and the written estimate is exact, no guessing off a website.
