Why You Need Foundation Leak Repair Services for Your Kansas City Home

Surprisingly, it’s very common to find water leaking from cracks in your basement walls and floors. If it’s not dealt with, it could lead to significant water damage and flooding in your property.

Foundation Leak Repair in Action

At KC Waterproofing and Foundation Repair, we use FlexiShield to fix your Basement or crawl space. Our crack repair system is designed to flex with the foundation and channel water from a leaking wall crack below the slab.

Foundation Wall Crack and Leak Repair in Kansas City Before and After

Top of the Line Basement and Crawl Space Crack Repair

As part of our foundation leak repair services throughout Kansas City, KS, and MO, we use a polyurethane injection system. We have been using this method since 1985. The polyurethane goes in as a liquid and expands, filling the void and causing a flexible seal between the two pieces of concrete. It consists of a strip of FlexiShield drainage matting and textured urethane sealant. It flexes with the foundation as it shifts during seasonal changes. It comes with a 5-year warranty and can be painted, giving you a dry and attractive finish.

Additional Options for Repairing Wall Cracks and Leaks

At KC Waterproofing and Foundation Repair, we always conduct a foundation inspection to discover the root cause of the crack before prescribing a foundation leak repair solution for your Kansas City home. Our basement wall leak repair team will work with you to determine the use of the space and ensure we meet your needs.

  • HD FinishShield is a 16mil, Class A (Fire-Rated) wall vapor barrier recommended as a durable wall covering. It’s perfect for basement walls where a customer may not finish right away, but would like the protection against moisture, mold, mildew, humidity, and potential wall leaks. The measured average permeance of FinishShield is 0.015 perm.
  • ThermalShield A 90mil, Class A (Fire Rated) foil-faced and true white poly wall vapor barrier. It’s the wall vapor barrier of choice for adding an additional installation reflecting indoor heat back into the basement space. Save energy and protect against moisture, mold, mildew, humidity, and potential wall leaks. The measured average permeance of ThermalShield is 0.014 perm.

Mario came out to redo an old crack from 25 yrs ago under the warranty. He was awesome. Super friendly. Noticed my son was military and spoke highly of that. Redid the fill and made it look better than before and cleaned up nicely. Thank you Mario!
