Basement Waterproofing

As specialists in foundation repair and waterproofing, Quackers Waterproofing & Basement Repair provides permanent and cost-effective basement waterproofing and repair solutions to one of the biggest problems facing homeowners, cracked and leaking concrete. We have done more than 10,000 cracks injections and performed countless basement stabilization and waterproofing projects.

Foundation & Basement Wall Stabilization

Our staff specializes in using carbon fiber technology, as well as Kevlar™ wall stabilization components for damaged foundations and walls. Our staff has been factory trained by Fortress Stabilization Systems, we have installed over 1,100 carbon fiber wall stabilization components.

Sump Pit & Pump Installations

Sump pits and pumps vary a great deal. A sump pit is no more than a large polyurethane bucket that collects water from the drain system, while a pump removes the water from the sump pit. We offer reasonably-priced sump pump and sump pit installations for your basement.
