Water entering your basement can have a negative effect on your health, as well as your wallet. When water enters your basement mold can grow behind finished walls and damage floors. Mold growth on organic materials is a hazardous contaminant and can further damage your home, but that won't be a problem with the help of Mr. Sponge Waterproofing, Inc.

Our basement waterproofing services have been assessed by Sanit-Air, Inc., an indoor air quality company. Santi-Air tests determined that mold levels in our serviced basements have decreased by 92% after two weeks.

Our process will inject proprietary SP3 polyurethane into the smallest of basement cracks and follow the path of water in reverse to its entry point on the opposite side of the poured concrete foundation wall, then activate and permanently seal the path.

We are so confident in our service that it is guaranteed with a transferrable warranty.
