About Us

  • on Angie's List for 5 years
Serving the Midwest for over 37 years, the award-winning Great Lakes Waterproofing System works from outside your structure using all natural bentonite for waterproofing. For existing homes and businesses we use our Hydroclay Injection Process where bentonite is injected around the foundation sealing up the areas moisture has been entering. For new construction we use bentonite membranes, the number one waterproofing membrane world-wide. Used for construction of tunnels, skyrises, manholes, underground vaults and even homes, this all-green material is recognized for it's unmatched ability to stop moisture and even self-heal over smaller cracks.
