Serving the Midwest for more than 45 years, Great Lakes Waterproofing works from outside your structure targeting the water and moisture problems. Using our Hydroclay Injection Process, where bentonite is injected around the basement foundation, we seal up the areas moisture moves through before it gets inside. Our no-digging approach leaves the area looking the same when we leave.
Our projects include homes, businesses, tunnels, parking garages, elevator pits, underground vaults and projects the other guys can't do. Bentonite is an all-green material (rated by HUD) is recognized for its unmatched ability to stop moisture and even self-heal over smaller cracks.
The Great Lakes Waterproofing sales crew identifies the problems with the help of moisture meters and inferred thermographs. Our estimates for home owners are always free and in most cases we can be out within a few days of your call. We don't believe in the hard sell, you make the decision on your own time.
