Great Lakes Waterproofing

Great Lakes Waterproofing is a foundation and basement waterproofing contractor that focuses mainly on exterior work, using bentonite products to stop water at its source outside the foundation. The company also installs drain tile, sump pumps and industrial wall coatings for some customers, and uses thermal imaging equipment to find wet areas.

The company works with homeowners, apartment buildings, hospitals, schools and realtors or general contractors. Because exterior bentonite work usually avoids digging up the foundation or removing wall coverings, it can often be done without tenants moving out or staff stopping work inside. Free estimates are offered, and the office is at 455 Minnesota Street in Saint Paul.
