Great Lakes Waterproofing

Serving the Midwest for over 30 years, Great Lakes Waterproofing waterproofs below-grade from outside your basement, garage, condo, elevator pit. Using our exclusive Hydroclay Injection System we seal leaks and cracks and prevent moisture from entering.

Great Lakes Waterproofing's Technology works from outside of your house....where experts agree is the best place to stop grade level water from getting into your basement.

Unlike other methods requiring excavation either inside or outside the structure, our factory-trained waterproofers use injection equipment outside with little or no damage to your landscape or structure.
