Tunnel Waterproofing Minnesota
Designers for new tunnel construction should look into the benefits of Bentonite Waterproofing.
Bentonite Waterproofing can swell 15x it's granular size when in contact with water making a permanent barrier to water.
Uneven or rough surfaces do not hurt Bentonite's ability to stick to the surface and stop the water. Real Waterproofing from Great Lakes Waterproofing starts on the exterior, stopping moisture before it moves through the walls.
