Great Lakes Waterproofing installs the three major below-grade waterproofing systems, Drain-Tile, Cove and Bentonite Hydroclay Injections. While Drain-Tile and Cove systems are universally known, Bentonite Hydroclay is limited to contractors that have taken time for instruction on it's properties and installation. Specialized pumping systems are required to pump Bentonite at the right consistancy insuring years of life.

What is Hydroclay? Hydroclay is a term often used for bentonite, the clay with an appetite for water. Initially mined in Benton Wyoming, bentonite is now found world-wide. Great Lakes Waterproofing uses bentonite that is specially blended for waterproofing applications. The fillers added to the clay help with the corking action needed to plug up holes and gaps in your foundation wall.

For remedial work, on existing buildings, we use raw hydroclay pellets mixed with water to the exact consistancy needed for pumping. If you have a new project with exposed walls we can use Volclay Sheets tacked on the wall before backfilling.
