Greatl Lakes Waterproofing Hydroclay Injection Process

It is likely that your basement will develop leakage of some kind during its lifetime!

The age of the structure does not matter. We see many leaks in homes under five years old.

There are many causes of basement leakage:
1. Cracks in walls and floors due to structural changes such as settling.
2. Insufficient runoff due to improper landscaping and high clay content.
3. High water table.

The solution for cracks and poor run-off is our patented Hydroclay-Injection system. Water can enter block walls due to decay, cracks and missing mortar. It often comes through the seam between the wall and floor along poured-concrete walls.

With our patented Pressure Pumping Process, we have eliminated the need for digging. There is no damage to sidewalks, driveways and landscaping.
During the process, Bentonite Clay is injected into the soil around the basement at 3-4ft intervals. The Bentonite coats the walls from footing to grade.

As the Bentonite absorbs groundwater, it swells up to 15 times it's volume and thickens, creating an impenetrable gelatin membrane, which protects against further water penetration.

This system is effective against water entering cracks and tie rods in poured walls, and mortar joints and pores in block walls.

Another effective means of waterproofing with Hydro-Clay is in the panel form is Volclay Panels.

Sheets of corrugated cardboard are filled with Bentonite. These sheets are applied to the walls before backfilling. After repeated wetting, the cardboard decays, leaving a layer of Bentonite against the wall. Wall cracks which can be excavated can also be sealed in this manner.

The Hydro-Clay Bentonite is unchanged with age. Once it is in the ground, it is a permanent repair. Should structural changes occur after application, the Hydro-Clay Bentonite will move with the soil to fill any gaps that may develop within the walls.

There are certain instances where the Hydro-Clay Bentonite alone would not be sufficient enough to solve your water problems.

These instances include water which enters the basement above the concrete foundation (due to improper landscaping), water which enters block walls above grade (due to improper landscaping), water which enters block walls above grade (due to decayed and missing mortar), and construction debris dumped against outside walls before backfilling, by contractors who do not want to carry it away.
In the latter case, the Hydro-Clay Bentonite cannot completely coat and seal the walls.

If one of these or other unforeseen conditions exist, a Drain Tile or Flume System would be installed.
