Exterior Waterproofing

Great Lakes Waterproofing has provided foundation waterproofing solutions for over 30 years including exterior waterproofing for new and existing homes and business.

For existing homes we use our exclusive hydroclay pumping and injection equipment to waterproof your basement. With little or no digging we waterproof the foundation from the outside. Due to the specialized nature of the process our installers are required to complete a rigourous training course covering the basics of exterior waterproofing and ground hydrogeology.  

Do you have a brand new home or building? Before the ground is backfilled Great Lakes Waterproofing will attach Volclay, Voltex or Miraclay Sheets to the exterior, giving you the confidence of all green Bentonite Waterproofing

In this photo Mike is injecting benonite hydroclay under the garage floor, this wet basement had water coming in from the garage side of the home underneath the concrete garage floor.
Mike is waterproofing an exterior wall with our bentonite waterproofing injection process. Using a waterproofing blend of bentonite, Mike positions the bentonite injection equipment within one foot of the exterior wall that needs to be waterproofed
The injection wand is pushed down to the footing, the strip of concrete the wall is built on, and bentonite pumping begins. See the snow in the photo? Our installers work year-round. and only need to waterproof the area where water is entering the wet basement

After injection of the hydroclay is complete, Mike moves down three feet and starts the process over again until he has waterproofed the entire area with all green bentonite waterproofing
Exterior waterproofing stops water before it gets in your basement. Bentonite Hydroclay is an all natural green product that should last the lifetime of your structure.

Over time the soil around your foundation settles forming voids and water channels

Water builds up in these areas under pressure pushing against the walls and footing

Unprotected foundation concrete develops cracks and holes allowing the water to enter the basement

Using our exclusive bentonite injection system Great Lakes Waterproofing injects Hydroclay down to the footing and up to grade level

Acting like a sponge, the Hydroclay absorbs water 15+ times it's original size filling voids and cracks forming a permanent membrane barrier

Unlike other materials which dry and become brittle, Bentonite Clay permanently stays flexible providing a self-healing waterproof barrier

Bentonite is an all green material mined in Benton Wyoming. Sometimes called hydroclay due to it's unique ability to absorb large amounts of water, this material is used for several applictions including lubrication for oil well drills, kitty litter, clarifiying white wine and of course waterproofing.
