“No Digging” Basement Waterproofing method

No digging waterproofing prevents water penetration at the source – outside. By blocking water before it hits the wall, it will increase the longevity of the foundation, and keep water from flooding your footing- the base your entire home is built on.   This method requires homeowners to maintain their grading, gutters, and downspouts.

The “No Digging” Method

Great Lakes Waterproofing uses a NO DIGGING Bentonite Clay injection system to seal-off those water pathways and keep your basement walls DRY FOR GOOD!

Stop Water from Hitting Your Basement Wall!

We use an exterior injection method

Bentonite clay is used to stop wet foundation walls & leaky wall cracks.

Bentonite is recommended by engineers internationally when it comes to preventing water intrusion, but many don’t recognize the term because most people in the industry call it “MUD”.  Bentonite was used to contain the BP Oil spill,  it’s the material used when the Hoover Dam springs a leak, and it is the waterproof liner around every under-water tunnel system to date e.g. the tunnel from Michigan to Canada.  Engineers love it because it doesn’t disintegrate or crystalize – so as a foundation shifts and settles, the clay shifts and settles with it.   The government likes it because it’s completely natural so it won’t damage plants or animals.

How It Works

This engineer recommended residential, commercial, and industrial applications

When building a man-made lake, construction workers will spread a thin layer of Bentonite clay at the bottom.  The clay will absorb as much water as it can handle, then reject the rest – sealing the lake and preventing water from escaping into the ground.  We use these same principals, only rather than holding water in a lake, we block water from touching the foundation.  We do this by coating the exterior wall using a “No Digging” injection process.

Basement Waterproofing

By injecting material with low pressure grout pumps, we are able to displace loose soil around the foundation and replace it with Bentonite clay.  This creates a water tight membrane barrier that prevents water from hitting the wall on the OUTSIDE of the building, rather than allowing water to compromise the concrete walls through penetration, then divert into an interior drain tile system. Although this process happens out of site, is still compromises the home’s structure. By preventing moisture from getting to the concrete, it will increase the longevity of the wall. This engineer recommended application is used in residential, commercial, and industrial applications.

Hey, we’re homeowners just like you!


We store precious memorabilia, install insulation, drywall and place furniture along our basement walls just like anyone else. Unfortunately, the water outside doesn’t care what we want to do with our walls—once those rain drops travel below-grade, they just go for the biggest hole in the ground—your basement!

That is why at Great Lakes Waterproofing, we use our NO DIGGING Bentonite Clay injection system to seal-off those water pathways and keep your basement walls DRY FOR GOOD—so you can DO WHAT YOU WANT WITH YOUR BASEMENT!

Issues resolved from Bentonite injection include a LIFE TIME TRANSFERABLE WARRANTY (as long as your deed exists, so does our warranty! Just do us a favor and keep your gutters clean…:)

“No Digging” Waterproofing Process

The Process

A hollow rod about an inch wide is connected to a hose that runs out to a mixer-pump system inside the Great Lakes Waterproofing truck. The rod or tube is placed vertically up against a wall.

From the truck, Volclay Bentonite is pumped with low-grade pressure through the rod in a fluid state against the structure’s exterior all the way down to the footing, where it sets up to a fairly solid, putty-like material after 45 minutes, expanding slightly to form a high-performance water barrier around the structure.

The high-bonding Volclay Bentonite gets into the structure’s cracks and fissures, forming a water-tight seal from the ground level down to the structure’s footing. The bentonite intermixes with the soil and expands up to a foot away from the building, preventing water from getting up against the structure in the first place.

Waterproofing on the outside stops the water before it gets in. Bentonite is an all natural product that should last the lifetime of your structure.

Satisfied customers since 1978

We purchased our house from someone who had hired them initially. So we are a license transfer of warranty. We had them come out to our house twice to service some water issues and they very prompt, courteous and did an excellent job. It’s been around three years now and all is dry.

“It was very good. They were prompt, came exactly when they were supposed to, did what they were supposed to do, and the crew was pleasant. It was the type of experience that you’d want if someone was doing work in your home. The job took a couple of days and it has worked just fine.”
Dawn S.
Very good customer service and communication about the project at hand. I would highly recommend Great Lakes Waterproofing.

Very quick turn-around on work. Helpful people. Finally, I’m excited to be a home-owner!

I researched this company and discovered it invented the outside-injection process in the 1970s for sealing basements without having to dig up the ground/foundation. They understand the concept that, if the water is coming from the outside, you need to treat it from the outside to keep the water off the wall! Other companies only have the inside systems that don't address the source (external) of the water. Great Lakes has a variety of options, and the volclay-bentonite they provided for my house permanently stopped the water and mold!
