“No Digging” Basement Waterproofing method

Stop water from hitting your basement wall! Blocking water before it hits the wall increases the longevity of the foundation. This method requires homeowners to maintain their grading, gutters, and downspouts.

The “No Digging” Method

Stop water from hitting your basement wall! Blocking water before it hits the wall increases the longevity of the foundation. This method requires homeowners to maintain their grading, gutters, and downspouts.

We use an exterior injection method

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

Bentonite is recommended internationally by engineers when it comes to preventing water intrusion, although the term is often unrecognized because people in the industry call it “MUD.” Bentonite was used to contain the BP Oil spill. Bentonite is also used when the Hoover Dam leaks, and it is the waterproof liner around every underwater tunnel system to-date, e.g., including the tunnel between Michigan and Canada. Engineers love Bentonite because it does not crystallize or disintegrate. So, as a foundation shifts and settles, the Bentonite shifts and settles with it. The government likes Bentonite because it is a completely natural material and it will not harm animals or plants.

How It Works


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 principles when blocking water from touching foundation walls by coating them using a “No Digging” injection process.

Basement Waterproofing

We displace loose soil around the foundation and replace it with Bentonite clay by using low-pressure grout pump injection. This process creates a high-performance watertight membrane, from below grade to the footer. Limiting moisture from penetrating the wall increases the longevity of the foundation. This engineer-recommended process is used in residential, commercial, and industrial applications.

Most homeowners make landscaping a top priority when they first move-in…

“Many home and building owners make landscaping a top priority when first purchasing a structure, and then they discover a leaky basement. Great Lakes Waterproofing uses a BEST-IN-CLASS Bentonite clay injection system that involves NO DIGGING, which means that your landscaping can remain in place and water is kept away from your foundation wall from below grade-level to the footer.”



We store precious memorabilia, install insulation and drywall, and place furniture along with our basement walls just like you. Unfortunately, water can find its way into our homes no matter what valuables we have in our basements. As rain falls and travels below grade, it continues along a path of least resistance often toward the biggest hole in the ground – your basement! Great Lakes Waterproofing uses our NO DIGGING Bentonite clay injection system to seal-off water pathways, to HELP KEEP YOUR BASEMENT DRY, and to increase the longevity of your foundation and home.

Great Lakes Waterproofing offers a TRANSFERABLE WARRANTY FOR THE LIFE OF THE STRUCTURE, which also requires a team approach with homeowners who need to keep their gutters, downspouts, and grading in proper working order for any installed materials to be completely effective.

“No Digging” Waterproofing Process


A hollow rod about 1 inch wide is connected by a hose to a low-pressure grout injection pump. The rod is inserted vertically into the ground, along the exterior foundation wall.

Bentonite clay in a semi-fluid state is pumped with low pressure through the hollow rod that is placed against the exterior foundation wall below grade to the structure’s footer. In about 45 minutes, the Bentonite clay sets up resulting in a fairly solid, putty-like material. The Bentonite continues to expand for about the next 30 days as it forms a high-performance watertight membrane against the structure.

The high-bonding Bentonite clay expands into the structure’s cracks and fissures, forming a watertight membrane from below grade to the structure’s footer. The Bentonite clay mixes with the soil and expands up to 1 foot away from the external foundation wall, which limits moisture from penetrating the wall in the first place.

Waterproofing on the outside of your structure can help stop water before it finds its way inside the building. Bentonite clay is an all natural product that can 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.”

Very good customer service and communication about the project at hand. I would highly recommend Great Lakes Waterproofing.

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!
