“No Digging” Waterproofing Process

The Bentonite Injection is Ideal for:

  • Wall cracks
  • Mortar joint cracks
  • Cove joint issues
  • Porous walls
  • Moist Walls

Drain Tile Installation/ French Drain System

Drain Tile systems are necessary when a home is located on a high water table or there is excess water pressure building up under the concrete floor. This is the only solution for hydrostatic pressure (under floor water).

Crawl Space Encapsulation

When exposed to harsh weather conditions, regular plastics become brittle and easily crack. Researchers discovered that using Polyethylene as the base material prevented this rapid molecular break-down, and provides a long-lasting material that can survive wet crawl spaces in harsh Midwest temperatures.Using two layers of Polyethylene based material wound with nylon, we are able to extend the product’s life by almost 7 times!

This material has a similar appearance and texture as a pool liner.

Carbon Fiber Strips & Kevlar Neckties

Rather than allowing external pressure to focus in one area (typically the center of the wall), Carbon Fiber Strips distribute the pressure and prevent wall collapses. At Great Lakes Waterproofing, we install Kevlar Neck Ties with each installation. This relieves additional wall pressure and applies it where it should be – the supporting joists. Additional Perks:

  • As thick as a dime
  • 10 times stronger than steel
  • Non-corrosive and non-flammable
  • Lifetime warranty from the manufacturer

Elevator Pit Waterproofing

We specialize in waterproofing hydraulic and electric elevator pits by using 6 main processes to ensure the pit is completely water-tight and follows all ASME codes and regulations.

  • Bentonite injection to prevent wall water
  • Above footing tile system to stop cove joint water
  • Sump Pump installations for hydrostatic pressure (includes Regular, Oil Sensor, and Oil Separator pumps)
  • Floor raising and re-leveling
  • Stabilization for cracks, crevices, and weak spots in the wall
  • Epoxy Coating to prevent moisture/humidity build up

I-Beam Installation

When a wall is crumbling or cinder blocks have shifted out of place, Carbon Fiber Strips are unable to stabilize as designed, and it becomes necessary to install steel I-beams. The process used by Great Lakes Waterproofing is the most highly recommended by engineering firms internationally. We attach the I-beams to the most structurally secure places in the home: The footing and the Sill plate.For additional stability, we brace the supporting floor joists three to four joists away from the wall. This spreads the extreme external pressure between several different joists, rather than centrally locating the pressure.

Satisfied customers since 1978

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!

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.
Mark K.
“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.”
