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
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.
A job well-done is priority #1.
