Floor Crack & Cove Joint Seepage
Foundation floor cracks are caused by settling, shrinkage and stresses as concrete cures. Often, but not always, hydrostatic pressure will force water up from under the floor or through other types of leakage areas in the walls. In cases where hydrostatic pressure is present, sealing the floor is not an option, as water will typically build up elsewhere.
An inherently weak spot on any type of foundation, a cove joint is where the footing, floor slab and wall meet. Under certain conditions such as prolonged rain, ground water and resulting hydrostatic pressure along the foundation walls and underneath the basement floor can cause water to seep upward through this joint. Sealing a cove joint is not an option, as the water is likely to build up somewhere else within the foundation.
The Water Trek System® is perfect for this situation. It is an adaptable system that can be installed on, or in front of the footing.
- Before installation, all footing configurations are identified and solution configurations are investigated for each particular construction aspect in relation to floor and the existing foundation.
- A narrow trench to accommodate the configuration is then excavated at the interior base of the wall.
- The Water Trek System is placed into position and tested before being cemented back under the floor.
- The Bulldog Water Grabber, a patented sump liner, is installed to discharge the water as it collects.
The Water Trek System effectively relieves the upward hydrostatic pressure and water now entering the basement is channeled into the evacuation tubes to the Bulldog evacuation pump and out of the basement.
Foundation wall cracks are caused by settling, or water pressure due to the seasonal cycle of freezing and thawing. Typically these cracks run vertical or diagonally from the top of the foundation down and extend to the exterior. Unfinished basements can be repaired from the inside and finished basement cracks can be repaired from the outside. These types of cracks rarely pose structural issues, but it is typical for them to leak.
Depending on the foundation wall material, various solutions are available to seal these cracks., but typically we use a polyurethane injection to fill the crack which is further sealed by a Techni-Crack™ Hydrophobic Membrane. The polyurethane expands to fill the complete crack before it solidifies and plugs the gap. The final state of the polyurethane is a firm gel like substance that has the ability to expand and contract with the seasonal changes in temperature. Our final step is to cover the entire crack on the interior with a water proof membrane. This ensures that if any additional spider cracks develop off the side of the main crack, that they will be covered and the home will remain protected. Homeowners can be assured they have a worry free solution in place. Warranted for life.
