They are used when there is over-saturated areas depending on the terrain a 12×12 inch trench is dug then a 4 inch filtered, socked, the perforated pipe is placed in the trench and covered with gravel. Next, the wall is pushed back, the house is then lowered back on the foundation, and the walls are braced up. The exterior dirt in a wall is dug out to relieve pressure then the house is lifted momentarily to take the load off the foundation walls. Pushing back walls that are extremely bowed in when bracing is not an option. The placement of a subterranean pump that collects water through a catch basin and redirects it away from the property.Ī drain that is placed along the foundation footing to direct water to the sump pump and the pump redirects the water away from the house. Then, a two part material (polyurethane liquid) is injected into the ports, which then causes a chemical reaction that is activated by water causing a foam like seal within the crack.Īny sealing or repairing to prevent water intrusion into foundation/crawl space. When doing a crack injection, ports are placed 6-8 inches away from each other. Same as wall restraints, the only difference is the material is known to have 10 times the stencil strength of steel.Ĭarbon fiber staples embedded along the crack for resistance against reopening of cracks. They are used to stop and stabilize walls from inward shifting. They provide structural stabilization due to bowing from hydrostatic pressure.
