The foundation is excavated and steel piers are strategically placed to provide the needed lift. As the structure is lifted, concrete grout is injected into the void created under the foundation. The purpose of this grout is to evenly distribute the load, add additional strength, and prevent erosion and pest infestation.
After the structure has been repositioned, the piers are permanently locked off, filled with concrete and the foundation is backfilled to a rough grade.
Foundation Piering installation comes in a variety of forms: interior, exterior, location augured, location excavated and fully excavated. While all methods of foundation piering can be used to stabilize, in order to obtain optimum recovery, the entire foundation should be excavated (to top of footer).
By fully excavating the foundation, A-1 Concrete Leveling and Foundation Repair is able to inspect the condition of the foundation, reduce side friction and vertical load. This method, although more invasive, insures proper placement of foundation piering and optimum recovery.
Bowed Foundation Wall Repair
Pressure from the exterior ground soil can cause block foundationwalls to bow and deflect inward, resulting in catastrophic failure. Our method of repair requires us to brace the interior foundation walls, excavate the exterior ground soil. We will than push the walls back into place; install steel bars vertically into each block and pump wall full with concrete, allowing concrete to cure for 24 hours. , and backfill the ground soil, the braces are removed from the foundation walls after 3-5 days. This method not only pushes the wall back into place it also prevents future bowing to occur.
Foundation Crack Repair
While concrete cracks appear to be typical, it is not recommended that they remain ignored. Most homeowners best identify concrete cracks in their basement, either on the foundation wall or on the floor. They may also recognize cracks on the garage floor, patio or in-ground pool.
These cracks, typically due to drying shrinkage, thermal movement or other causes usually are minor and result in few problems. More often than not, a foundation crack will widen over time and result in water seepage, pest infestation or possibly the loss of structural integrity. Foundation and slab cracks are not only an eyesore, but they may hinder the value of the home.
Our foundation crack repair method is a two step Epoxy/Urethane injection. The Epoxy paste is used to set injection ports every 6" from top to bottom of foundation crack repair and to bridge the surface of the crack. The Urethane is then injected into each individual port, which than expands filling the entire crack from the top to bottom and out to soil completing the foundation crack repair all the way through the wall.
