Homeowners can identify concrete foundation issues from cracks in the basement, either on the foundation wall or on the floor. These cracks are typically due to drying shrinkage, thermal movement or other causes. Foundation cracks can widen over time and result in wet basements or more serious structural problems. Foundation and slab cracks are not only an eyesore, but they may lead to more serious maintenance issues, while lowering the value of the home.
There are numerous methods for the repair of settled and unstable foundations. These repair methods are most commonly referred to as Piering, Underpinning, Foundation Stabilization and Foundation Lifting. Due to the complex nature of these types of foundation problems, the correct repair is critical. A-1 Concrete Leveling Johnson City Tennessee will assess your foundation and provide the best and most economical solution for your particular situation.
Foundation Crack Repair
There is an easy way to permanently repair foundation cracks without the need for costly and disruptive excavation or drain tile. Poured foundation cracks can be repaired by the A-1 Concrete Leveling patented process, which uses a two-step Epoxy/Urethane injection.
The Epoxy paste is used to set injection ports every 6" from top to bottom of a foundation crack, and to bridge the surface of the crack. The Urethane is then injected into each individual port, which than expands to fill the entire crack from the top to bottom, filling the void and providing a strong, solid repair.
Bowed Foundation Walls/Basement Repair
Pressure from the exterior ground soil can cause block foundation walls to bow and deflect inward. If left unchecked, this condition can result in catastrophic failure.
Our method of repair involves installing temporary braces on the interior foundation walls, then excavating the exterior ground around the bowed section of the foundation. The bowed walls are then mechanically pushed back into place, and steel rebar is inserted vertically into each block before pumping the wall full with high quality concrete, which is allowed to cure fully. We then backfill the ground soil, and the braces are removed from the foundation walls after 3-5 days. This method not only pushes the wall back into place. it also stabilizes the structure to prevent future bowing. Best of all, there are no unsightly plates and screws permanently installed on the interior basement walls.
