House foundation repair in Washington DC helps a building maintain structural integrity. When a contractor says a home needs foundation repair, the homeowner should not ignore this. Foundation problems can only get worse and may eventually create hazards in the home.
Helical Piers
A settling or sinking foundation can be repaired with helical piers. The structure of a home is reliant on support by the footing. Piers are necessary when the footing becomes vulnerable.
Piers are installed deep into soil that is more stable. The piers are installed in a load bearing stratum. Then the foundation is lifted, returned to a normal support system, and locked in place.
Wall Tiebacks
A wall that has cracking and movement that may cause bowing of the walls can be repaired with wall tiebacks. They are mainly for walls where lateral movement needs to be prevented. Tiebacks work well at preventing further movement of the walls, and they cost less than having a foundation rebuilding repair.
Here is how walls are stabilized with tiebacks. Cement block is opened to about eight inches. The helix is put in with the lead section. The crew spins the helix deep in the soil all the way to the exterior of the structure. The twisting force is done until a locking load is achieved. The helix is locked in and a threaded rod is connected. New brick and mortar is replaced where the hole in the cement was.
Carbon Fibers for Bowed Basement Walls
A bowed basement can happen when soil pushes against the foundation. That and other lateral forces can make the foundation weak. This can create a compromised foundation and cracked walls if it isn’t fixed in due time.
Carbon fibers tie to the base of the foundation and the frame of the house for dual support. A sill plate is fastened to the carbon fiber with a bracket. It is then secured to the floor by a carbon fiber pin. This type of repair fixes bowed walls and foundation cracks. Labor cost is reduced because the whole project is done in the basement.
