Pier and Beam Foundation Stabilization
For homes with pier and beam, foundation repair may be needed more often. Repairs to a pier and beam foundation have two phases. One phase involves installing piers to support the concrete perimeter beam. (That beam supports the exterior walls of your home.) The second phase involves adjusting the shallow piers that support the interior of the home. Repairs to wooden beams, joist, and subflooring are made when adjusting interior piers. Because interior piers are shallow, they move seasonally and need periodic adjustments.
Drilled piers are formed by pouring concrete into shafts drilled in the ground. The concrete is reinforced with steel. Drilled piers are the best option for fragile or light foundations.
- Push piers work by being driven deep into supporting soils to provide a firm platform for lifting and supporting the perimeter beam.
Concrete Slab Foundation Stabilization
If your house is built on a concrete slab, repairs are a lot more complicated. There are a variety of methods that can be used, depending on the problems your foundation is having.
- Steel pressed pilings are a powerhouse when it comes to stabilization. This technology revolutionized the industry and is still used today.
- Concrete pressed pilings are made of concrete cylinders. Concrete piers do not work with every type of soil.
- Concrete piers are traditionally how homes are constructed, and thus remain a favorite among engineers. However, they can be cost prohibitive to install.
- Masonry patches and sealants are used when cracks are apparent in the foundation, but no structural damage is done. These cracks are filled with epoxy which fills and seals the cracks.
- High-density polyurethane foam is used to lift the interiors of buildings and is quick to use. It does have a few drawbacks, particularly if it gets into pipes, but is overall a popular repair method.
