Foundations are sometimes prone to damage especially if the soil structure is not good enough. As such, there are several methods designed for correcting weaknesses in foundations and restoring them to the right condition. The choice of method is normally dependent on several factors including soil type, climate, terrain, budget, and level of damage already done. For the best foundation repair Fernandina FL offers one among the best places to consider visiting.
The various methods available for foundation repair include bell bottom pier, pressed piling, pressed pilling with inserts, steel piling, and slabjacking. The first four methods can be collectively classified as pierring methods. They all involve using steel bars to raise the slab back into position. When using bell bottom method for repairing, the soil is first researched to a depth of about 15-18 feet. The research aims at determining the moisture condition and strength.
The concrete piers need to be pushed underground until they reach a hard soil layer. Each pier is customized in size and depth depending on soil type and size. Two steel rebar placed on top of every pier prevent them from subsiding further underground.
The angle and position of every bar is documented in a report, which is left with the homeowner. The report can become useful in future repairs. Safety factors are designed into each pier and no forces are exerted against the house during installation. The piers need at least two weeks to dry before the home can become usable again. However, once the drying period is over, one can move heavy household appliances into a house without concerns for the foundation.
Precast concrete cylinders get installed underneath the residence in pressed piling technique. Holes into which the cylinders are installed are dug under the foundation first. Once the installation is through, the cylinders are driven further into the ground using the weight of the home. Houses in areas with weak soils should not be repaired using this method as recommendation by experts. This is because, when the soil is weak, the cylinders may end up being driven too deep than they need to.
The cylinders are also vulnerable to horizontal earth movements because they are not secured together. Also, broken cylinders may go unnoticed during the installation process, leading to failure after a short time. Slabs may also get damaged further by this technique.
Slabjacking is a method that is also commonly used for repairing slabs in many places worldwide. Unlike pierring, it does not involve installation of piers or bars into the soil beneath the slab. However, it involved pumping concrete under the slab to fill any voids that are causing the slab to subside. Holes need to be made into the floor of a home to provide the way through which the concrete is pumped.
The advantage with this method is that one does not need to move out of the house during the repair. In addition, the slab does not need time to dry before the home can be usable. This method is applicable in most soil structures and climatic conditions.
