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 widely used to repair foundations include pressed pilling with inserts, bell bottom pier, steel piling, pressed piling, and slabjacking. The name pierring is a collective term given to the first four methods. This is because they all employ steel bars to lift slabs up to the right position. The soil is normally researched to a depth of 18 feet when the bell-bottom method is to be used. The research is meant to determined moisture condition and strength of the soil.
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 has a worldwide reputation for being a good method for repairing slabs. It is different from pierring because no piers or bars need to be installed under the slab. The method however involves pumping of concrete under the slab to fill voids causing subsidence in the slab. The concrete is pumped through holes that are drilled into the floor.
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.
