Poor soil structure is a key cause for most failures in foundations worldwide. This has made it desirable to design various methods that can be used to correct such weaknesses. The methods can be used singly or in combination depending on a few factors. Some of the factors based on when picking a method to be used include terrain, soil type, level of damage, climate, and budget. To find the best methods and companies that do foundation repair Fernandina FL is worth being prioritized on a search list.
Slabjacking, steel piling, pressed piling, Pressed pilling with inserts, and bell bottom pier are among the foundation repair method in use today. The last four techniques are grouped together as pierring methods. The reason for that name is that they lift slabs through installation of bars. Before using bell-bottom method, soil is analyzed up to 18 feet in depth. Strength and soil moisture condition are the main factors determined by the research.
The concrete piers are driven into the earth up to a depth where stable soil layer exists. The soil condition and size of home are based on when customizing the size and depth of each pier. The piers are prevented from further sinking by placing two steel rebar at their tips.
The project supervisor makes a report about the position and angle of every pier and gives a copy to the homeowner. The report is useful when carrying out repairs in future. The installation process does not involve imposing forces onto the slab and safety factors are incorporated in each pier. The home remains inhabitable for at least a period of two weeks to allow the piers to dry. However, once the piers dry well, heavy household appliances can be moved into the house without worrying about 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.
One of the advantages of slabjacking is that the homeowner does not need to remove home items from the house when repairs continue. In addition, slabs require no time for drying. This method can also be used in various climates and on different soil types.
