What are the different types of Home Foundation Repair?
A foundation is a fulcrum on which a house sits. This foundation holds the house in place. For a house to be strong, first, the foundation has to be perfect.

Foundation Types
There are two prominent types of foundations. First let us consider the slab-on-grade foundation. A simple concrete slab is poured below the structure to give it a strong base. It is purported to give the structure solid flooring. It can move as one structure. It won’t get fragmented. This is a shallow foundation that will often shift from season to season as it is impacted by seeping water an also by the root systems of local plants. Slab-on-grade foundations are akin to the root systems of grass or shrubbery.
Another type of foundation usually employed is Pier and Beam foundation. They are deeper. They can be used in areas where snow and frost fall. It will sink below the frost line. This type of foundation can include a basement. The frost line is generally located between 5 and 8 feet below the surface. These types of foundations are always used in residential and commercial properties. The guidelines for using the foundation are decided by the period and style of the building besides the soil conditions and the requirements of the property owner.

Advanced methods of foundation repair
According to Jeffery Ellison, an acclaimed expert in repair construction, there are three advanced methods of foundation repair – concrete press piling, steel press piling and bellbottom piers. Bellbottom piers before the hydraulic depress piling systems were invented. Steel piling is employed for soft clay called Caliche. The concrete pilings are 6 inches in diameter whereas the steel pilings are less than 3 inches in diameter. Compared to concrete pilings, they can penetrate more through the stiffer soils.

Steel pier method
The steel pier method is rated as the best of the lot. Due to its long lasting support factor. According to Granite Foundation Repair, the robust steel pier is drilled into rocky terrains at pressures of up to 10,000 PSI and depths up to 60 feet. Normally, the type of foundation repair takes three days to get completed. Pressed pilings are graded as the quick solution. The pre-arranged pilings mated with a solid combination of steel and concrete. The pilings are hydraulically drilled by employing an installation force of 5000 PSI. This operation will acquire support strength of twice its installation force in a short period owing to the soil mechanics of friction and compression. As per website, “The system consists of pressed concrete pilings topped with a pier cap, blocks and shims”.
Another economical foundation repair is drilling or pouring concrete piers. This is performed by drilling holes to depth of 9 to 12 feet below the surface and then filling with steel and concrete. Concrete which has been poured is added with concrete spacers and shims. At the initial stage, a structural engineering company has to be pressed into service for testing the soil. They will recommend which foundation would be the most suitable for that particular soil. After the initial formalities the engineer can decide on the design of the specific slab for the evolving soil conditions. As Ellison quotes, many persons don’t resort to this operation as they are reluctant to make any extra payment. Even though the house owner pays a maximum amount of $800 to obtain the service of any qualified and efficient engineer, that is a worthy expenditure considering the long term prospects.

Options for foundation repair
When it is a question of foundation repair for your house, you have to consider many options. They range from using helical piers or steel push piers, water-proofing or underpinning, concrete-segmented piles or steel push piers besides eccentric vs. concentric piers. Some people will support certain decisions and some other voices will speak negative sentiments about some functions. By sifting the worthy reasons from unacceptable reasons and proceeding with your goal is the key to success for all endeavors including foundation repair.
Now, you can start the process by getting in touch with bright engineers who know the ins & outs of their profession.
