Methods for Repairing a Concrete Foundation
Sunken concrete restoration procedures have varied in the past. Wood, concrete, cement, and steel have been poured, pushed, twisted, or otherwise driven into the earth in an attempt to save these foundations and slabs, while in the beginning, everyone and everyone, trained or unskilled, were “experts” at this form of repair. The fixes were frequently ineffective.
Other, more successful, cleanup procedures require substantial disruption of the family or company that uses the building. In most cases, it is preferable to rectify the settling of building slabs and monolithic foundations in residential areas without having to transfer all furniture, appliances, and perhaps the entire family, or to interrupt operations in commercial regions.
However, with today’s technology and experienced professionals, there are a variety of extremely successful solutions to the problem of sunken concrete that cause little or no disturbance to daily life or company operations.
Slabjacking and hydraulic jacking are the two most frequent ways of this sort of rehabilitation (also known as piercing).
A slab jacking process involves pumping grout beneath a slab or beam to generate a lifting force that returns the part to its original height.
Piering involves driving steel posts into unstable soil and using hydraulic jacks to lift or stabilize concrete slabs influenced by changes in the underlying soil. The sort of repair approach employed is determined by the type of distress being addressed.
Selecting the Best Repair Method
You must first establish what is causing the suffering before deciding on a repair procedure. Look for indications in moldings and trim boards, mortar seams in brick veneer, and windows in low locations. Take notice of the recent weather as well. Whether that is unusually dry or rainy might induce movement in the underlying soil.
Slabjacking is the most popular method of repairing smaller slabs of sunken concrete, such as home slabs, driveways, walkways, swimming pool decks, and so on.
Slabjacking is accomplished by injecting cement grout into small, carefully placed holes in the concrete slab. Once in situ, the grout hardens creating a dense concrete mass that serves as a stable foundation for the concrete slab.
If a soil-cement-lime grout is utilized, the lime content of the slurry will provide lime stability advantages to the base or sub-base. This combination treatment not only returns the slab to normal grade but also stabilizes the subsoil, preventing the problem from recurring.
Hydraulic piers are often utilized to elevate and stabilize foundations in bigger difficulties, particularly those encountered in residential and commercial structure foundation displacement.
Piering is strategically placing mechanical jacks to raise the settling beam to grade. To minimize further or unneeded damage, the beam must be gently elevated. After being elevated, the beam is secured in place by a specifically constructed spread footing and pier.
The footing is positioned deep enough to be unaffected by fluctuations in soil moisture. It is also intended to distribute the weight adequately without adding bulk or mass. The pier is steel-tied to the footing and supports the foundation beam.
