Slab Foundation Repair Methods

Several methods can be used to repair slab foundations, depending on the nature and extent of the damage. Here are some common techniques used in Columbus:

Slab Jacking

Slab jacking, also known as mudjacking, involves pumping a mixture of cement, sand, and other materials under the slab to raise it back to its original position. This method is effective for addressing settlement issues and filling voids beneath the foundation. The process involves drilling small holes in the slab and injecting the mixture through these holes. Slab jacking is a cost-effective solution for minor to moderate settlement problems.

Piering

Piering involves installing concrete or steel piers beneath the foundation to provide additional support. There are several types of piers, including:

1. Concrete Piers: These are poured concrete columns that extend down to stable soil or bedrock.
2. Steel Piers: These are driven into the ground using hydraulic equipment until they reach a stable load-bearing stratum.
3. Helical Piers: These have screw-like blades that allow them to be screwed into the ground.

Piering is a more invasive but also more permanent solution for significant foundation settlement or instability.

Crack Injection

Crack injection involves filling cracks in the foundation with epoxy or polyurethane foam. This method is effective for sealing cracks and preventing water from entering the foundation. It is commonly used for both structural and non-structural cracks. The process involves cleaning the crack, injecting the epoxy or foam, and then sealing the surface.

Underpinning

Underpinning involves strengthening the existing foundation by extending it deeper into the ground. This method is used when the existing foundation is not strong enough to support the structure or when the soil beneath the foundation is unstable. Underpinning can be done using various techniques, such as:

1. Mass Concrete Underpinning: This involves excavating sections of the foundation and pouring new concrete beneath them.
2. Beam and Base Underpinning: This involves installing a concrete beam beneath the existing foundation and supporting it with concrete bases.

Underpinning is a complex and costly solution but is necessary for severe foundation problems.

Surface Repairs

For minor surface cracks and damage, surface repairs may be sufficient. This involves patching the cracks with concrete or epoxy and applying a sealant to protect the foundation from moisture. Surface repairs are typically used for cosmetic issues and do not address underlying structural problems.
