Differential foundation settlement repair options

The good news is that differential settlement-caused home moving is frequently repairable. To put it another way, most foundations do not need to be updated. The four most prevalent Foundation Repair Santa Monica procedures are discussed here. Check out our service pages for additional information on each one.

The primary reason for foundation displacement is that the structure was built on poor or unstable soils. It might also be related to dry conditions causing clay soil to shrink or erosion problems.

Piers of resistance

Resistance piers are sometimes known as push piers. They’re built of heavy-duty steel and are forced into the load-bearing earth by the building’s weight and hydraulic pressure. At that time, hydraulic jacks are installed on top of them to elevate the structure back to its original position.

Resistance piers are hydraulically driven high-strength steel tube end-bearing piles. The pipe diameters range from 2-2/8″ to 4-1/2″, as do the steel thicknesses and transfer brackets, to meet a broad range of load and support circumstances. The most usual size is 2-7/8th, however, the size of the pier should be decided by the weight of the structure, the spanning capacity of the foundation, and the soil beneath the residence.

Helical pilings

Helical piers acquire their name from their helical form, which is twisted down into the load-bearing soil. The amount of torque required to push them down into the earth determines their load-bearing capability. Once the piers are in position, hydraulic jacks are used to bring the structure back up. A helical pier is a steel foundation pin with helices, similar to screws. A hydraulic system drives it into the soil to depths below the frost line. Helical piers are used to support structures, particularly in areas where soil conditions are difficult to establish a typical foundation system. Instead of massive, costly excavations, they drill down into the ground. They are also utilized to fix old foundations that have issues like cracks or are weak. Helical piers reduce the amount of time required to establish a foundation, create less disturbance to the soil, and transmit the weight of the structure to soils deep into the ground that will carry the strain.

Piers made of drilled concrete

Homes built on hillsides are prone to differential settling caused by inadequate compaction and soil creep. This issue can be resolved by sinking concrete piers down into the bedrock beneath the foundation.
A big diameter hole is drilled in the earth and then filled with concrete to form a drilled pier. The primary distinction between a drilled pier and a bored piling is size.

Bored heaps are typically smaller than or equal to 0.6m in diameter. Drilled piers are typically defined as shafts bigger than 0.6m in length. A drilled pier is a deep foundation that is designed to transfer large axial or lateral loads to a deep stratum under the ground surface.

Piers on slabs

Slab piers are resistance or helical piers that are inserted through tiny holes in the floor or slab. Anchors are then put into the holes until they reach load-bearing soil. Heavy grade steel brackets are then used to secure the anchors to the slab. Slab piers are occasionally utilized to offer extra support to inner slabs after the foundation is elevated using piers installed around the foundation’s perimeter.
