Foundation Repair Methods

So your home has doors that don’t close properly, cracked walls, jammed windows, or bulging floors? Wonder what all these problems actually indicate? Well, these can be the warning signs of foundation problems. Fortunately, there are numerous proven and useful ways to repair a foundation. While some of these methods involve the latest technology, others have been delivering the desired results for years. 

The two major categories of foundation repair are discussed below:

Deep Repairs

Commonly known as underpinning, these repairs involve steel piers that are screwed or pushed into the ground. Once set, these piers lift the foundation’s structural components. They are usually used to lift concentrated loads or bypass unstable soil layers that tend to cause issues with a foundation. 

While performing these repairs, the weight of your foundation may be moved to another layer of ground. A few common deep foundation repairs are as follows:

Push Piers

Also known as resistance piers, these are one of the most common techniques used to repair a foundation. In this process, steel piers are hydraulically pushed into the ground so that the entire weight of your home’s foundation can be transferred to a different and more stable soil layer.

Helical Piers

These are driven into the ground in order to relocate your foundation’s weight to another layer of soil. The piers’ rings or helices play a vital role to keep the foundation stable while its weight is being transferred.

Concentric Push Piers

These are used in limited access or low overhead environments. Similar to conventional push piers, concentric push piers are installed directly beneath the foundation. However, they involve shorter sections of piers. 

Shallow Repairs

If your home’s slab-on-grade foundation has moved or settled, you may need shallow repairs to get it repaired. These repairs may serve you well if you intend to lift non-concentrated loads. When it comes to repairing slab foundations, shallow repairs prove to be a more reliable and economical option than deep repairs. Some common shallow repairs are as follows:

Slab Jacking

This is used to lift and give support to concrete slabs. In this repair process, sand-based grout is injected beneath the foundation to fill cracks and voids and lift the concrete.

Foam Jacking

This is used to repair and raise slab segments of foundations. You can use foam jacking for interior floors. Foam jacking pushes repairs the foundation and pushes it into its original position by injecting high density polyurethane under the concrete.
