What Is a Residential Underpinning Foundation?

A residential underpinning foundation is designed to reinforce the structure below a house without tearing it down. Underpinning consists of replacing the bottom layer of soil, followed by the underpinning material. The process is repeated until the entire foundation base is reinforced. If you are planning to install a new home foundation or you want to repair a deteriorated one, you should know more about the residential underpinning foundation process.

Generally, homes are constructed on marginal land with low bearing capacity. Most foundations are based on expansive clay, which shrinks and swells with the moisture content. Underpinning extends foundation support to the deeper levels, where soil conditions are less likely to affect it. Residential underpinning foundation repair is a great solution to a foundation that is prone to settling. The process will stabilize a home’s foundation and make it safe to live in.

Underpinning is most effective when performed on load-bearing walls. It should be done by digging a strip of footing approximately three feet long, two feet wide, and two feet deep. Then, fill the area in the footing with concrete made up of one part cement and three parts sand. A rod bar should be placed inside the cavity to hold the concrete. Once the concrete has set up, it must be cured before the house is loaded or it will break.

Homeowners should contact professional home foundation contractors as soon as they suspect their homes may be in need of residential underpinning. A qualified contractor will carry out a thorough assessment of the structure and have the right equipment for the underpinning project. They will have the knowledge, equipment, and experience to ensure the highest quality foundation repair. It will also eliminate the risk of further damage to your property. The cost of residential underpinning foundation repair is significantly lower than the cost of replacing a whole foundation.

The mini-piled method is another option to consider. This technique is suitable for areas where ground conditions are difficult to access or if the foundation area is not in a position to accommodate it. Mini-piled underpinning involves drilling holes deep enough to rest the piles in stable soil. While this method requires more engineering and skill than traditional underpinning, it can successfully overcome even the most challenging soil conditions. While this process is highly effective, it can also be expensive, as it requires specialists with specialized equipment.

Residential underpinning foundation repair requires several different methods. The most popular ones include drilled concrete piers, helical piers, and resistance pigs. Among these methods, resistance piers are the most common. These piers are end-bearing and don’t rely on skin friction to lift the foundation. For this method, you must consider the location of your house when choosing the type of underpinning.
