Underpinning is an important process that is often overlooked during the construction process. Because of this, it’s in your best interest to be as informed as possible about underpinning. To make things more manageable, we thought it would be helpful to put together a brief article about this subject. If this is something that you want to learn more about, read on as we break down everything you need to know about underpinning. Given the broad scope of this topic, we’ve decided to split this article into two parts.

What is Underpinning?

Underpinning is an important and often overlooked element of construction projects. It is a process that involves strengthening the foundation of an existing structure, often involving the excavation and replacement of materials. This process is used to improve the structural integrity of a structure and provide additional support for a building or other large structure.

When is Underpinning Needed?

There are many reasons why a home or other structure might need underpinning. The most common reason is that the original foundation was not built deep enough, or that the soil it was built on is not stable enough. Over time, this can lead to cracks in the foundation and other problems.

Underpinning can also be used to stabilize a structure that has been built on a hillside that has since eroded. This can help to prevent the structure from sliding down the hill.

In some cases, underpinning may be necessary to repair damage that has already been done to a foundation or to stabilize a structure that has become weakened due to age or construction defects.

No matter what the reason for needing underpinning, it is important to have the work done by a qualified and experienced contractor. This type of work can be very technical and complex, so it is not something that should be attempted by a do-it-yourselfer.

How Does Underpinning Work?

The underpinning process typically involves excavating beneath the existing foundation and replacing the soil with a stronger material. This material can be concrete, steel, or other materials that provide structural support. The materials chosen will depend on the type of soil, the size of the structure, and the amount of support required.

One of the most common methods of underpinning is known as “pile and beam” underpinning. This method involves driving steel or concrete piles into the ground to support the foundation. Once the piles are in place, a beam is placed across the top of the piles to provide additional support.

Another common method of underpinning is known as “slabjacking.” This method involves pumping concrete or other materials under the foundation slab to raise it to the desired level. Slabjacking is often used to level a foundation that has settled unevenly. 

No matter which method of underpinning is used, the goal is to provide additional support for the foundation so that it can better support the weight of the home. This can help to prevent foundation problems such as cracks, settling, and unevenness.

Underpinning is a complex process, requiring skilled professionals and specialized equipment. The process typically involves excavating to a depth below the existing foundation, then installing and securing the new foundation materials. In some cases, additional supports may be required to ensure the structural integrity of the building.

Because of the complexity and technical nature of underpinning, it is important to hire a professional contractor who is experienced in the process. The contractor should be familiar with local building codes and regulations, as well as the type of soil and other conditions that may affect the success of the project.

Conclusion

Underpinning is an important part of many construction projects, and a professional contractor can help ensure that the job is done correctly and safely. If you’re considering a project that involves underpinning, be sure to hire a qualified and experienced contractor who can provide the best possible results.
