What is Underpinning?

Foundation underpinning is a repair solution often used to restore a foundation’s strength. As time passes, like everything, buildings undergo physical changes. These might be planned changes, like adding additional floors to a structure, or unplanned changes, like a weakened foundation due to settlement or excess moisture.

Regardless, if your foundation is no longer strong enough to support the building’s functions, underpinning might be your solution. Our team understands the wear and tear that your structure has likely sustained and can point you towards the right foundation repair solution, so your building operates for many more years of business!

What is underpinning used for? 

Underpinning can be utilized in the following situations: 

  • Raise foundations impacted by settlement
  • Increase load capacity of building’s foundation (especially in the event of adding levels)
  • Repair and restore strength to damaged foundations

Elements That Impact Commercial Structures

Many factors can lead to the deterioration of your building’s foundation. Our team can assess yours to see if underpinning and foundation repair can provide a viable, long-lasting solution. Some of the elements that can negatively impact your structure include:

  • The original foundation has lost strength and stability over time
  • Structure usage has changed
  • The soil beneath the structure may have been affected by subsidence
  • Excavation of soil may be necessary due to new constructions nearby
  • The need to increase the load capacity of existing foundations arises

The Underpinning Process

The most common sign that your building may need underpinning is when cracks are visible in your foundation. There are several different foundation underpinning methods to choose from, and our team is experienced at recognizing the most efficient method for each individual project.

Underpinning is the process of extending the foundation in depth or range so that the weight of the foundation is distributed more evenly and is better supported. The most standard method of foundation underpinning is called the ‘mass pour method’ – excavating sections of your foundation in a predetermined order by pouring concrete into each section to widen and deepen your foundation.

Another popular option for underpinning is the ‘screw piles and brackets’ method – using piles inserted into pre-drilled holes for additional support for your foundation. This method is more practical in situations where there is limited access or if there is a need for a deeper foundation, making the mass pour method unserviceable. 

Underpinning can provide your building with the support and stability it needs to last for generations to come. United Dynamics has provided this service to thousands of satisfied customers, and we’re ready to help you.
