What is Underpinning?

Underpinning is a specialised construction process to strengthen and stabilise a building’s foundation. This technique involves extending the foundation to a more stable soil layer or distributing the building’s load over a larger area to enhance its load-bearing capacity.

A foundation’s integrity can be impacted by several things. These include erosion, subsidence, broken services that lead to water saturation, poorly designed foundations, large trees on the property, or even drought conditions. When these problems appear, underpinning becomes necessary to prevent further damage and guarantee structural safety.

The three primary methods of underpinning are:

  1. Concrete Footings: This age-old technique involves building new footings that are deeper than the current foundation to provide stability and limit mobility.
  2. Screw-Pile: This technique uses a more secure soil basis using steel piers next to the current concrete footings. Jacked up to its original position, the building can be sealed up to eliminate any gaps or fractures.
  3. Polyurethane Resin Injection: The contemporary method injects polyurethane resin into the earth around the shaky foundation. Resin’s expanding qualities force the soil to be dynamically compressed and fill spaces beneath the footings, boosting its bearing capacity.

What Does Underpinning Do?

Underpinning serves several critical functions in enhancing the stability of a building.

It reinforces foundations. Underpinning offers additional support to the structure by either increasing the depth of the foundation or enhancing the quality of the soil beneath it. To achieve this, the area surrounding the foundation is typically excavated to reach a more stable layer of soil. This allows for the installation of new underpinning footings. Methods such as traditional concrete underpins and conventional mass techniques offer strong and permanent solutions to support the structure.

It reduces the risk of further subsidence. Underpinning is applied to the foundation to stabilise it and prevent further settlement or sinking of the building. This is accomplished by treating the underlying reasons, which may include erosion, poorly compacted soil, or housing subsidence. Because of this, not only is the structure guaranteed to be stable over the long term, but it also helps to prevent the need for more comprehensive and expensive repairs in the future.

It closes cracks and gaps. Methods such as screw-piling allow the building to be jacked up, effectively closing any cracks and gaps that may already be present in the structure. This essential step restores the structure’s structural integrity and ensures the property owners are satisfied with the end result.

It improves the load distribution. By redistributing the load over a larger area or onto more competent ground, underpinning ensures that the foundation can bear the weight of the building more effectively.

Why Do You Need Underpinning?

If you’re wondering whether your home or building might require underpinning, there are several signs to watch for. To start with, look out for visible cracks in walls, gaps around doors and windows, and unlevel floors—these are all common indicators of sinking foundations.

Other red flags include sloping or uneven floors, noticeable movement or tilting causing structural issues, and persistent water damage or dampness in the basement. These issues can significantly weaken the foundation, making underpinning projects essential to restore stability.

Addressing these issues early is essential for the safety and stability of your property. Ignoring them can lead to more extensive and expensive repairs down the line. And trusting your underpinning to professional repair specialists guarantees that the foundations of your home or property will be strengthened effectively, leaving you happy with the result of your underpinning job.

The benefits go beyond stability, too. Proper underpinning can also increase the value of your property by ensuring it’s structurally sound and safe. Plus, it provides peace of mind knowing that your property is secure from future settling or shifting, preserving your investment for years to come.
