Strong But Light Weight

Did you know: Using materials with high mass can add additional weight to an area that is already suffering from subsidence? 

If you choose Polyurethane resins it means you can get the same result as concrete underpinning without the risk of weight impact.

Polyurethane resins are light weight but also very strong. High strength and light weight means no risk of causing the compounding effect you could get from the additional mass of traditional concrete underpinning.

Because resin injection is much faster it means you won’t get held up waiting for underpinning.

Benefits Summary

Here’s why people choose resin injection for underpinning;

  • It’s super fast.
  • Usually no excavation is required.
  • It’s solid (80mpa).
  • The resins have a 50 year warranty.
  • It is versitile and can be used in many underpinning situations from subsidence to foundation jacking & void filling.
  • Resin can be shaped and creatively injected into locations that that concrete  and grout can’t reach.
  • We can inject deeper into the ground than you would normally excavate to get very deep and solid underpinning.

What is Underpinning?

Sinking foundations can jeopardize the structural integrity and safety of a building. 

This occurs when the foundation gradually settles or sinks into the ground, leading to a variety of problems.

Understanding the causes, signs, and potential solutions for sinking house foundations is crucial for homeowners to protect their investment and ensure the stability of their property.

Resin Injection Underpinning is the Fastest and Least Invasive Way to Stop Your Foundations From Sinking.

So Why Do Foundations Sink?

1

Subsidence

Subsidence, occurs when the ground sinks or settles downward. This can happen for various reasons, but it often involves the collapse of underground materials or the withdrawal of fluids from beneath the surface.

Compaction

2

Activities such as construction, the installation of underground infrastructure (like tunnels or sewers), or the placement of heavy structures on the surface can cause the soil to compact over time.

3

Natural Processes

Natural processes such as dissolution of soluble rocks (like limestone), and the natural settling of sediment can cause the ground to subside gradually over time.

Groundwater Withdrawal

4

“subsidence due to groundwater withdrawal” happens when groundwater is removed leading to the compaction and settling of the ground above. This can happen by ground water naturally drying or changes in below ground waterflow or drainage.

5

Water Saturation

Water events can infiltrate and saturate sediment layers, causing them to become softer and more prone to compaction. Over time, this softening can contribute to subsidence, particularly with repeated saturation events.

Erosion

6

Waters can erode soil and sediment from beneath structures, roads, and other infrastructure, leading to voids or empty spaces underground. As these voids collapse or fill with water, the ground above may sink, causing localized subsidence.

7

Neighboring Construction

Excavation for foundations and basements can destabilize the ground. This disturbance can lead to soil compaction and settling, causing subsidence in neighboring properties as the soil adjusts to the changes.

Vibration

8

Heavy construction machinery or newly installed roads can generate vibrations that propagate through the ground. These vibrations can compact loose soil, displace sediments, and disturb underground structures, potentially leading to subsidence over time.
