The Solid Foundation: Benefits of Underpinning with Helical Screw Piles for Rectifying Subsidence

Updated: Oct 10, 2023

When the ground beneath your home begins to shift, it can cause serious structural issues and, in some cases, subsidence.


Subsidence is the gradual sinking or settling of the ground, which can lead to cracks in your walls, uneven floors, and a host of other problems. If you're facing subsidence issues, it's essential to address them promptly to ensure the safety and stability of your property.


One highly effective method for rectifying subsidence is underpinning with helical screw piles. In this blog post, we'll explore the numerous benefits of using this innovative technique to restore your home's foundation.


Understanding Underpinning with Helical Screw Piles

Before delving into the advantages of this method, let's first understand how underpinning with helical screw piles works.


This process involves installing helical screw piles deep into the ground beneath the affected area of your foundation. These screw piles are designed to anchor the foundation securely to load-bearing soil or bedrock.


Essentially, they provide additional support to counteract the effects of subsidence.

Benefits of Using Helical Screw Piles for Subsidence Rectification

  1. Cost-Effective Solution: Underpinning with helical screw piles is often more cost-effective than other foundation repair methods like concrete underpinning. The installation process is quicker and requires less excavation, which can translate into lower labour and material costs.

  2. Minimal Disruption: Traditional underpinning methods can be disruptive to your daily life, requiring extensive digging and excavation. Helical screw piles are installed with minimal disruption to your property. This means less mess, less noise, and a quicker return to normalcy.

  3. Speedy Installation: Helical screw piles can be installed in a relatively short amount of time, allowing you to address subsidence issues promptly. This is particularly important for minimising further damage to your home.

  4. Environmentally Friendly: The installation of helical screw piles has a lower environmental impact compared to concrete underpinning, as it generates less waste and requires fewer materials. This makes it a greener choice for foundation repair.

  5. Increased Structural Integrity: Helical screw piles provide robust support to your foundation, effectively stabilising it against further subsidence. This not only prevents future damage but can also improve the overall structural integrity of your home.

  6. Versatile Application: Helical screw piles can be used in various soil conditions, including clay, sand, and silt. Their versatility makes them suitable for a wide range of subsidence scenarios.

  7. Longevity: Helical screw piles are made of durable materials like galvanised steel, ensuring they have a long service life. Once installed, you can expect them to provide reliable support for decades.

  8. Minimal Maintenance: Unlike some other foundation repair methods, helical screw piles require minimal ongoing maintenance. This means you won't have to worry about regular inspections or repairs, saving you time and money in the long run.

Dealing with subsidence can be a stressful and costly experience, but underpinning with helical screw piles offers a practical and efficient solution.


From its cost-effectiveness and minimal disruption to its long-term benefits and environmental friendliness, helical screw piles prove to be an excellent choice for rectifying subsidence issues.


By choosing this method, you're not only restoring your home's foundation but also ensuring the safety and stability of your property for years to come.


Don't let subsidence undermine the value and safety of your home; opt for helical screw pile underpinning and enjoy the peace of mind that comes with a solid foundation. Contact us to see how we can help with your project.
