Underpinning techniques
We offer a range of underpinning techniques designed to address various foundation issues. Each method is selected based on the specific needs of the project to ensure long-lasting stability and strength.
Mass concrete underpinning
A traditional and reliable method, mass concrete underpinning involves excavating and pouring concrete beneath the existing foundation to reinforce the structure. This technique is particularly effective in improving the load-bearing capacity of foundations.
Mini-piled underpinning
For sites with limited access or where traditional methods are impractical, mini-piled underpinning offers a flexible solution. It uses small, high-strength piles to support the foundation, ideal for tight spaces or sites with challenging soil conditions.
Beam and base underpinning
This technique involves installing a reinforced concrete beam supported by piles beneath the foundation. It is commonly used in areas where additional load needs to be transferred to deeper, more stable soil layers.
Screw piled underpinning
When conventional underpinning methods are unsuitable or difficult to carry out, screw-piled underpinning provides a practical alternative. Helical steel piles are mechanically driven into the ground to stabilise the foundation, making the system well suited to confined sites or difficult soil conditions.
The underpinning process
Our ground beam solutions are designed with versatility and durability in mind, offering a range of features to meet the specific needs of your project. From reinforced ground beams to ground bearing concrete slabs, we provide everything necessary for a stable and reliable foundation, all backed by a 10-year insurance-backed guarantee on our underpinning works.
Initial site assessment
Our team conducts a thorough inspection of the property to assess the extent of foundation issues and determine the most suitable underpinning method.
Customised solution design
Based on the site survey and the structural requirements, we provide a detailed design for the underpinning work, tailored to your project’s needs.
Planning and permissions
We work with local authorities and building control to ensure that all necessary permits and approvals are obtained before work begins.
Underpinning installation
Our experienced team carries out the underpinning work, carefully monitoring each step to ensure the highest standards of safety and quality.
Completion inspection
Once the underpinning is complete, we conduct a final inspection and provide you with a comprehensive report, including details of the work.
Frequently Asked Questions
What is underpinning and why is it needed?
Underpinning is the process of strengthening or stabilising the foundation of an existing building. It is typically required when the original foundation is no longer strong enough to support the structure, such as in cases of subsidence, erosion, or changes in land use.
How much does underpinning cost?
The cost of underpinning varies depending on factors such as the size of the project, the method of underpinning used, and the materials required. Once our experts assess your site, we’ll provide a detailed and obligation-free quotation.
Is the work covered by a guarantee?
Yes, all our underpinning work comes with a 10-year insurance-backed guarantee, giving you peace of mind that your foundation work is protected for the long term. This guarantee can also be extended to 12 years, providing you with extra assurance in our underpinning services.
