Underpinning

Screw piles for underpinning is an alternative method giving significant advantages.

1. Safety: Using screw piles reduces risks to the workforce and the existing structure, making it a safer option.
2. Earth Removal Reduction: Screw piles minimise the amount of earth that needs to be removed during the underpinning process, and in some cases, up to 85% of the excavated earth can be reused and compacted.
3. Landfill Reduction: By reusing excavated earth, screw piles contribute to reducing landfill waste.
4. Disruption Minimisation: The underpinning process with screw piles results in less disruption, making it a more convenient option for both homeowners and neighbours.
5. Cost Reduction: Reduced excavation and earth disposal costs, coupled with shorter project timelines, can significantly lower overall project costs.
6. Environmental Impact: Screw piles have a lower environmental impact compared to conventional underpinning methods.
7. Pre-Compression: The unique feature of pre-compressing the piles under the footing using hydraulic jacks (up to 8 tons) pre loads the pile giving instant support compared to other methods that will settle.
8. Access Flexibility: The system’s adaptability allows installation equipment to be brought through the front door if necessary, ensuring accessibility even in constrained spaces.
9. Reduced Project Duration: In some cases, using screw piles for underpinning has reduced the project duration from the conventional 6 months to just 1 month, eliminating the need for clients to move out.
