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.

Where to start?

When planning your project, it’s important to make smart choices. If your project has a heavy load, it may require bigger and deeper piles, which can cost more money. We recommend making your construction as light as possible to save money. You can do this by using materials like steel frame ring beams, lightweight steel floor joists, and different coverings like brick SLIPs, timber, or cement board for lighter buildings. But if your project is really heavy, we offer services like reinforced footings, poured concrete, and special suspended concrete floors using blocks and beams.
