Screw Piers

Fixed priced quotes: Do you have Engineers, Architectural and Soil report? Through a soil test (Geotechnical report ), we investigate the various soil layers to identify the depth suitable to achieve the Safe Working Load specified by your engineer for each screw pier.To obtain a competitive price enquire today

The install process : Installed on site with an excavator, we attach the head of the screw pile to a hydraulic auger and rotate the screw pier through the various layers of soil until we reach a target depth and torque. Placement, depth and torque read outs are then recorded in a report to be analyzed by an engineer for compliance.

The Benefits

  • Suitable for housing, commercial and industrial projects
  • Saves you time and money
  • Quoting made simple with fixed price quoting (No surprises)
  • No more having to remove tones of spoil / soil
  • Greater depths achieved with ease
  • Less heavy machinery on site
  • In detail report provided at the end of every job
  • Engineering compliance certification provided at the end of every job

What are screw piers?

Screw piers or screw piles are a great alternative to using concrete piers.

Screw piles transfer building loads through a shaft (350 grade CHS section), to a helix plate, which is located at the bottom of the shaft.

The size of the shaft and helix will vary in diameter and thicknesses to achieve the ultimate load capacity specified by the engineer.

Screw piers or screw pile can be designed to allow for all design loads and geotechnical conditions as per your project.

Manufactured with 350 grade steel - Screw Piers are long steel tubes with a single form helix at one end which is screwed into the ground. The other end, which sticks up from the ground, is capped with a circular platform on which the concrete slab or footing for a building structure rests. Screw piers are usually made of high tensile steel. This material provides the strength needed to hold up the structure as well and prevent them from buckling and twisting.

Advantages of screw piers

Screw piers can be installed quickly and efficiently, as they don’t require pre-dug holes, there is no booking concrete, no waiting for concrete pumps to arrive and no spoil to remove.

Meaning you can keep the job moving as soon as the piers have been capped. This can provide a significant time and cost advantage on installation, screw piers can be used just about anywhere an excavator will fit. They are especially popular today due to the ease of Instillation, and limited clean up required.

How do we install screw piers?

Our team is specialised in the installation of screw piers and we do most residential jobs within four to five hours. Our team inspects the site, mark the site for pier placement and then place piers in position and complete the install.

We do this by attaching the pile in place to a hydraulic drive motor connected to an excavator. We then monitor the instillation of the pile to record torque readings, pile depth and the strength of the pile in a report.

That report will be then sent to a engineer to be checked for compliance along with site photos to provide evidence of placement position.

Pros of using a screw pier

There are many advantages to using a screw pier compared to traditional concrete piers. Some of the advantages of screw piers are as follows:

  1. Installation is much faster than old fashioned driven or board piles.
  2. No secondary reinforcement material or concrete needed
  3. 3. Ideal for all types of surfaces and soils, including contaminated ground, and deep sand as they are easy to extend
  4. Greater depths achieved with ease
  5. 6. They are easily measured for depth - Great for Sewer Inspectors as they no longer have to be on site when piers are being installed - They can attend site and measure the depth after the instillation
  6. Safer - No more worrying about workers falling into open holes
  7. In detail reports at the end of every job
