Screw piles are a quick, easy, quiet and clean alternative to traditional concrete foundations.


Good for Clients, Neighbours & the Environment



Using screw piles means the removal of excavated soil from the site is virtually eliminated, as is the need to bring in large quantities of concrete.

This means:
• Less noise, mess and machinery
• Vibration Free Installation
• Faster Installation
• Cost Savings
• Eco Friendly
• Reduced Risk to Adjacent Structures

The SipBuild Screw Pile Service is also available for builders to use for their own projects, including underpinning and anchoring solutions to foundation problems across a diverse range of building and construction projects.

Screw Piles are suited for situations requiring compression and/or tension loads. Screw piles are currently being used for loads up to 150 tonnes and lengths up to 30 metres.

Typically, traditional excavating equipment is used to install screw piles and common construction equipment can, at low cost, be modified to install screw piles. This means lower site establishment costs than specific piling machinery.

History of Screw Piling

The screw pile was invented by the blind English brick maker, Alexander Mitchell, in 1833.
The first screws were made of cast iron and were used to build lighthouses exposed to moderate seas or heavy ice fields.
The shafts were from 3 to 8 inches in diameter with the helix from 18ins to 5 foot in diameter! They were screwed down from 10 to 20 foot into clay, sand or coral, by about 30 to 40 men, pushing with 6 to 8 capstan bars, the ends of which circled an arc of 30 to 40 feet in diameter.

The first such structure was constructed on Maplin Sound at the mouth of the Thames in 1838. The first screw pile lighthouse in the United States was erected in the Delaware Bay on Brandywine Shoal and was completed on October 28, 1850. Since then Screw Piles are becoming the preferred choice of deep foundation system for a growing number of applications.
