Screw-piles are removable and re-locatable with buildings. The site preparation needed is minimal, with little or no concreting required. This allows for faster installation of buildings and again makes them an environmentally friendly alternative.
Re-locatable building projects that screw-piles have been used in include temporary relief buildings at Innisfail following Cyclone Larry, Kowanyama Ambulance Station, temporary accommodation at Gracemere Mine Site and ranger stations and housing on Fraser Island.

Geotechnical reports indicated the site contained laminated sandy clays and alluvial fill overlaying weathered sandstone. We installed over 300 screw-piles to depths of up to 17 metres and ranging from 100kN to 300kN SWL.
Screw-piles are ideal for bridge foundations and abutments. The installation process provides for speedy job completion with ease of access and minimal disturbance and spoilage. Screw-piles were used in the restoration of bridge approaches at Abergowrie Bridge Cutting, via Ingham following major flooding. This required the installation of 38 screw-piles installed horizontally at 400kN tension - installation time was 12 hours.
