Screwpiles sometimes referred to as steel screw-in piles, screw piers, helical piers, screw piers, screw foundations or screw piles have been around for many years. Their first reported use dates back to early 1800's where they were manufactured from cast and wrought irons. In latter years the concept was picked up by companies that manufactured cast iron helical pilots that were connected to various carbon steel shafts to produce a range of compression/tension piles.
The STG group are Australian pioneers, introducing screwpiling technology to Western Australia in 1996. Our R&D has expanded the technology from a small ground piling/anchoring pile primarily used in reactive clay (black) soils into a screw piling system that is considered performance predictable and the most cost effective hi-capacity compression pile and ground anchoring system available today.
Screwpile load carrying capacities now exceed 2000kN and can generally be installed in a matter of minutes. Years of continued R&D has developed a piling system that is rapidly becomming the preferred instant foundation method for innovative engineers and builders and years of successful installations and the proven performance has seen our systems embraced by structural and geotechnical engineers.
With over 15 years of technological expertise Screwpile Australia is consulted Australia-wide to design cost effective sub-foundation and ground anchoring solutions. With additional expertise from its associate structural engineering consultancy firm Foundation Engineering Pty Ltd and the groups aquisition of specialist microfine grout soil injection and soil stabilisation company FONDEX a much wider scope of foundation solutions is now available.
In recent years our associate company Rapid Anchor Pty Ltd patented composite helical technology for small screwpiles. Testing results show significant improvements in anchor holding capacity over its steel counterpart. Rapid Anchor now mass produces registered and trademarked retail products such as the Wombat and Octopus.
