Design and Construction Of Pile Foundations - Learning Technology

WebbScrew Piling is a construction method used to build deep foundations through the use of ground anchoring which is done by steel screw-in piling. Screw piles are circular and hollow steel screw tubes which hold one or more helices on their outer surface. WebbThe screw pile foundation is a fast and easy method for strong foundations with a wide variety of construction applications. The Helix screw pile is a manually installed pile which uses a crow bar or installation kit. It is especially suitable for small buildings, decking, fences and piers, and has a relatively effortless installation process.
