Screw piles are designed to have single or multiple discreet flights with diametres up to 900mm and are a sacrificial pile installed with a hydraulic head on a machine. Spiral Drillers has been installing screwpiles since 2005.
The benefits of these piles are that there is no spoil removal from site, and great for ground that collapses while drilling, as well as being great in contaminated ground and can be easily spliced to go deeper if required.
Site pile testing can be carried out after installation to ensure loading capacity is reached.
