Screw piles are designed to have single or multiple discreet flights with dias. up to 900mm and are a sacrificial pile installed with a hydraulic head on a machine. Spiral Drillers has over 12 years experience in installing Screw Piles.
The benefits of these piles are that there is no spoil removal from site, therefore they are good in contaminated ground and can be easily spliced to go deeper if required.
Site testing can be carried out on piles once they are installed to achieve correct loadings.
