DPA PLUS screw piles form part of a cast-in-situ soil displacement screw pile system. The soil is pushed to the side so only a little of the disturbed soil can enter the casing.
It is a low-vibration process, which is important where piles are installed close to adjacent walls that could easily be damaged by subsidence and/or vibrations, as is the case at this building site. DPA PLUS screw piles are particularly suitable for residential construction, non-residential construction and other new-build projects where it is necessary to limit nuisance or disturbance in the immediate vicinity. As a result, they are very good for urban-regeneration projects: low in vibrations and noise pollution compared with driven pile systems.
