Cast pile

driven-pipeconcretereinforced concrete

TreviI piles belong to the category of cast in-situ driven piles, in a previously driven pipe form, driven without extracting the soil. Their special feature is their expanded concrete base or bulb at the bottom and along the piles surface there is a series of protrusions with dimensions that are inversely proportionate to the resistance of the surrounding soil. Due to these features and the compacting effect on the soil while the pipe form is being driven, these piles considerably improve the subsoil’s load-bearing capacity, and in contrast to other types of deep foundations, can be calculated as an element resting on an enlarged base of an area greater than that of the shaft. Trevi piles are made with modern machinery that makes it possible to reach depths of 25 m with a 350-600 mm diameter and with slopes of up to 18°.
