Rotary Displacement Piling

Rotary displacement piling systems provide improved soil strength, pile capacity and load transfer to the surrounding ground.

The technique also offers a reduction in overall foundation costs by reducing pile lengths and diameters and most significantly, substantially reducing/eliminating the cost of pile spoil disposal.

As the boring tool penetrates, soils are displaced resulting in a localised, increased relative density and strength around the pile (depending upon soil conditions). Minimal spoil comes to the surface.

Improved load transfer to the surrounding ground is achieved through an enhanced shaft capacity. Thick concrete threads are created in the construction process that facilitates the load transfer from pile core to soil. This is achieved through the creation of an increased diameter/surface area and the bearing effect of the thick threads formed.

Minimal spoil at ground level provides an ideal solution for Brownfield sites where contamination may be an issue.
