The GroutForce™ displacement pile (GDP) is a patented foundation solution for loose to dense sand or soft to firm clay which can provide axial capacity of over 500 kip (2224 kN) as well as significant lateral capacity. Since the grout column increases diameter and frictional bond, the shaft length may be reduced by 50% or more versus other pile types. The displacement casings and plates create a uniform, continuous-diameter grout column. Unlike some other displacement pile products, you can expect a full-diameter grout column with GroutForce.
