Full Displacement piles are bored cast in situ
concrete piles constructed by advancing a
displacement boring tool into the ground with
a rotary drilling rig using both torque and
crowed force.
The technique is ideally suited for a wide
spectrum of soil condition ranging from
sandy gravel, sand, silt and clay to soft
organic soils, so long as the soil is displaceable.
The particular advantage of Full Displacement Pile is the relatively simple technology
where no temporary casings are used.
While the full displacement auger is screwed
into the ground with the lower opening
plugged by a bottom plate the soil gets completely displaced and thus compacted.
The boreholes stays dry without any excavation is taking place. This silent and vibration
on free drilling method is highly suitable for
jobs where the existing ground water table
cannot be disturbed or if the soil is contaminated and an exchange of the contaminated
fdP Standard: a hollow steam auger
displaces the material of the pile diameter
laterally into the adjacent ground,
after reaching final depth, the auger is
retracted (it is rotated in drilling direction)
whilst simultaneously concreting through
the hollow stem and subsequently the
reinforcement cage is installed using a
vibrodriver.
FDP tool can be manufactured as one piece
or in two parts so that with an extended
starter auger is possible to drill through
thinner non displaceable formations.
