Bored Piles
Large diameter bored piles
of concrete or reinforced
concrete are an economical
means of supporting high
structural loads with
minimum settlement.

Piles are a powerful, state-of-the-art construction element with many applications in civil
engineering and building. As contiguous, or secant pile walls in water bearing soils they
are used to secure deep excavations or retain slopes. In piled foundations they are used
at various diameters as single piles or pile groups.
Depending on the application, all bores are either concrete filled (with or without
reinforcement), or filled with removed spoil. Occasionally steel sections are inserted as
plunge columns or in cases of high lateral load.

Construction methods
Kelly bored piles
FOW Drilling
We can install Kelly piles
using augers or core
barrels in the common
diameters 620, 880,
1180 and 1500 mm.
The piles can be
installed to depths
of up to 40 m either
vertically or inclined,
with casing, or with
suspension support.

piles with diameters of
406 or 508 mm can be
executed to a depth of
up to 12.5 m – allowing
work close to buildings
or walls.

Continuous Flight Auger Drilling
We execute CFA
(continuous flight
auger) piles with
diameters of 430,
550, 630 and
880 mm to a depth
of up to 26 m.

Large diameter bored piles usually
have to withstand high loads, and we
therefore use a variety of qualityassurance methods for our products.

Applications
1 Foundations
Large diameter bored piles are particularly
effective in transferring high loads. They are
thus excellently suited for foundation works in
nearly all types of soil.
Integrity testing
2 Stabilisation of excavation pits
In inner-city areas it is essential that the spaces
between buildings are fully utilised. Piled walls
are an established method of retention on the
boundary or close to adjacent buildings. They can
be combined with other geotechnical solutions
such as Jet Grouting to form near water tight pits.
3 Slope Stabilisation
Slope stabilisation is necessary to prevent
landslides and protect existing buildings and
structures. Here, large diameter bored piles
are regularly used often combined with other
techniques such as ground anchors or soil nails.

4 Infrastructure
Whether in tunnelling, in road or bridge
construction or in measures for flood
protection, large bored piles can be used in
a multitude of ways and are often found in
infrastructure projects.
