Piles (CIDH)
CIDH
piles
are used
to support
structures
built on ground that is subject to
movement. The piles are drilled through
the unstable ground layer to more supportive
substrata. Drilled piles are constructed
by first drilling a shaft, then placing
a steel reinforcing cage in the shaft,
and finally filling it with concrete.
D.J. Scheffler, Inc. can drill piles
ranging from 24” to 120” in
diameter. We are equipped to construct piles for single- and multiple-family
residences, high-rise buildings and bridge foundations.
Additionally, D.J.
Scheffler employs the latest drilling technologies
to minimize vibration during construction.
Vibration may cause unstable soils
to settle, thus causing damage to structures
surrounding the job site.

Mini-
and Micro-Piles
Mini- and micro-piles are smaller diameter than CIDH foundation piles. Nevertheless,
they are capable of supporting significant foundation loads. These foundation
elements are constructed similar to drilled piles, except that the reinforcement
is a single steel bar as opposed to an I-beam or re-bar cage. Also, high strength
grout is used to anchor and protect the steel bar instead of concrete. Typically,
many micro-piles are placed in a grid beneath the structure’s foundation.
The tremendous surface area of the micro-pile grid provides exceptional frictional
adherence to the native soil, and is the source of this system’s strength.

CFA piles are
constructed by utilizing specialized drilling equipment
and methods developed, in part, by D.J.
Scheffler, Inc. The CFA pile is constructed
by drilling a hollow-stem auger into
the ground. The auger is drilled
to the pile’s desired depth
in a single operation. Thus, very
little soil is displaced. Once at
depth, concrete is pumped through
the auger’s stem, and then
fills the hole as the auger is extracted.
After the concrete is placed, the
steel reinforcement (either an I-beam
or a re-bar cage) is placed into
the still-wet concrete column. Advanced
computer instrumentation monitors
all aspects of pile placement, including:
depth, speed of auger rotation and
rate of advancement, torque, concrete
head pressure, and volume of concrete
placed. CFA piles can be constructed
in diameters ranging from 16 ” to
48”, and up to 120 feet deep.
