Our
techniques apply when adding new structures:
especially
rock anchor,
microfine cement,
soil nailing,
micropile
installations for
foundation support.
We
specialize in
slope stabilization,
anchors,
permeation grouting,
foundation repair
and support,
grouting,
soil nails,
rock drilling,
micropile installations, and
sinkholes. We
use a
problem-solving approach geotechnical
architecture of buildings, bridges,
water plants, sewage plants, tunnels,
sinkholes,

are experienced in these applications:
micro piles,
sinkhole repair,
permeation grouting, pressure
grout,
soil nails,
chemical grouting,
micropiles,
compaction grout, and
rock anchors.
Our specialties are
rock anchor,
acrylamide and

Slurry Displacement Piles
JULY

Figure 9-20: Location of Inspection Tubes within the Pile
The Contractor has the responsibility for placement of the inspection tubes. After concrete
placement and before testing, the tubes shall be checked for blockages and straightness with
a dummy probe which is the same size and shape as the test probe. Tubes that cannot
accept the dummy probe shall be replaced with a 2 inch diameter cored hole the full length
of the pile.
Determining the soundness of slurry displacement piles is of understandable concern. There
are a number of methods that may be used to test the soundness of these piles. One method
is the use of external vibration, which measures stress wave propagations in the pile using
either internal or external receivers. This requires a variety of expensive electronic gear and
skilled operators, as well as the placement of instrumentation on the pile rebar cage prior to
concrete placement. Another method uses an acoustical technique, which is commonly
referred to as cross-hole sonic logging. This involves lowering sender and receiver probes
into the inspection tubes to measure the velocity of sonic waves through the concrete.
Defective concrete is registered by the increased amount of time it takes for the sonic wave
