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,
caisson,
shoring,
underpinning,
agriculture, and
roads
construction. We
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
compaction grouting,
mini piles,
sinkhole repair,
micropiles,
acrylamide grouting, and
soil nailing.
We will continue to
dedicate ourselves to
excellence,
including
insurance mortgage, in our performance, in our
integrity, and in our relationships with our
customers. We will carefully weigh our
decisions, actions, and results to make sure
that we remain the most trusted name in the
geotechnical contracting industry. Please

to be received by the receiver probe, as opposed to the shorter amount of time it takes for the
sonic wave to be received across a solid medium (sound concrete). A third method would be
to core the pile and recover the physical cores for inspection. This method may be the most
conclusive, but is very time consuming. A fourth method uses a radiographic technique
called gamma ray scattering (Figure 9-21).
Figure 9-21: Gamma Ray Scattering Test Schematic
As of 1994, the contract specifications state that the gamma ray scattering method of testing
piles constructed using the slurry displacement method will be used to determine accep-
tance of the pile. Other methods may be used in the future as the Office of Structural
Foundations develops equipment and expertise.
In gamma ray testing, scatter counts are taken and compared to counts taken on a stan-
dard containing the same material being tested. By this means, relative densities can be
ascertained. In general, the lower the count, the more dense the material. The nuclear
probe used in these tests contains a source which is relatively weak - a plus, considering the
precautions that would otherwise have to be taken - and its effective range of sensitivity is
