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

Slurry Displacement Piles
9-10
CALTRANS FOUNDATION MANUAL
within the parameters described in the contract specifications should have negligible
settlement of suspended materials during concrete placement provided the rebar cage and
concrete are placed promptly.
The contract specifications set parameters for some of the physical properties of drilling
slurries. The four specified physical properties are density, sand content, pH, and viscosity.
These are described in the following paragraphs.
Density
Density, or unit weight, is a function of the amount of solids held in suspension by the
drilling slurry. Since mineral slurries will hold solids in suspension for long periods, the
allowable density value is higher than that permitted for polymer slurries and water, which
do not hold solids in suspension as well. The density of the drilling slurry may be affected by
its viscosity since a more viscous fluid will suspend more solids. The reason for having an
upper limit on the allowable density value is that drilling slurries with higher densities are
unstable with respect to their ability to suspend solids. These solids could settle out during
concrete placement and cause pile defects.
