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

Slurry Displacement Piles
9-6
The filtration process is dependent upon many variables. These include the nature of the
ground formation, the amount of time the drilling slurry is in the drilled hole, the presence
of contaminants in the ground formation or groundwater, and the chemical additives used
in the drilling slurry, just to name a few. In general, the nature of the ground formation
and the amount of time the drilling slurry is in the drilled hole are the most important
variables.
The nature of the ground formation has an effect on the thickness of the filter cake that
develops on the sides of the drilled hole. In general, thicker cakes will form in looser ground
formations, such as open sands and gravels. Because the pore spaces between the individual
soil grains are larger in looser ground formations, the drilling slurry particles that are
driven into the ground formation by positive effective stress tend to flow past the soil grains
(Figure 9-3(a)). However, the drilling slurry particles will build up against the exposed
faces of the soil grains. This build-up is capable of forming a thick filter cake on the sides of
the drilled hole in a short period of time. In tighter ground formations, such as dense sands
and cohesive soils, the pore spaces between the individual soil grains are much smaller. The
drilling slurry particles tend to fill in the pore spaces (Figure 9-3(b)). Once the pore spaces
are filled, drilling slurry cannot be forced into the ground formation by positive effective
stress. This causes the build-up of filter cake to cease, resulting in a thinner filter cake
build-up than would be observed in looser ground formations.
