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
9-18
While mineral slurries are present in the drilled hole, they must be agitated in order to
maintain their physical properties and to reduce the amount of filter cake buildup on the
sides of the drilled hole. In order to accomplish this, the contract specifications require
mineral slurries to be agitated by either of two methods: (1) the mineral slurry is to be
continuously agitated within the drilled hole, or (2) the mineral slurry is to be recirculated
and cleaned. Either of these methods will provide the necessary continuous agitation of the
mineral slurry. The method that is chosen will depend on the cleanliness of the mineral
slurry in the drilled hole. This is typically influenced by the ground conditions encountered.
Recirculation and cleaning of mineral slurries is accomplished by removing the mineral
slurry from the drilled hole, running it through specialized cleaning equipment, and then
placing the cleaned mineral slurry back in the drilled hole. To meet all of the specification
requirements, a slurry “plant”, which is approximately the size of a railroad boxcar, must
be located adjacent to the work area (Figure 9-9). The slurry plant contains screens,
shakers, desanding centrifuges (Figure 9-10), and agitators, and is capable of mixing,
storing, and cleaning the mineral slurry. Figure 9-11 shows a typical recirculation and
cleaning process. It is very important to remove the mineral slurry from the bottom of the
drilled hole. This is because excessive amounts of suspended materials will eventually settle
to the bottom of the drilled hole. These materials must be removed in order to fully clean
the mineral slurry. Typically, it will take several hours to completely clean the mineral
slurry of sand and other suspended materials.
