Chemical Grouting
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
JULY
1997
9-11
Density is tested using the test kit shown in Figure 9-5 in conformance with the test method
described in American Petroleum Institute (API) Recommended Practice 13B-1, Section 1.
This test method is included in Appendix G.
Sand Content
Sand content is an important parameter to keep under control, particularly just prior to
concrete placement. Sand is defined as any material that will not pass through a No. 200
sieve. Since mineral slurries will hold sand particles and other solids in suspension, the
allowable sand content value is higher than that permitted for polymer slurries and water,
which do not hold these solids in suspension as well. The primary reason for setting an
upper limit on the sand content value is to prevent significant amounts of sand from falling
out of suspension during concrete placement. A secondary reason for setting an upper limit
on the sand content value is that high sand content can increase the amount of filter cake
on the sides of the drilled hole in mineral slurries. This increased filter cake might have to
be physically removed before concrete could be placed in the drilled hole. Allowing the filter
cake to remain would decrease the skin friction value of the pile, which is not desirable.
