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

In granular soils, it is important that the fine particles not be carried away by pumping.
Loss of fines may impair the bearing capacity and cause settlement of existing structures.
The amount of soil particles carried away can be determined by periodically collecting
discharge water in a container and observing the amount of sediment.
If there is a large flow of groundwater and prolonged pumping is required, the sump(s)
should be lined with a filter material to prevent or minimize loss of fines.
When it becomes necessary to lower the water table, one commonly used method is the
single well point system (Figure 4-14).
A well point is a section of perforated pipe 2 to 3 inches in diameter and 2 to 4 feet in
length. The perforations are covered with a screen and the end of the pipe is equipped with
a driving head and/or holes for jetting. Well points are connected to 2 to 3 inch diameter
riser pipes and are inserted into the ground by driving and/or jetting. The riser pipes, which
are spaced at 2 to 5 foot centers, are connected to a header pipe which is connected to a
pump.
Figure 4-14: Single Stage Well Point System
A single stage well point system can lower the water table 15 to 18 feet below the elevation of
the header pipe. For greater depths a multiple stage system must be used.
