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

Cofferdams and Seal Courses
12-2
Engineer’s Responsibility
The Engineer is responsible for checking and approving the Contractor’s drawings, and for
making the decision as to whether a seal course should or should not be used. If the
thickness of the seal course is not shown on the plans, the Engineer must determine the
thickness of seal course concrete needed.
The Engineer should be familiar with the information in the following sections of the
Standard Specifications: 5-1.02, 19-3.03, 19-3.04, 51-1.10, 51-1.22; and the following
Bridge Construction Memos: 2-9.0 and 130-4.0.
Sheet Piles and Bracing
There are three basic materials used for the construction of sheet piles: wood, concrete, and
steel.
Wood sheet piling can consist of a single line of boards or “single-sheet piling” but it is
suitable for only comparatively small excavations where there is no serious ground water
problem.
Figure 12-1: Single Sheet Piling
In saturated soils, particularly in sands and gravels, it is necessary to use a more elaborate
form of sheet piling which can be made reasonably watertight with overlapping boards
spiked or bolted together, such as the “lapped-sheet piling” or “Wakefield” system.
