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

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

Footing Foundations
4-14
groundwater is encountered during excavation, dewatering shall be commenced
and shall precede in advance of or concurrent with further excavation. When
unsuitable foundation material is encountered at planned footing elevation, the
corrective work will be as directed by the Engineer. Payment for additional work
will be at contract prices (preferred) and/or extra work, as determined by the
Engineer. When footing concrete or masonry is to rest upon rock, removal shall be
as required to expose sound rock. Bearing surfaces shall be roughly leveled or cut
to steps and roughened. Seams shall be pressure-grouted or treated as directed by
the Engineer and the cost of such work will be paid for as extra work.
Section 51-1.04: Pumping from foundation enclosures shall be done in such a manner as
to preclude removal of any portion of concrete materials. Pumping is not permit-
ted during concrete placement, or for 24 hours thereafter, unless it is done from a
suitable sump separated from the concrete work.
Section 51-1.09: After placing, vibrating, and screeding concrete in footings that have both
a top mat of rebar and are over 2-
1
/
2
feet deep, the top one foot of concrete shall be
reconsolidated as late as the concrete will respond to vibration, but no sooner than
15 minutes after the initial screeding.

concrete, etc..

Excavations
An obvious hazard associated with footing foundations is the open excavation. Worker
safety must be provided for during excavation operations and/or shoring construction. The
Division of Occupational Safety and Health (DOSH) requires that each employee in an
excavation be protected from cave-ins by an adequate protective system. The protective
system can consist of either metal or timber shoring, a shield system, or a sloping and
benching system. When a sloping and/or benching system is substituted for shoring or
other protective systems, and the excavation is less than 20 feet deep, DOSH requirements
can be selected by the Contractor in accordance with the requirements of Section 1541.1(b)
of the Construction Safety Orders. Section 1541.1(b)(1) allows slopes to be constructed
(without first classifying the soil) in accordance with the requirements for a Type C soil
