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

Regardless of the worker protection system used, the Contractor’s Shoring Plan or Excava-
tion Safety Plan should be inspected to ensure compliance with DOSH requirements.
Daily inspections (or after any hazard-increasing occurrence) of excavations or protective
systems shall be made by the Contractor’s “competent person” for evidence of any condition
that could result in cave-ins, failure of a protective system, hazardous atmospheres, or any
other hazardous condition. When any evidence of a situation is found that could result in a
hazardous condition, exposed employees shall be removed until the necessary precautions
have been taken to ensure their safety.
Safety railing must be located at the excavation perimeter, preferably attached to the
shoring that extends above the surrounding ground surface. If the shoring does not extend
above the ground, then the railing must be located a sufficient distance back from the
excavation lip to adequately protect workmen in the excavation from being injured by
falling objects or debris. Locating the safety rail back away from the excavation lip usually
provides more stable ground to anchor the rail posts. Spoil piles must be located more than
2 feet away from the excavation lip for excavations deeper than 5 feet.
Although the vertical side of a non-shored excavation must be less than 5 feet in height,
care must be exercised when working around the perimeter to avoid falling into the
excavation because of sloughing or slip-out of the material at the excavation lip. Spoil piles
must be located at least one foot away from the excavation lip for trenches less than 5 feet
in depth.
Whenever work is proceeding adjacent to or above the level of vertical projections of exposed
rebar, workers shall be protected against the hazards of impalement on the exposed ends of
the rebar. The impalement hazard can be eliminated by either bending over the ends of the
projecting rebar, or by use of one of the following methods:
1) When work is proceeding at the same level as the exposed protruding rebar, worker
protection can be provided by guarding the exposed ends of rebar with DOSH-approved
protective covers, troughs, or caps. Approved manufactured covers, troughs, or caps
will have the manufacturer’s name, model number, and the Cal/OSHA approval
number embossed or stenciled on the cover, trough, or cap. Any manufactured protec-
tive device not so identified is illegal.
2) When work is proceeding above any surface of protruding rebar, impalement protec-
tion shall be provided by the use of: (1) guardrails, (2) an approved fall protection
system, or (3) approved protective covers or troughs. Caps are prohibited for use as
impalement protection for workers working above the level of the protruding rebar.
