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.

General
A cofferdam is a retaining structure, usually temporary in nature, which is used to support
the sides of deep excavations where water is present. These structures generally consist of:
(1) vertical sheet piling, (2) a bracing system composed of either wales and struts or
prestressed tiebacks, and (3) a bottom seal course if required to seal out water.
Cofferdams are used in situations where adjacent ground must be supported against
settlement or slides, and in construction of bridge piers and abutments in relatively shallow
water.
Contractor’s Responsibility
Cofferdams usually fall under the category of temporary features necessary to construct the
work. As such, the Contractor is responsible for the proper design, construction, mainte-
nance and removal of cofferdams. The Contractor is required to submit working drawings
to the Engineer for approval in accordance with Sections 5-1.02 and 19-3.03 of the Stan-
dard Specifications. The Contractor is also required to comply with the applicable sections
of the Construction Safety Orders (Section 1811) and the provisions of Section 6705 of the
Labor Code.
