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.

Cast-In-Drilled-Hole
Piles
Description
Few terms are as self-descriptive as the one given the Cast-In-Drilled-Hole (CIDH) pile. They
are simply reinforced concrete piles cast in holes drilled to predetermined elevations. Much
experience has been gained with this pile type because of their extensive use in the con-
struction of bridge structures. While they probably are the most economical of all com-
monly used piles, their use is generally limited to certain ground conditions.
The ground formation in which the holes for CIDH piles are to be drilled must be of such a
nature that the drilled holes will retain their shape and will not cave in when concrete is
placed. Because of cave-in and concrete placement difficulties, these piles are not recom-
mended for use as battered piles. Nor are they recommended where groundwater is present,
unless dewatering can be done without unreasonable effort and unless concrete can be
placed without a casing having to remain in place. If groundwater or caving conditions are
present, the piles can be constructed by the slurry displacement method if permitted in the
contract specifications. The slurry displacement method is described in detail in Chapter 9
of this manual.
