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.

Steel casings (Figure 6-10) are used to support drilled holes when unstable conditions are
encountered. Various methods have been used to advance steel casings, among them,
spinning the casing with the Kelly Bar while applying some vertical force, driving the
casing with whatever means are available as the hole is drilled, or using a vibratory
hammer. Steel casings are generally extracted from the hole in the manner specified in the
contract specifications as concrete is placed.
Drilling Methods
Various other materials are used to supplement the drilling work. Water is sometimes added
to certain ground formations to assist drilling and lifting materials from the hole. Soil may
be placed back into the hole to dry out supersaturated materials. The drilling tool is used to
agitate the materials so they can be extracted from the hole. This is known as “processing”
the hole.
