Chemical Grouting

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.

Figure 7-11: Double Acting Steam/Air Hammer
Differential Acting Steam/Air Hammer
The differential acting steam/air hammer is similar to a double acting hammer. Com-
pressed air or steam (motive fluid) is introduced between large and small piston heads to
lift the ram to the top of its stroke. Motive fluid is then introduced over the large piston head
to accelerate the ram in its down stroke. Refer to Figure 7-12.
The rated striking energy delivered per blow by a differential acting steam/air hammer is
calculated by adding the differential force due to the motive fluid pressure acting over the
