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.

A third reason for pile defects is concrete mix design and placement problems. Whenever
the seal between the head of concrete and the drilling slurry is lost, a defect is very likely to
result. This is because entrapment of drilling slurry within the concrete is almost inevitable
under this circumstance (Figure 9-25). If the concrete placement tube loses its seal and
allows concrete from the placement tube to drop through the drilling slurry onto the head
of concrete, the drilling slurry and any settled material on the head of concrete could be
trapped between the concrete layers, causing a pile defect. If the concrete head begins to set,
the concrete can “fold” over as it is rising through the rebar cage and entrap drilling slurry
and any settled materials as previously described. Another type of pile defect can result due
to concrete mix design problems. The Engineer should not permit the use of excess water in
the concrete mix design or allow additional water to be mixed with the concrete at the
