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.

Polymer slurries must be thoroughly mixed but do not require additional time to hydrate.
This is because polymer slurries do not hydrate in water. Water used to mix with the
emulsion PHPA polymer must have a pH in the range of 9 to 11 in order to properly disperse
the polymer. A more acidic pH will cause the polymer slurry to flocculate and become
ineffective. A mixing tank is usually required in order to regulate the water. The manufac-
turer of Super Mud recommends tank mixing, but mixing directly into the drilled hole by
introducing the Super Mud fluid into the flow of water is also acceptable to the manufac-
turer. Dry vinyl polymer in granular form is not as sensitive to the pH of water and will
disperse in a more acidic environment and therefore can be mixed directly in the drilled
hole. The manufacturer of SlurryPro CDP™ also recommends tank mixing, but mixing
directly into the drilled hole by sprinkling the dry granules into the flow of water entering
the drilled hole is also acceptable to the manufacturer.
The physical properties of polymer slurries should be carefully monitored during drilling of
the hole and before concrete placement. Because polymer slurries in general do not suspend
particles, the permissible density and sand content values are much lower than those
