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.

Slurry Displacement Piles

CALTRANS FOUNDATION MANUAL
within the parameters described in the contract specifications should have negligible
settlement of suspended materials during concrete placement provided the rebar cage and
concrete are placed promptly.
The contract specifications set parameters for some of the physical properties of drilling
slurries. The four specified physical properties are density, sand content, pH, and viscosity.
These are described in the following paragraphs.
Density
Density, or unit weight, is a function of the amount of solids held in suspension by the
drilling slurry. Since mineral slurries will hold solids in suspension for long periods, the
allowable density value is higher than that permitted for polymer slurries and water, which
do not hold solids in suspension as well. The density of the drilling slurry may be affected by
its viscosity since a more viscous fluid will suspend more solids. The reason for having an
upper limit on the allowable density value is that drilling slurries with higher densities are
unstable with respect to their ability to suspend solids. These solids could settle out during
concrete placement and cause pile defects.
