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.

Tiebacks, Tiedowns, and Soil Nails

Safety
Check the Contractor’s construction sequence against the approved plans. As excavation
proceeds from the top down, look for signs of failure in the lagging or changes in the soil
strata.
Tiedowns
Tiedowns are commonly used in footings on seismic retrofit projects. They are used to
provide additional restraint against rotation of the footings and can be installed in both soil
and rock. Tiedowns and tiebacks are constructed similarly but differ in their angle of
reference. Tiedowns are installed with reference to a vertical zero angle, whereas tiebacks
are referenced to a horizontal zero angle.
An example of a prestressing bar tiedown anchor is shown in Figure 11-2.
