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.

The question that may arise from this limitation is why the contract specifications allow the
use of water as a drilling slurry at all. Retaining the limited use of water as a drilling slurry
allows a Contractor, who attempts to dewater a drilled hole using temporary casing and is
unable to do so for whatever reason, to have the option of using the water in the drilled hole
as a drilling slurry to prevent quick conditions at the bottom of the drilled hole and to be
able to place concrete.
The physical properties of water used as a drilling slurry are not as critical as with other
types of drilling slurries. Water is capable of suspending sand and silt only for short periods,
usually less than 30 minutes. This allows soil cuttings to settle to the bottom of the drilled
hole fairly rapidly. Since the pH of water is not important and water will not typically
become more viscous, the contract specifications set parameters for density and sand
content only. Testing these parameters verifies that most of the suspended material has
settled before final cleaning of the drilled hole and concrete placement.
Water used as a drilling slurry can be easily disposed of on site after settlement of all
suspended materials has occurred unless the water has been contaminated by hazardous
materials.
Mineral
Mineral slurries are processed from several different types of clay formations. Although
there are a number of different types of clay formations available, the most commonly used
consist of Bentonite and Attapulgite clay formations.
Bentonite is a rock composed of clay minerals, named after Fort Benton, Wyoming, where
this particular type of rock was first found. It is processed from the clay mineral Sodium
Montmorillonite, which hydrates in water and provides suspension of sands and other
solids.
Bentonite slurry is a mixture of powdered bentonite and water. Bentonite slurry will floccu-
late (destabilize) in the presence of acids and ionized salts and is not recommended for
ground formations where salt water is present without the use of chemical additives.
