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.

Foundation Investigations
July 1997
1-9
The Office of Structural Foundations has adopted a classification system based on the
Unified Soil Classification System. All Foundation Reports and Log of Test Borings now
follow this classification system.
The following is a list of soil definitions used by the Office of Structural Foundations:
CLASSIFICATION
DEFINITION
Boulders Particles of rock that will not pass a 12-inch square opening.
Cobbles Particles of rock that will pass a 12-inch square opening but will be
retained on a 3-inch sieve.
Gravel Particles of rock that will pass a 3-inch sieve but will be retained on a No. 4
sieve.
Sand
Particles of rock that will pass a No. 4 sieve but will be retained on a No. 200
sieve.
Silt
Soil passing a No. 200 sieve that is nonplastic or very slightly plastic and
exhibits little or no strength when air dried.
Clay
Soil passing a No. 200 sieve that can be made to exhibit plasticity (putty-
like properties) within a range of water contents, and that exhibits
considerable strength when air dried.
Organic Soil A soil with sufficient organic content to influence the soil properties.
Peat
A soil composed primarily of vegetable matter in various stages of
decompostion. This soil usually has an organic odor, is dark brown to black
in color, has a spongy consistency, and a texture ranging from fibrous to
amorphous.
Engineering Geologists often describe soils with a series of descriptive adjectives before the
noun. An example of this would be:
“Slightly compact, dark gray, micaceous Clayey Sand.”
This statement describes a material that is predominantly made up of sand, but has enough
clay within it to make it a little plastic when handled.
Visual inspection is generally sufficient to differentiate between the coarse grained soils.
However, the distinctions between soil particles such as silts and clays can be difficult.
Several simple field tests utilizing measures of settling, plasticity, dry strength, and perme-
ability characteristics of the soil permit a more accurate classification of these soils.
Once a soil is immersed in water, sand grains settle rapidly, usually in less than one minute.
Silt settles more slowly, usually from 10 to 60 minutes. Clay will remain in suspension for
several hours.
