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. Please

Foundation Investigations

CALTRANS FOUNDATION MANUAL
Sand, being non-plastic, will not form a plastic thread by rolling it on a smooth surface.
Silt will form a thread when rolled, but it is weak and crumbles as it dries. Clay forms a
plastic thread of high strength, which dries slowly and usually becomes stiff and tough as it
dries.
Sand has no unconfined dry strength. Silt has very little dry strength and easily powders
when rubbed. Clay has a high dry strength and will not powder easily.
A rough indication of the permeability of a soil is shown by its reaction to shaking or
patting. When a small amount of silt is subjected to this type of movement, water appears
on the surface, which assumes a "livery" appearance. Upon shaking or patting clay, this
reaction occurs slowly or not at all.
Geotechnical Drilling and
Sampling Equipment
Many different pieces of equipment are used by foundation drilling crews and engineering
geologists to obtain samples and evaluate subsurface conditions.
It is important for Structure Construction employees to have a good working knowledge of
the equipment used during the subsurface drilling operation for their projects. The different
pieces of equipment used to perform the drilling operation have different levels of reliability.
The reliability of the equipment used during the subsurface investigation is an important
factor for the Structure Representative to take into consideration during the early phases of
a project.
The following is a brief description of the various pieces of equipment used by the Office of
Structural Foundations as well as consultant geotechnical companies.
