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
1-6
deposits of soil and gravel are difficult to sample and test in the laboratory. To overcome
these difficulties, in-situ test methods must be used to measure soil parameters.
The most common in-situ test used during a subsurface investigation is the Standard
Penetration Test (SPT). The test results in a penetration resistance value, “N”. The “N”
value can be used to estimate the angle of friction of a cohesionless soil, the unconfined
compressive strength of a cohesive soil, and the unit weight of a soil (refer to Appendix A).
Other in-situ tests are the static cone test, pressure meter test, vane shear test, and the
borehole shear test. In-situ tests, such as the vane shear and Iowa borehole shear tests,
provide soil shear strength parameters, such as cohesion, angle of internal friction, and
shear strength.
These design parameters are used for static analytical design procedures for pile founda-
tions and may also provide valuable information to a Structure Representative during the
course of a construction project.
Log of Test Borings
After the subsurface investigation is complete, the Engineering Geologist develops the Log of
Test Borings (Refer to Appendix A for examples). The Log of Test Borings includes a plan
view showing the location of each boring retrieved during the subsurface drilling operation.
It provides a graphic description of the various layers of geological formations, soils, and
the location of the groundwater table (if encountered). Various soil and rock properties are
also described. Each Log of Test Borings includes a standard legend on the left side of the
sheet that describes the different symbols and notations used within the Log of Test Borings
(refer to Appendix A for a standard Log of Test Borings legend).
Foundation Report
Once the Log of Test Borings is complete, the Engineering Geologist performing the
foundation investigation develops the Foundation Report (refer to Appendix A for an
example of a Foundation Report). The foundation report is basically a compilation of all
the information retrieved during the foundation investigation and provides the Project
Designer with a description and an evaluation of the geological formations and soils
present at the site of a proposed project.
