Fugro Nigeria Limited is
the African
leader in the
development and
application of Cone
Penetration Testing
(CPT) technology. It
has a
variety of penetrometers,
probes and samplers
that are
hydraulically pushed
into the soil to
obtain physical and
chemical properties
of soil. The speed
and quality of CPT
data surpasses
conventional
drilling and
sampling methods and
eliminates much of
the subjectivity of
conventional logging
techniques. Fugro Nigeria Limited offers lightweight
detachable CPT units
for difficult access
sites as well as
large trucks and
all-terrain
vehicles, which
eliminate the need
for ground anchors
to provide
penetration
reaction.
In-situ Cone
Fugro Nigeria Limited 's
in-situ probes can
be fitted with
sensors and/or
sample collection
devices to
continuously measure
subsurface soil or
groundwater
characteristics.
These features allow
the professional to
immediately detect
subtle changes in
geological,
geotechnical or
hydro geological
conditions. We use
the data
with
specialized software
to produce contour
maps in three
dimensional
projections. These
visual portrayals of
surface stratigraphy
or groundwater
conditions are our
effective way to
illustrate in-situ
conditions.
Seismic Cone
Fugro Nigeria Limited 's
seismic cone test
method is a
reliable, cost
efficient technique
to determine in-situ
seismic wave
velocities. The
method allows us to
measure the travel
times of body waves
propagating between
a wave source on the
ground surface and
an array of
geophones in an
in-situ seismic cone penetrometer. These
body waves comprise
shear waves
(S-waves) and
compressional or
primary pressure
waves (P-waves). The
seismic wave
velocities give us an
indication of ground
characteristics
relevant for
assessing the
response of
dynamically loaded
foundations and for
earthquake related
studies.
Pressure Cone
Fugro Nigeria Limited 's Cone
Pressuremeter
combines the
advantage of
detailed CPT soil
profiling with
determination of
local soil
stress-strain
properties through a
pressuremeter
mounted behind a
cone penetrometer.
Numerous
international
research projects
and commercial
applications have
proven that key
geotechnical design
parameters can thus
be obtained reliably
and cost
effectively.
