Direct push technology is well suited
for a variety of civil engineering applications. The
collection of vast quantities of subsurface data allows for
a better project design. The following data collection
techniques are available:
Soil Classification
Continuous soil samples can be collected along the proposed
route at designated locations placed at specific intervals.
The soil samples are collected utilizing Geoprobe Systems’
Macro-Core Soil Sampler system, by advancing a 1.75-inch
diameter by 48-inch long steel sampling barrel equipped with
expendable PVC liners. General soil classification and
groundwater observations are provided. Bedrock Profile
Bedrock Profile
Bedrock studies are performed using a solid
end point attached to the standard 1.25-inch
probe rods. The probe is advanced to a
designated depth or until refusal. If
refusal is encountered, the bore hole is
offset 5 to 10 feet, and the probe rod is
advanced again to confirm that bedrock was
encountered.
Groundwater Elevation
The presence of saturated soil is routinely collected during
continuous soil sampling. Temporary
piezometers/observation wells can be installed in open
boreholes constructed of 1-inch diameter PVC well screen and
riser. The water level can measured at the conclusion
of the day or the project.
Why ATL?
-
Geoprobe capability allows ATL to
reduce the cost for subsurface investigation services.
-
Our staff is experienced in both
environmental and geotechnical applications of Geoprobe
usage.
-
The Geoprobe equipment also
facilitates installation of monitoring wells and some types
of remedial applications
