GEOTECHNICAL DRILLING
GEOTECHNICAL SERVICES:
Great West Drilling rigs are completely equipped for drilling in the most difficult rock and soil conditions. Drive samples are obtained safely and efficiently through the use of automatic drop hammers.
The AP1000 Becker Hammer equipment is supercharged for increased driving energy and more efficient operation.
Our equipment is in compliance with the engineering specifications for determining penetration resistance using the Becker Hammer to drive closed drill pipe as a large diameter penetrometer.
GWD personnel have extensive experience with geotechnical sampling methods and installation of instrumentation including piezometers, inclinometers, bench markers, settlement monuments, and others.

EXPLORATION DRILLING
APPLICATIONS:
Great West Drilling's Becker Hammer, Dual Wall Air Percussion, Rotary, and Hollow Stem Auger equipment is ideal for sampling formations and groundwater, and for well construction through the inside of the drill string. The unique, enclosed circulation system used by the Becker Hammer and Dual Wall Air Rotary drill completely contains samples of material and groundwater to avoid cross contamination.
Water bearing zones can be accurately delineated with these drills since no drilling fluids, other than air, are used. Open face bits allow for undisturbed sampling ahead of the bit with split spoons, tube samplers, groundwater samplers, core barrels and other sampling devices.
We provide OSHA 40 hour health and safety training, supervisor training and annual 8 hour refresher courses for our employees.
