Hollow Stem Auger Services

Hollow-Stem Auger Drilling

Pitcher Services specializes in rotary drilling but many of our rigs are capable of deploying augers in the initial portion of a borehole before switching to rotary methods. This can be beneficial when conducting groundwater sampling in shallower stratigraphy and we would typically deploy hollow stem auger methods when drilling to relatively shallow depths and installing smaller monitoring wells.

Pitcher’s drillers and operators are reliable and efficient whether working on a geotechnical sampling project or collecting samples for environmental analysis.


Variable Equipment:

Pitcher operates both truck and track mounted rigs for both geotechnical and environmental site investigations. Truck mounted drills are perfect for metro areas whereas tracked equipment is useful for difficult access and off-road locations. Our combination auger/rotary drills are equipped with automatic SPT hammers for geotechnical sampling and can utilize other systems to complete continuous sampling, coring and environmental sampling.
