Rotary Services

Rotary Drilling: Quality sampling and additional testing or instrumentation

Pitcher Services maintains a large inventory of rotary drilling and coring drill rigs that when partnered with our highly experienced drillers, are able to meet a wide range of environmental drilling and geotechnical drilling site investigation needs.

Our full-time mechanics and preventative maintenance program ensure that all necessary equipment is available and operating at maximum efficiency. This commitment to quality allows us to offer the most responsive and cost effective drilling services.

Depending on your project requirements, Pitcher can advise you on the right drill and team to use. From small limited-access drill rigs that fit inside a building, to large truck-mounted drill rigs capable of achieving depths over 1000ft, Pitcher Services has a full suite of choices. Support trucks accompany our rigs to all sites and provide extra equipment at no extra cost to the client.


Full Suite of Capabilities:

Pitcher operates both truck and track mounted rotary rigs for both geotechnical and environmental site investigations. Truck mounted rotary drills are perfect for metro areas whereas tracked equipment is useful for difficult access and off-road locations. We drill up to 1000ft with mud or air rotary and can collect a full suite of geotechnical samples including SPT, California Modified, Shelby tubes and our patented Pitcher barrel sampler. We also offer continuous soil and rock coring in a variety of core sizes.

Pitcher Services can provide additional geotechnical testing such as vane shear tests, pressuremeter and SPT energy calibration. Depending on your project needs, Pitcher also offers instrumentation installation including piezometers and inclinometers to monitor your site.
