Pioneer2 Drilling Rig



The multi-purpose Pioneer drilling rig was developed by Geotechnical Engineering to be a versatile and powerful machine to carry out a wide variety of ground investigations in many different locations. It is a compact self-contained track mounted dynamic sampling and coring system, designed to retrieve high quality soil and rock samples for geotechnical and geo-environmental investigations.  


The rig is mobilised to site safely and securely on a tachographed flat-bed vehicle owned and managed by Geotechnical Engineering Ltd.  The ancillary kit and materials are transported within the support vehicle and the operation is supported by an experienced and trained two man crew, often accompanied by one of our engineering geologists.


For safety the rig is operated by a diesel engine and fitted with both a Chalwyn valve and spark arrestor


For areas of hardstanding we can provide surface coring ability in both concrete and tarmacadam prior to carrying out service clearance in accordance with HSG47.


Boreholes can be formed in restricted access areas, and can be formed and sampled at any angle.


Soft soils are investigated using dynamic sampling up to 20m deep to obtain continuous samples of up to 112 diameter retained in a semi-rigid plastic liner providing a continuous soil profile for ground modelling and sampling.  Discrete strata can be identified for contamination sampling purposes.  Rotary core drilling up to 112mm diameter can be carried out up to 50m deep to obtain continuous rock cores of up to 112mm diameter, again retained in a semi-rigid plastic liner.


In-situ testing in the form of calibrated SPTs in general accordance with BS EN ISO 22476-3 can be carried out.  Undisturbed UT100, U100 and U70 samples can be taken in cohesive soils.


Borehole instrumentation can be installed including 19mm and 50mm standpipes and pneumatic, hydraulic or vibrating wire piezometers for groundwater or gas monitoring and inclinometer tubing to monitor slope movement.


Geotechnical Engineering’s Pioneer rigs have been used extensively throughout many UK sectors.  Our extensive fleet provides support to many the rail and road projects including electrification and managed motorways.  The utility sector depends on our reliability in providing an accredited service with calibrated equipment and trained staff.


Whether your requirement is for a domestic subsidence project or a multi-million construction project we have the experience and capacity to provide your Client with quality data.
