TREC has a fleet of five Geoprobes to meet your site investigation needs. All rigs have been completely refurbished in the last 3 years as part of TREC’s Sustainability Program. A team of many experienced operators ensures we are readily available to provide timely response to any site investigation project. As part of our services and to allow for seamless contracting by using one contractor, TREC also provides Ground Penetrating Radar (GPR) and Utility Locating Services. TREC has recently implemented industry specific PFAs sample collection training and SOPs into our site investigation work.

Geoprobe Fleet

Geoprobe™ Model 54 LT

As part of our Geoprobe™ services, we also offer air knifing utility location. Using compressed air and our state of the art Utilivac we are able to locate and clear site utility prior to drilling or excavation work.

Geoprobe™ Model 6620 DT

This larger track mounted Geoprobe allows access in the roughest terrains. Its larger size allows us to drive larger probes and achieve greater depths. This rig also turns 4.25 inch hollow stem augers allowing for the installation of 2″ monitoring wells.

Geoprobe™ 77 Series

Designed to adapt to your changing work roles, the size to power ratio suits environmental work in tight urban cores or geotechnical work in tough remote terrain. Intuitive controls, reduced interaction with the tooling, and redundancy on safety controls as compared to conventional rotary drilling rigs builds the confidence of the next generation of drillers.

Geoprobe™ Model E-540 UD

The E-540 has a 22 horsepower engine and is otherwise a traditional Geoprobe rig for sites that have good access.

Geoprobe™ Model 420 M

The 420M is a portable drill rig easily maneuvered through narrow doorways and into basements. Weighing less than 425lbs and only 23″ wide by 62″ tall when folded, the 420M can be manually lifted and carried into hard-to-reach job sites.
