Gregg Drilling & Testing, Inc. has effective, state-of-the-art equipment available to apply direct push technology. When applicable, this method allows for the collection of high-quality samples in less time and at lower cost. Unlike conventional drilling, direct push technology does not generate soil cuttings which, if contaminated, require special handling and costly disposal. Geotechnical and environmental samples can now be obtained in previously inaccessible areas and with minimal site impact thanks to the small limited access rigs.
Gregg operates a range of truck mounted, track mounted, and limited access direct push sampling rigs. Our direct push rigs are capable of handling both single and dual tube sampling. Gregg also owns and operates a number of combination drill/direct push rigs that can be converted from the direct push mode to the hollow stem auger mode when direct push refusal is encountered. This gives clients the opportunity to meet project objectives without having to mobilize a second rig.
