PSI was one of the early developers of direct push technology; direct push innovations included “Dual Tube” continuous coring (Enviro-Core) and the Continuous Multi-Channel Tubing system (CMT) for sampling and monitoring.

In 1999, PSI was acquired by an investor group. As PSI evolved along-side the drilling services and environmental/geotechnical consulting markets, it developed more innovative technologies to meet its original objectives. In 2007, Precision Sampling, Inc. acquired Spectrum Exploration and folded Spectrum’s Stockton, CA, Colorado Springs, CO and Albuquerque, NM operations into the Precision Sampling family. Today, with three locations and a wide array of drilling, grouting and remediation technologies, PSI now provides its clients with a diverse array of tools and techniques to perform geologic field investigation projects quickly and cost effectively.

Precision Sampling does not aspire to be everything to all companies rather we will strive to be more than everything you look for in a project partner.

Our aim is to provide the highest quality geological, geotechnical, grouting and environmental drilling services to our customers.
