Gregg Drilling, LLC (Gregg) has been conducting geotechnical and environmental site investigations for over 35 years. We have always strived to leave as little impact at a site as possible and make it a requirement to always restore a site to its original condition prior to terminating drilling operations.

We are one of the largest site investigation providers in the Western US offering a full suite of drilling, cone penetration testing, sampling, remediation and well services. In addition, our experienced personnel can maintain a high productivity rate saving time and money to the overall project.

If something isn’t listed here, it doesn’t always mean we don’t know how to help you. Please reach out to one of our project managers, many have operated the equipment themselves and can help craft a site investigation plan that will utilize the best equipment for the job.
