Our geotechnical department will perform the explorations and evaluations necessary to get your project off the ground.

Our seasoned team of professional engineers, geologists and drillers will start off your project strong by exploring the grounds of your site. Summit’s geotechnical leaders will talk with you to assemble the team most fitting for your needs. We are unique in our ability to reach and assess almost any site in person, and our dedicated teams have diverse experience from performing thousands of evaluations throughout the state.

We own and operate multiple drill rigs and soil testing laboratories strategically placed to have access to any client. Our rigs can handle almost any terrain, so you’ll never have to worry about us being able to go where you need us. Our state-of-the-art labs are AASHTO and CCRL certified and stocked with the latest equipment for precise results.

These qualifications mean we are not limited by the constraints of equipment accessibility, laboratory capability, or assumed geological consistency. For you, our team has practically every means of discovering site inconsistencies and possessing that knowledge early on ensures project cost-savings during design and construction.

Soil is our forte, and we are up to any challenge, no matter what type you’re trying to build on.
