Geotechnical Investigation Services

Whether it’s a multistory office building, a new residential development, an industrial facility, a highway, a dam, or a sewer system, our clients need to know everything about the project site, the construction materials, and how both might affect their project and its end users.

We offer a wide variety of investigative services, including deep or shallow foundations, slope stability analysis, lagoon and landfill investigations, elevated and at-grade water tower and tank structures, dam structures, and other earth retention structures. Our experienced staff members can provide complete quality control testing services for earthwork, concrete construction, and footing inspections. We also offer in-house and field laboratory testing, as well as environmental testing.
