Fast, accurate testing on your schedule
When geotechnical and materials test results lag, so do projects. With the largest U.S. network of accredited and validated laboratories among our peers and many specialized testing capabilities, we provide fast, accurate results no matter the size or complexity of your project.
Our laboratory engineers and technicians do more than deliver test data — they identify potential concerns and develop solutions to keep your project moving forward. To further your goals, we leverage our:
Unmatched capacity: We don’t just offer a wide range of tests — we can run them at scale. Our labs are equipped to handle high volumes with fast turnaround times, helping you avoid costly delays.
National footprint, local expertise: Our laboratory professionals are deeply familiar with local, state, and federal specifications for compliance and precision in every test.
Multiple accreditations: We maintain laboratory accreditation certification through the American Association of State Highway and Transportation Officials (AASHTO) Accreditation Program (AAP) and the United States Army Corps of Engineers (USACE), among others.
Client-driven mindset: We continually expand our services based on client needs — regularly adding tests, equipment, and expertise to stay ahead of industry demands. Recent additions include petrographic analysis, large direct shear testing, and evaluation of carbon fiber wrap.
Sustainability focus: When we’ve completed testing, many offices recycle geotechnical soil samples, concrete cylinders, and plastic molds.
