Geotechnical Testing

Our fully-equipped laboratories feature skilled technicians and cutting-edge technology .

  • Construction Inspection Testing
  • Full-service Lab
  • On-site Testing.

Our fully-equipped soils laboratory in Pennsylvania features skilled technicians and cutting-edge technology to yield reliable results – the basis for our engineering design services. Our ability to perform testing in-house and on-site translates into reduced costs and better schedule control for you.

Our Expertise

What We Do
  • Geotechnical Testing
    Our laboratory resources allow us to quickly and accurately determine the material characteristics and parameters upon which successful analyses and designs depend. State of the practice equipment and procedures, together with highly qualified personnel, provide quality results.
  • Specialized Geotechnical Testing Programs
    We design and execute programs to address unusual loading conditions in support of forensic analyses or as part of extending technology into new areas or applications.
  • On-site Construction Testing
    We furnish complete on-site laboratories specifically tailored to your project needs.
What You Can Expect
  • Certified Labs
    Our lab is certified by the American Association of State Highway and Transportation Officials (AASHTO) Accreditation Program and perform American Society for Testing and Materials (ASTM) and/or AASHTO test procedures.
  • Quality Control 
    In the lab or on-site, your project will be staffed by qualified technicians and engineers. We provide documented testing services in accordance with recognized standards.
