LABORATORY TESTING

The Soils & Structures laboratory testing facilities offer in house services for a wide range of geotechnical and construction materials that provide you with prompt service and accurate results to create solutions for your project goals.

As an AASHTO accredited laboratory, we participate in a number of inter-laboratory studies and certification to ensure the quality of our results. Our skilled team of technicians, has extensive experience in our newly updated laboratory with the most current testing equipment. We have abilities, that many larger firms do not have including, quick turnaround, daily coordination with field technicians, drillers and engineers to complete and provide you with the data necessary to keep your project on time.
