Laboratory Services: Accredited Soil and Rock Testing

Top-notch geotechnical engineering requires equally capable in-house soil testing facilities. In support of our geotechnical design and construction monitoring services, GeoStructures maintains an AASHTO and Army Corps of Engineers-accredited laboratory for soil and rock testing. Keeping true to our commitment to excellence, we have invested in state-of-the-art, computer-controlled, servo hydraulic triaxial and constant rate of strain (CRS) consolidation testing equipment. With the advent of CRS consolidation, we offer more accurate results than incremental consolidation as well as a reduced turnaround time of only 2 to 3 days—a dramatic reduction from the 2 weeks required for standard testing!

Specialized stress path triaxial testing makes it possible for us to consolidate soil specimens before shearing at conditions that model in-situ stresses, thereby improving the usefulness of such endeavors. At the present time, there are only a handful of engineering firms nationwide with such capabilities. Fully trained staff engineers perform all of our testing.
