Soil Laboratory Testing Services For Construction And Engineering Providing a full range of professional soils testing and classification.
For 72 years, Testing Service Corporation has been providing accurate soils lab testing for a variety of applications within the construction industry.
That has gained us a reputation of service and reliability. Countless engineers have trusted our results for many of the Chicago area projects.
Additionally, all tests are completed in adherance to ASTM or AASHTO standards. Below, you'll find a full list of all of our laboratory services.
Whether you need a single soil proctor test done, consolidation testing, atterberg limits, or even soil resitivity testing, we've got you covered!
