Laboratory Testing

Laboratory Testing | Soils & Structures

The Soils & Structures laboratory testing facility offers a wide range of geotechnical and construction materials testing services with prompt service and accurate results.

Our lab is dedicated to supporting our clients and engineering department by providing the numbers needed to assure the quality of the materials you use and to create solutions you can depend on.
We are an AASHTO accredited laboratory and we participate in a number of inter-laboratory studies and certifications to ensure the quality of our results, both as a laboratory and as individual testers. Last year we constructed a newly outfitted lab building purposed solely to maintaining the various controlled environments needed to perform testing with both safety and precision.
