Field and Laboratory Testing

We provide a wide range of competitively priced soil, rock, concrete and asphalt field and laboratory testing services. Each test is performed according to current ASTM, AASHTO, DOT or COE specifications. We are also able to perform tests according to other standards. Tests can be customized to meet specific project needs. A complete schedule of laboratory testing services and fees is available upon request.
