Quality Assurance
With evaluating the quality of materials before we mine them, to testing our concrete as it's being delivered, Teichert has constant quality control of our products from start to finish.
Our materials undergo numerous tests - both in our certified laboratory and at job sites - to ensure that the products both meet the customers' needs as well as exceed federal, state, or local agency specification requirements.
Teichert's Quality Assurance (QA) lab is accredited by the American Association of State Highway and Transportation Officials, the California Department of Transportation, the Federal Aviation Administration, and other public entities.
Our QA staff also works closely with our Geology department in testing samples to determine the quality of resources at potential aggregate sites.
