American Engineering Testing Inc. (AET) is an employee-owned corporation providing geotechnical, environmental, materials and forensics consulting and testing services to public and private sector clients in a broad spectrum of industries.

We have built our reputation on experience, quality, and fulfilling client requirements. Many of our engineers and certified technicians, including principals who are actively involved in project management, have decades of practical experience in their areas of specialization. They also have access to an extraordinary accumulation of site data and construction history in the Upper Midwest, which proves useful as well as cost- and time-efficient on many projects.

As a consulting engineering company and independent laboratory, quality is the nature and purpose of all our services. We test, analyze, monitor and inspect in order to document, verify and sometimes improve the design and construction effort. To that end, we are accredited by the AASHTO Materials Reference Laboratory (AMRL) to perform geotechnical and construction services in accordance with ASTM: E329. Our own in-house quality assurance/quality control program was established in 1993 to systematically and rigorously audit all departments and office/labs on test procedures, calibrations and test accuracies.
