State-of-the-Art Chemical Testing Laboratory

Arrow

AET has invested in a state-of-the-art chemistry lab in Saint Paul to serve our clients nationwide. Our senior chemists have a over 60 years of combined experience with the chemical analysis of concrete and construction materials in independent, production, and manufacturing environments. We provide a full suite of chemical, analytical and spectroscopic services and tests for the construction industry.

In collaboration with our Petrography Group, Asphalt Lab and Cement/Concrete Lab, our chemical testing laboratory supports engineers, architects, building owners, manufacturers, government agencies, product developers and state departments of transportation as well as other chemists and petrographers.

AET's Chemistry services add value to client projects by not only providing routine chemical testing and analysis, but also by helping clients determine how testing can be designed and utilized to best serve their particular needs. Forensic testing helps identify the source of the problem and what happened, so our clients can reduce re-occurrences. They also learn how to improve their products or uses of their materials. Our chemical analyses and services include, but are not limited to investigations of:

• Adhesives
• Caulks and Sealants
• Chemical admixture and additives
• Concrete curing compounds and sealers
• Paints and Coatings
• Polymers
• Portland cement and products:
   - concrete
   - mortar (modern and historic)
   - stucco/plaster
• Sheet and vinyl composition flooring
