About CMT

Helping Your Team Build Better

Doug Clement founded Construction Materials Testing in 2001. Since then, the company has become the premier testing laboratory in the state. CMT performs quality control testing, research, and engineering services for a wide variety of contractors, manufacturers, engineering firms, city, county, state, and national organizations. Our experience and expertise with Portland Cement Concrete (PCC), Hot Mix Asphalt (HMA), aggregates, soils, and smoothness testing (profilometer) allow us to assist any project from design to completion.

In 2003 steel testing was added to our services in order to make CMT a true “one stop shop”. In 2005 CMT performed testing on its first project in the Cayman Islands. Since then CMT has conducted testing and engineering services in 12 states, 4 countries and multiple sites in the Caribbean. In 2021 CMT completed a remodel of our lab and office space doubling our square footage so as to better serve our ever growing clientele.

In 22 years our staff has grown from the original 5 technicians to more than 20 highly trained engineering technicians. Our laboratory is accredited by AASHTO ReSource, CCRL and the Army Corps of Engineers. Our technicians carry a vast array of certifications from the Iowa DOT, ACI, NICET, and various other state DOT’s where we have been asked to conduct testing.

CMT strives to complete each project on time and under budget. We assist the clients with economical decision making, timely responses to continue with the project and accurate documentation for as-builts. CMT values relationships and recognizes that all businesses are built from the ground up, with solid relationships and workmanship. Choose CMT to be a part of your construction team!
