Construction Materials Testing (CMT) was founded in 2001 and has since become the premier testing laboratory for many companies in central Iowa.  CMT specializes in geotechnical, Portland cement concrete (PCC), Hot Mix Asphalt (HMA), aggregates, soil, and smoothness (profilometer) testing, in addition to conducting steel and special inspections.   CMT is based in Des Moines, Iowa and is an AASHTO and U.S. Army Corp. of Engineers accredited laboratory.  Each of our technicians carries Iowa Department of Transportation certifications and American Concrete Institute certifications.  We also staff two full time Professional Engineers who are licensed in the state of Iowa.

We have worked on a variety of structural projects over the years that include the Birdland Levee Reconstruction (2011-2012), Adair County Wind Farm (2008-2009) Story County Wind Farm in Iowa (2008-2009), South East Polk High School (2008-2009) in Des Moines, the Iowa Speedway (2006) in Newton, Jack Trice Stadium (2003) in Ames, and the Iowa Laboratories Facility (2002-2003) in Ankeny.

Our paving projects include Highway 20, Highway 30, I-35, I-235, I-80 and a variety of county road projects.  CMT is the only independent accredited laboratory in Iowa conducting smoothness (profilometer) testing.  We have also assisted at several regional airports, such as at the Ames Airport, Ankeny Airport, as well as larger airports such as the Waterloo Airport and Des Moines International Airport, all in Iowa.   

CMT performs quality control and testing services for some of the largest construction companies, design firms and government agencies in the state of Iowa, such as the City of Ames, the National Guard Training Facility at Camp Dodge, Neumann Brothers, Martin Marietta Aggregates, Manatt’s Corporation, Cedar Valley Corporation, Grimes Asphalt & Paving, and Harold Pike Construction.  We work on a daily basis with firms such as Bolton & Menk Engineers & Surveyors, Dallas County Environmental Health, Fox Engineering, Snyder & Associates, Tometich Engineering and WHKS.
