Construction Materials Testing & Lab Services

Our nationally accredited onsite laboratory in Denver, CO has the capability for standard and specialized testing of aggregates, admixtures, concrete, cementitious materials, grout, dimensional stone, cast stone, and masonry. Our team of laboratory staff are experienced with testing a full range of construction materials relating to various concrete mix designs to meet the requirements for strength, appearance, durability, economy, etc.

As well as soils testing in the Denver area, we frequently perform materials quality assurance and quality control to ensure that any materials being used on the construction site are in line with project plans and specifications.
