Materials Testing
CME’s materials engineers and technicians are experienced and certified to provide on-site testing and observation.
We pride ourselves in responding quickly – often times in the same day – to testing requests. On-site testing abilities include soils, concrete, asphalt, aggregates, structural masonry, spray fireproofing, structural steel, and high strength bolting. With one of the largest materials testing laboratories in the region, CME provides testing to both public and private clients. In addition, CME has four mobile testing laboratories for soils, concrete, and asphalt that are equipped with water and electricity for use on remote sites. Tests include: Soils
