CTLGroup's Laboratory Services

Our laboratory staff is accredited and capable of conducting some of the latest test methods including all tests related to self-consolidating concrete (SCC) and ultra-high-performance concrete (UHPC), in addition to the conventional commercial services. CTLGroup’s concrete laboratory testing capabilities run a gamut from the earliest age fresh property tests and continue through long term deformation and durability testing. Our equipment, facilities, and processes are accredited to conduct ASTM, AASHTO, CSA, USACE, and EN test procedures on a routine basis, and have the flexibility to perform many tests outside our standard services when called upon.

CTLGroup’s laboratory services can provide laboratory stock materials for projects in which one mixture component is being evaluated,  but can also accommodate large quantities of client-supplied materials when all aspects of a mixture are being assessed. Our controlled laboratory environments can simulate extreme temperature environments in addition to standard conditions for projects where the impact of climatic forces is important. Our high regulated drying labs and moist curing facilities give us and our clients a high level of confidence in the results of tests conducted in those spaces and reduce/eliminate any concerns that a variation in the curing environment may have played a role in impacting results.
