With almost 100 years of experience in cement and concrete technology, CTLGroup can handle all physical and chemical testing needs. We offer both standard and specialized tests of portland cement, blended cement, masonry cement, pozzolans, fly ash, slag, grout and other cementitious materials. State-of-the-art laboratory equipment, including automatic mixers from Toni Technik and an automatic Vicat time-of-set machine, helps us deliver fast, accurate results.

Our long participation in the CCRL sample proficiency program and CCRL’s inspection of our equipment and procedures help us maintain high quality standards. Our lab is also AASHTO accredited.
CTLGroup can evaluate questionable or contaminated material and provide litigation support. We offer precise, consistent and timely data reporting. Interim test results are available by e-mail, fax or phone, and final reports are usually issued within a day after all tests are complete. Rush service also is available.
