Directory of Accredited Laboratories


Construction Materials Testing


Accreditation is available for selected test methods in the areas of admixtures, aggregates, cement, concrete, geotextiles, road and paving materials, soil and rock, and steel materials. This accreditation program is designed to satisfy the requirements of contractors, state and local governments, and federal agencies specifying accreditation for construction materials testing laboratories.

The test methods for which a laboratory may seek accreditation are listed in NIST Handbook 150-5. Other test methods may be added to the program upon request, if they are found to be appropriate by NVLAP.


Listed below are all laboratories accredited within this program as of July 3, 2008. For additional information, contact NVLAP at (301) 975-4016.
