LABORATORY TESTING

MMT has two offices in Clark County, NV and each in-house laboratory is AASHTO R18 accredited by Construction Materials Engineering Council, Inc. (CMEC) who a Nationally recognized accreditation body is and has been recognized by the National Cooperation for Laboratory Accreditation (NACLA).

With our highly trained professional and technical staff, we have quick turn-around times for test results which ultimately reduces the chance of major problems arising.  Our laboratories are accredited to run the following test:
