Seal of Quality Concrete



The granting of a Seal of Quality Concrete or a Seal of Special Quality Concrete is restricted to RMCAO members who possess a valid “Certification of Ready Mixed or Mobile Mix Concrete Production Facilities”.

How it Works

A Seal of Quality shall be granted for one (1) year from the date of RMCAO Facility Certification. Applications for a seal of quality in the proceeding year must be based on new test data that is within 12 months of the date of the application. Application for a Seal of Quality Concrete or a Seal of Special Quality Concrete may only be made for a plant currently producing concrete.
