If mix designs are not provided for all concrete that will be used on the project, the reviewer may choose to identify the mix designs that still need to be submitted. The focus of a mix design review is on whether the mix design conforms to the requirements in the construction documents.
After careful location assessment, plants are erected on-site or adjacent to the project and are staffed by crews rigorously trained in dry mix plant operation. The result is a consistent, in-spec, high-quality concrete mix delivered continuously to meet the demands of every job and deadline.
