With a catalog of hundreds of active mix designs, Hi-Grade Materials is able to meet specific needs of contractors and engineers alike. Performance and Specification driven mixes are tailored to structural requirements and each mix is heavily evaluated by Hi-Grade Materials Quality Control to make certain that criteria are met.
Materials that enter Hi-Grade Materials plants, from aggregates to fly ash, are tested to ensure proper quality and consistency of product. Random loads of ready-mix are tested for strength/time properties, slump, air entrainment, unit weight and yield, and cylinder strength throughout the various stages of Hi-Grade Materials quality assurance.
All Hi-Grade Materials plants are NRMCA certified.
