NPCA’s Plant Certification program is dedicated to increasing the quality of precast concrete products and assisting specifiers in obtaining those products. Since 1987, NPCA experts have helped businesses like yours to continually monitor, manage and improve the quality of their products.


The initial cost of plant certification is minimal when compared to the benefits of focusing on quality control in the plant. We can document savings in raw materials and purchased items, fewer damaged or rejected castings, and reduced labor and rework of products on the job site. This precast certification program corrects plant errors before they become high-cost problems.
