Vertical Challenge Restoration Article from CoatingsPro Magazine
It takes a lot of flour to satisfy America's hunger for crackers, cookies, cereal, frozen pizza, and other treats. So when the world's largest production flour mill needed major restoration on 28 storage silos. the wanted a coatings company they could count on.
The Nabisco Kraft flour mill in Toledo, Ohio processes more than 80 percent of all the flour used by Nabisco and Kraft, which merged in 2000 to become one of the country's largest food manufacturers. The food maker's grain-milling operation depends entirely upon square-shaped 1950's-era concrete bins, each 73 feet tall. Eight and a half feet square at the base, the silo-like bins are the company's lifeline, holding and transporting more than five million pounds of flour per day.
One of the last things a mill operator wants to find is chips of coatings or concrete appearing in their flour. Nabisco Kraft's Quality Chain Management System (QCMS) protects and controls food safety and the quality of the products they deliver to customers. QCMS is based on the structure and general requirements of International Organization for Standardization (ISO) 9001:2000, but supplemented with food safety and quality needs specific to the flour milling business.
Preventative measures embedded in the system alert grain-mill operators when issues arise. Corrective action, based on root-cause analysis, is swiftly implemented. Bins receiving the new round concrete liners would receive initial coatings within 24 hours - a far cry from the
28 - day norm.
Installers and Corroshield teamed up to keep the world's largest flour mill in operation. Nabisco Kraft Plant managers are so delighted with the outcome, they recently asked Smith to a meeting to discuss doing another project.
New Meat Cooler Floor, Coating Packed into 4 Days - PaintSquare Article
When a food packing company needs a new floor in its cooler, timing can be critical, to the point of needing to coat green concrete. Such was Momence Packing Company’s dilemma
when it took on the replacement of a concrete floor that had failed due to heaving, or buckling, from thermal cycling, says Ed Petras, senior engineer for the plant. The floor is exposed to temperatures of 0 to 15 F (-18 to -9 C).
After removing the damaged concrete floor, the contractor’s crew placed the heated tube system (above) and installed a new, four-inch concrete floor over the tubing (inset).

In addition, the floor supports 1,000-pound racks of meat that are moved by forklift in and out of the cooler as part of the packing process. The Momence, IL-based packing company had tried different mixes of concrete, various epoxy floor coverings, and several patching materials, but each approach led to failure. “The coatings would last six months and then heave,” says Petras.
