HOLMEN - County Materials' Holmen, Wis. pipe plant has earned a perfect score, for the second year in a row, in the state's annual Concrete Products Certification Program.
The plant inspection program is a joint effort between the Wisconsin Concrete Pipe Association (WCPA) and the Wisconsin Department of Transportation (WI DOT) for pre-cast concrete product manufacturers.
Under the extensive WCPA/WI DOT certification program, County Materials scored 100 percent in each of the 19 categories in both 2009 and 2010. Some inspection areas include Compressive Strength Tests, Quality Control Documents, Curing, Appearance, Handling & Storage, and Final Inspection & Loading.
County Materials' Rib Falls plant was the first pre-cast plant in Wisconsin to achieve this prestigious ranking in 2009.
The certification covers County Materials' full line of pre-cast reinforced concrete products, including storm sewer pipe, culvert pipe, elliptical pipe, cattle pass structures, manhole sections and structures, catch basins, box culverts, apron end walls and special structures.
Each plant is also inspected by an AASHTO certified engineer to check for compliance with applicable ASTM, AASHTO and WCPA standards and specifications. As certified plants, County Materials' Holmen and Rib Falls facilities are listed on the WI DOT approved product list.
The WI DOT recognizes the WCPA and two other national certification programs, including the National Precast Concrete Association (NPCA) and the American Concrete Pipe Association (ACPA). All three certification programs have similar requirements.
