Expanded capacity from asset acquisitions involving two peer operators, coupled with recession-rooted market rationalization, have positioned Evanston, Ill.-based Concrete Specialties Co. as a pipe and drainage structure leader serving northeastern Illinois and southern Wisconsin, from Milwaukee to Madison. From its Chicago home base, the family-owned operator covers a 75- to 150-mile market radius for concrete pipe, manhole and box culvert with plants in Elgin, Franklin Park and Romeoville, Ill., plus Kenosha, Wis.
