NISC was founded in 1970 by Wayne Klinger. Originally, the company began as a demolition and site work contractor. In the years since, we have grown to include quarries and concrete recycling services, a complete staff of office and field employees, and a service area that includes Northern Illinois and Southern Wisconsin. Our growth has been calculated and deliberate, expanding in ways that strengthen our company, rather than being rapid and unsustainable. We specialize in demolition, earthwork, underground construction, concrete and asphalt recycling, commercial and industrial site work, and design-build services.
