NISC operates active limestone quarries producing both IDOT-certified and commercial-grade aggregates. Our materials are used in road construction, commercial site development, structural backfill, and more.

Recycling is a key part of our operations at Northern Illinois Service Co. We accept clean concrete, asphalt, and masonry debris at designated dumpsites, process the material, and resell it as affordable, sustainable aggregate options.

Open to contractors, municipalities, and the public.
