Family-operated since 1952
The Dearth family has run this business for four generations.
That's the short version. The longer one explains why our crews care about your pour.
Our story
The Dearth family's history in business runs back to 1929 with Coal City Trucking — and into ready-mix in 1952 with Coal City Redi-Mix. Grundy Redi-Mix was established in 1985 (eventually absorbing the original Coal City operations), and River Redi-Mix was formed in 2004 with the purchase of the Marseilles plant. Today, Grundy & River Redi-Mix dispatches from nine plants across Grundy, Kendall, Kane, and LaSalle counties, working alongside our sister companies — Central Illinois Conveying, Coal City Trucking, and RTD Transport — to handle every part of a job from raw materials to finished pour.
In 2023, we entered a partnership with VCNA — Votorantim Cimentos North America, one of the largest cement and ready-mix producers in North America, part of the global Votorantim Cimentos group. The partnership brings additional supply network resources alongside the family operation that's served Illinois since 1952. Day-to-day, both Grundy and River remain family-operated by the Dearth family.
What we believe
- Phone first. Concrete is a phone-call business. Our dispatch desk in Morris answers when you call.
- Mix it right. Spec'd, batched, tested. IDOT-certified plants. ACI-certified field testers on staff.
- Show up on time. Most orders go in same-day or next-day. Large pours get scheduled with the crew that's actually doing the work.
- Stand behind the load. If there's a problem, we're a phone call away — and we know who you are because we wrote the ticket.
