What Wendling Quarries does

Wendling Quarries Inc. is a privately held, family-oriented construction aggregates producer founded in 1987 and headquartered in DeWitt, Iowa. The company mines, crushes, and distributes crushed limestone, sand, gravel, premium topsoil, and recycled concrete and asphalt products (marketed under the Greenstone brand) to commercial and residential construction customers across Central and Eastern Iowa and Western Illinois. Beyond raw materials, Wendling operates a service arm — mine services, contract drilling, and custom crushing — offered to third parties across the Upper Midwest. The company also runs two branded specialty extensions: Redline Sand and Sports Turf Products, supplying USGA-spec sand and specialty blends to golf courses and athletic facilities (backed by affiliations with the Golf Course Superintendents Association of America and the Sports Field Management Association), and Wendling Landscape Products, a wholly-owned subsidiary with four dedicated landscape yard locations in the Cedar Rapids area serving residential and commercial landscaping demand.

Revenue is generated through unit-priced, transaction-based sales of aggregates, with delivery charged by quantity and mileage and no minimum delivery load size. A credit account program — purchases due by the 20th of the following month, with service charges on past due balances after 30 days — provides a recurring commercial billing layer on top of one-time cash, check, and credit card retail transactions. Customer segments are diversified across commercial and residential construction (primary), golf and sports turf (vertical specialty), and landscaping (SMB/consumer). Go-to-market is direct: pickup at any of numerous quarry, sandpit, and landscape locations; delivery to homes and job sites; phone-based sales; and a corporate website with online material estimator tools.

Operationally, the company reports a catalog of 100+ crushed limestone, sand & gravel, and recycled concrete products, recycles the equivalent of more than 30 miles of highway pavement annually through Greenstone, and runs a long-tenured leadership team led by Chairman & CEO Tony Manatt and President Kaleb DiRico, supported by functional VPs in administration, sales, and operations. The company is privately held with no disclosed institutional investors, no funding rounds, no acquisitions or divestitures in the available record, and no public revenue disclosure.
