Lannon Stone Products

What Lannon Stone Products does

Lannon Stone Products, Inc. is a family-owned construction aggregates producer operating six quarries and pits across Southeast Wisconsin (Sussex, Lannon, West Bend, Richfield, Jackson, and Ottawa). Founded in 1967 and currently employing 11-50 people, the company mines hard dolomitic limestone from four quarries (Sussex/West, Lannon, Jackson, Lisbon) and glacial-till sand and gravel from three pits (Lisbon, Richfield, Dousman). Its product portfolio spans High Strength Aggregates, washed Concrete Aggregates, Asphalt Aggregates, Structural Backfill, Rip-Rap, Clear Drain Stone, State Spec Base Course, Sand (including concrete, beach, manufactured, bedding, and golf course grades), Agricultural Limestone, and WI DNR-compliant Type B and Type C Pond Liners. Processing capability includes a custom automated wash plant at Lisbon Pit (washing, scrubbing, rinsing, sand blending, maximized p200 removal) and waterless dust control technologies deployed since 2017. Specification compliance claims include >75% fractured faces, near 0% friable particles, and conformance to Wisconsin DOT and AASHTO specs.

The company monetizes through one-time per-ton sales of aggregates to concrete producers, asphalt producers, road builders, grading/utility contractors, and landscape/environmental contractors, supplemented by clean-fill tipping fees at the Moraine Development (Richfield) and Jackson Clean Fill Tipping Sites under WI DNR 500.08(2)(a). Distribution combines direct quarry/pit pickup by contractors with a network of eight retail distributors serving general-public/DIY buyers. Delivery is provided through wholly-owned Certified Truckers, operating 60 Class 8 quad-axle dump trucks with a 10-ton private-delivery minimum, dispatched via 262-251-1520. GTM is sales-led, supported by a company website, an online product-calculator tool, an SDS/credit-application resource library, and Paycom-based hiring. The Dawson family resides in the host communities (Village of Richfield, Town of Lisbon, Village of Sussex), and the firm tithe 10% of annual profit through the Lannon Stone Foundation to local charitable causes. Pricing is not publicly disclosed; quotes are handled by phone. The company has no institutional investors, no public listing, and no disclosed revenue.

Direct peers

• Kraemer Mining & Materials: Family-owned aggregate producer headquartered in Wisconsin/Upper Midwest mining dolomitic limestone and sand & gravel. Operates multiple quarry/pit locations across Minnesota and Wisconsin, making it the closest direct competitor to Lannon for both geology and regional end markets in concrete, asphalt, and DOT base course.
• Payne & Dolan: A Wisconsin-based aggregate and asphalt producer serving the Greater Milwaukee and Madison markets. Closely competes with Lannon for asphalt aggregate tonnage, base course, and road-building contracts under Wisconsin DOT specifications.

Broad incumbents

• Vulcan Materials Company: The largest producer of construction aggregates in the United States, operating hundreds of plants nationwide. Vulcan competes with Lannon for large Wisconsin DOT and infrastructure bids and serves as the bellwether benchmark for aggregate pricing, margins, and reserves economics.
• Martin Marietta Materials: A top-three US aggregates producer with a heavy footprint in crushed stone, sand, gravel, and ready-mixed concrete across the Midwest. Comparable business model centered on quarrying hard rock and serving DOT/infrastructure demand, though at vastly greater scale than Lannon.
• Lehigh Hanson: A major Heidelberg Materials subsidiary operating aggregate, cement, and ready-mix concrete plants across North America. Competes with Lannon for large Wisconsin infrastructure bids and shares a dolomitic limestone product portfolio.
• Aggregate Industries (US): A Holcim-owned aggregates, asphalt, and ready-mix concrete operator in the US Midwest. A broader incumbent that competes with Lannon for large DOT and commercial infrastructure projects in overlapping regional markets.

Regional players

• Michels Materials: Wisconsin-based division of Michels Corporation operating quarries producing crushed stone, sand, and gravel for Midwest construction markets. Overlaps with Lannon on limestone aggregates and concrete stone serving Southeast Wisconsin contractors.
• US Aggregates: A Midwest-focused aggregate producer operating limestone and sand/gravel pits serving Indiana, Ohio, and adjacent states. Most comparable to Lannon in scale (single/dual-state footprint) and in dolomitic limestone product mix for concrete and asphalt end uses.
