Milestone Materials

What Milestone Materials does

Milestone Materials, a division of the family-owned Mathy Construction Company, is a regional aggregate materials supplier headquartered in Onalaska, Wisconsin. Founded in the early 1960s, the company produces stone, crushed stone, sand, and gravel materials used in building, maintaining, and beautifying infrastructure for communities, businesses, farms, and homes across Wisconsin, Minnesota, and the Upper Peninsula of Michigan. The company also operates four retail Landscape Supply Centers in La Crosse WI, Tomah WI, Baraboo WI, and Rochester MN, serving homeowners and small contractors with landscaping stone, mulch, decorative rock, driveway base, sand, and topsoil.

The production platform combines fixed quarry operations with state-of-the-art mobile equipment—portable crushers, screening plants, and on-site wash plants—delivered to customer job sites for project-specific aggregate production. An in-house quality control laboratory tests products to industry specifications, and a separate specialized research facility staffed by chemists and engineers conducts asphalt pavement and aggregate R&D, including work on green technologies. Beyond core construction aggregates, the company offers railroad ballast (crushed granite, traprock, or quartzite in 1"–2.5" sizes), Corps-of-Engineers-spec riprap for erosion control, agricultural lime and farm products certified to National Organic Program standards, and recycling/disposal services that convert salvage concrete, asphalt, and shingles into reusable road base. Materials are produced to ASTM and AASHTO specifications and are pre-qualified with Wisconsin, Minnesota, Michigan, and Iowa Departments of Transportation. A public Volume Calculator on the website allows customers to estimate aggregate quantities from length, width, and depth inputs.

Revenue is generated through quote-based bulk aggregate sales to contractors, direct trucking and delivery using an in-house fleet of dump trucks (15–22 ton capacity), project-based custom crushing and washing services, retail over-the-counter transactions at the four Landscape Supply Centers, and recycling/disposal tipping fees. The customer base is segmented across civil engineers and government infrastructure projects (DOTs, public works), landscape architects and homeowners (retail), farmers (agricultural lime), and railroads (ballast). Headcount is reported at 101–250 employees, revenue is not publicly disclosed, and the company operates as a private division within the Mathy Construction Company corporate umbrella with a stated tradition of community involvement for nearly 75 years, including quarry land reclamation partnerships with the Mississippi Valley Conservancy and Legacy Trees.
