What Wk Construction Co does

W K Construction Company, Inc. is a privately held heavy highway construction contractor founded in 1982 and headquartered in Middleton, Wisconsin. The company operates two integrated divisions: a pavement construction services line (asphalt and concrete milling, cold in-place recycling with both emulsion and foamed asphalt, pulverizing, and full depth reclamation) and a quarry products subsidiary called W K Stone, which operates a limestone quarry and sand pit producing certified crushed stone, sand, and agricultural lime. Equipment capabilities include specialized milling machines with 3D/total station profile controls, pulverizers with state-of-the-art injection systems for foamed asphalt, emulsion, water, or chemical stabilization, and a full support fleet of water trucks, skid loaders, brooms, and vacuum sweepers.

The company generates revenue primarily through project-based heavy highway construction contracts with state departments of transportation, county highway departments, municipal public works agencies, and airport authorities across Wisconsin, Illinois, Iowa, Michigan (Upper Peninsula), and Minnesota. A secondary product-revenue stream comes from W K Stone, which sells and delivers certified aggregate materials meeting Wisconsin DOT and City of Madison specifications, as well as UW-Soils-tested agricultural lime products to farm operations. Customer acquisition is conducted through direct contact-driven sales via the company website, supported by industry association memberships and reputation-based bidding on public infrastructure tenders.

The business is privately held with no external funding disclosed, no parent company, and an ownership structure that is unspecified in the public data. The company employs roughly 93 people with seasonal staffing peaks between May and October, reports low employee turnover, and has been operating continuously across multiple states for over four decades with no public M&A, funding, or leadership changes disclosed in the available data.
