HMI

What HMI does

HMI Company is a privately held, US-based manufacturer and service provider specializing in concrete lifting and soil stabilization solutions. Founded in 1974 and headquartered in Manitowoc, Wisconsin, the company sells pro-grade polyurethane concrete raising systems, hydraulic mudjacking equipment, void filling and soil stabilization equipment, and a portfolio of proprietary consumable materials — including polyurethane foam (made with over 40% recycled content), Deep Foamjection™, FILLFOAM™, Soil Link Grout, and Ionic Clay Stabilizer. HMI invented the first hydraulic mudpump over 45 years ago and positions itself as a pioneer of the mudjacking category.

The company's business model combines four revenue streams: one-time equipment sales (turnkey truck- and trailer-mounted systems), recurring consumable materials revenue tied to contractor usage, paid training services (notably a 2-Day Discovery & Training Seminar plus a Soil Improvement Seminar), and equipment financing for new entrants. Go-to-market is predominantly direct-to-contractor with phone-based sales, on-site project support, and an owned contractor referral network at Foamjection.com, supplemented by a self-serve e-commerce shop.

HMI serves four primary customer segments — Residential, Commercial, Government (highways, municipalities, D.O.T., airports), and Industrial (railroads) — through the end-buyers of its equipment: independent contractors and entrepreneurs, many of whom are first-time business owners entering the concrete raising trade via HMI's turnkey bundle. End-applications span sidewalk, driveway, warehouse floor, parking lot, foundation, seawall, and roadway settlement repair. The company markets itself as 'Built FOR contractors BY Contractors,' emphasizing that its products are field-tested in its own daily operations.

Direct peers

• Polylevel: Polylevel provides polyurethane foam concrete raising services and equipment/contractor support, directly competing with HMI in the same end markets (commercial, residential, municipal) and offering similar proprietary foam materials.
• Alchemy-Spetec: Alchemy-Spetec manufactures and sells polyurethane foam materials and equipment for concrete lifting, soil stabilization, and void filling — directly overlapping with HMI's core polyurethane concrete raising business and serving the same contractor / infrastructure customer base.
• URETEK USA: URETEK ICR (and its U.S. licensee) is a direct competitor in polyurethane concrete lifting and deep foam injection for infrastructure, roadways, and commercial/industrial applications, offering its own proprietary foam and equipment line.

Emerging players

• Aerix Industries: Aerix Industries manufactures engineered polyurethane foam products for construction and geotechnical applications including void filling and slab lifting, making it a niche emerging competitor with overlapping technical offerings to HMI.
• SealBoss: SealBoss provides polyurethane injection resins, grouts, and concrete repair products for waterproofing and structural repair, with partial overlap to HMI's polyurethane foam, soil stabilization, and void filling applications.

Broad incumbents

• NCFI Polyurethanes: NCFI is a large, established manufacturer of polyurethane foam systems for construction, insulation, and geotechnical applications; while not focused exclusively on concrete lifting, it competes in the supply of polyurethane raw materials and formulations that drive HMI's material business.
• Fox Industries: Fox Industries manufactures specialty construction products including chemical grouts, sealants, and concrete repair materials used in infrastructure repair, overlapping with HMI's Soil Link Grout and concrete repair material lines.
• BASF Master Builders Solutions: BASF's Master Builders Solutions division supplies specialty construction chemicals and materials used in concrete repair and soil stabilization; it is a much larger incumbent that competes for specification in the same infrastructure and commercial repair projects where HMI's foam and grout products are used.
