Hartman Walsh Industrial Services

What Hartman Walsh Industrial Services does

Hartman Walsh Industrial Services (legal name Hartman-Walsh Painting Co) is a privately held, national union industrial painting and coatings contractor founded in 1950 and headquartered in St. Louis, Missouri, with a workforce of 400+ serving clients across the United States and Canada. The firm applies protective coatings, linings, fireproofing, and lead-abatement solutions to petrochemical, power-generation (nuclear, hydroelectric, geothermal, coal-fired), government, and general industrial assets, holding AMPP/SSPC QP1, QP2, QP8, and QS-1 certifications that prequalify it for federal and complex industrial work with agencies such as the Bureau of Reclamation, U.S. Army Corps of Engineers, DOE, and DOD.

The company's distinctive technical asset is a proprietary robotic Spray-in-Place Pipe (SIPP) system developed across multiple iterations to line pipe diameters from 4 inches to 24 feet, including hydroelectric penstocks, using fiber-optic-controlled umbilicals and Coriolis flow meters to hold precise wet/dry film thickness. The SIPP platform has supported more than $200M in completed penstock and trenchless pipe-rehabilitation work with a $100M backlog, and delivers roughly 40% cost savings versus direct pipe replacement while reducing material waste to single digits (compared with 15-20% for manual application). Supporting capabilities include surface preparation (sandblasting, abrasive blasting), intumescent and cementitious fireproofing, tank linings, and hazardous-paint removal, executed by NACE CIP-trained painters and an in-house engineering team of eight degreed engineers.

Hartman Walsh generates revenue primarily through project-based professional services contracts, split roughly 50/50 between lump-sum fixed-price work and Evergreen (cost-plus/time-and-materials) engagements, with approximately 80% of volume from repeat customers. The go-to-market is enterprise field sales: direct engagement with industrial owners, general contractors, and government agencies supported by competitive bidding, a Top 10 ENR ranking, and a documented safety record (0.74 EMR, 0.58 TRIR, 0.40 LTIR). Marketing emphasizes certification depth, safety performance, and technical expertise via the company website, project case studies, and light organic social presence.

Revenue model

1. Industrial Painting and Coating Services: Project-based professional services revenue from industrial painting, coating, and lining services. Work includes surface preparation (sandblasting, abrasive blasting), application of protective coatings (epoxy, urethane, intumescent), tank linings, penstock rehabilitation, and fireproofing. Revenue derived from both lump-sum fixed-price contracts and Evergreen-type (cost-plus/time-and-materials) arrangements.
2. SIPP (Spray-in-Place Pipe Lining): Specialized pipe rehabilitation services using proprietary robotic technology for epoxy lining of existing pipes. Delivered as standalone service or part of broader coating contracts.

Core offering

Hartman Walsh Industrial Services is an industrial painting and coatings contractor that delivers surface preparation, application of protective coatings (epoxy, urethane, intumescent), tank linings, penstock rehabilitation, lead abatement, and fireproofing for power plants, petrochemical facilities, government installations, and industrial infrastructure. The company operates proprietary robotic Spray-in-Place Pipe (SIPP) lining technology for trenchless pipe rehabilitation and serves enterprise and government clients across the United States and Canada.

Product overview

Hartman Walsh Industrial Services is a industrial painting, coating, and lining services company established in 1950, offering over 75 years of experience. The company operates as a single unified service offering centered on protective coatings and industrial rehabilitation. Its core portfolio consists of five interconnected services: Tank Coatings and Linings (for storage and process tanks), Penstock Repair and Rehabilitation (hydroelectric infrastructure using proprietary robotic SIPP technology), Spray-In-Place Pipe Lining (trenchless pipe rehabilitation for diameters 4"-36"), Lead Abatement Services (hazardous paint removal), and Intumescent/Cementitious Fireproofing (passive fire protection). Supporting these are surface preparation services (sandblasting/abrasive blasting). The company primarily serves power (nuclear, hydroelectric, geothermal, coal-fired), oil and gas, chemical, government, and manufacturing sectors across North America and Canada.

Functional benefit

Products and services

• Tank Coatings and Linings Protective coatings and linings for external and internal surfaces of steel storage tanks, process vessels, water tanks, chemical tanks, and fuel tanks. Includes epoxy, vinyl ester, novolac, high solids, and phenolic linings for chemical resistance, abrasion resistance, and potable water compliance for industrial facility owners.
• Penstock Repair and Rehabilitation Robotic spray-in-place pipe lining (SIPP) technology for rehabilitating large and small diameter penstocks and steel pipes in hydroelectric power plants. Uses unmanned robotic systems with epoxy resinous coatings, monitored via fiber optic control room systems, reducing material waste to single digits.
• Spray-In-Place Pipe Lining (SIPP) Trenchless pipe rehabilitation technology using robotic systems with precision spray heads to apply epoxy coatings within existing pipes. Eliminates excavation needs, works on pipe diameters from 4 inches to 36 inches, delivers approximately 40% cost savings versus pipe replacement. Suitable for water mains, sewer lines, and potable water systems.
• Lead Abatement Services Industrial lead paint removal and remediation services using HEPA filtration equipment, complying with EPA, OSHA, and HUD standards. Includes encapsulation techniques and simultaneous lead and asbestos hazard management for industrial facilities.
• Cementitious and Intumescent Fireproofing Passive fire protection for structural steel using intumescent coatings that expand under high temperatures to form insulating carbonaceous char, plus cementitious coatings for cost-effective protection. Includes water-based, solvent-based, and epoxy-based intumescent coatings meeting ASTM E119 standards.
• Surface Preparation (Sandblasting and Abrasive Blasting) Surface preparation techniques including sandblasting and abrasive blasting to ensure optimal coating adhesion and durability for industrial painting projects. Provided as a supporting service in conjunction with coating application.
