What National Liner does
National Liner, founded in 1992 and headquartered in Pewaukee, Wisconsin, is a private for-profit supplier serving the cured-in-place pipe (CIPP) rehabilitation industry. According to the company's own positioning, it provides the products, materials, and technical knowledge that qualified CIPP installers rely on for trenchless pipe repair projects. The company operates with a very small team of 1-10 employees and has no publicly disclosed ownership, investor backing, or parent company relationships.
The business model centers on supplying CIPP installation materials — which typically include resin-impregnated liner tubes, calibration hoses, and related consumables — to specialty contractors performing trenchless sewer and pipe rehabilitation. National Liner's value proposition combines physical product supply with technical knowledge transfer, suggesting a consultative, technical-sales approach targeting a narrow installer base rather than commodity distribution at scale. No pricing model, customer list, certification, or partnership information was available in the source data, leaving the full product mix, customer segmentation, and revenue mechanics unverified. The 30+ year operating history is the only durable signal of business continuity in the available evidence, and the company's own website returned only a loading/verification placeholder, preventing deeper extraction of product, customer, or operational details.
