What iMPREG GmbH does

iMPREG GmbH is a German-headquartered manufacturer of CIPP (Cured-In-Place Pipe) liner systems for trenchless pipe and sewer rehabilitation, founded in 1999. The company specializes in UV-curing technology using proprietary fibreglass material, with its flagship GL16 liner covering pipe diameters from DN 150 to DN 2000 and a documented service life exceeding 50 years. The product portfolio is complemented by accessories including Glide foil, Safety caps, and Re-usable airlock, plus service offerings such as Training, Application Engineering, Rental park, and Consultancy.

The company sells primarily to municipalities and engineering offices, specialized sewer rehabilitation contractors, and industrial clients requiring large-diameter or non-standard pipe rehabilitation (including egg-shape combined sewers). It generates revenue through direct enterprise hardware sales of liner systems and accessories, with quote-based pricing typical for industrial infrastructure products; pricing is not publicly disclosed. Go-to-market is direct enterprise field sales from the Gärtringen, Germany headquarters, supported by wholly-owned regional entities — IMPREG LLC in the USA and IMPREG Suzhou Co., Ltd. in China — covering Europe, the Americas, and Asia-Pacific.

Since 2019, iMPREG has been backed by FSN Capital Partners. In January 2025, the company refreshed its top leadership with Frank Goede appointed as Group CEO and Guido Wey as Managing Director of IMPREG GmbH and EMEA, signaling a new strategic phase under continued PE ownership. Operating geographies span Germany, the United States, and China, and the company's UV-CIPP technology was deployed on the 2024 City of Encinitas Moonlight Beach project, recognized as the largest single-site large-diameter UV CIPP installation (855 linear feet of 72-in. liner) and runner-up for Trenchless Technology Project of the Year.
