IMPREG GmbH

IMPREG GmbH operates as a manufacturer of pipe liner systems designed for trenchless pipe and sewer rehabilitation. The company was established in 1999 when an investment group of six shareholders founded IMPREG Holding ApS, selecting Germany as the production location due to its core market status. One of the co-founders was Robert Papp, who was instrumental in the company's shift from steam-cured liners to UV-cured liners, a move that significantly propelled the company's growth. Papp's technical expertise and persistence are recognized as key factors in establishing the IMPREG liner as a benchmark for quality in trenchless sewer rehabilitation.

The company's business is centered around the production and global distribution of fiberglass-reinforced, UV-cured-in-place pipe (CIPP) liners. This technology allows for the rapid and economical repair of damaged sewer mains and wastewater pipes without the need for extensive excavation, minimizing disruption to traffic and the surrounding environment. IMPREG's revenue is generated through the sale of these CIPP liner systems to a client base that includes contractors, installers, and municipalities worldwide. The business model focuses on providing a durable product with a service lifespan of over 50 years, supported by technical and after-sales service.

IMPREG's flagship product is its CIPP liner, such as the GL16 model, which is composed of a unique fiberglass fabric complex. These liners are inserted into damaged pipes and then cured using UV light, a process that is significantly faster than conventional methods and allows pipes to be returned to service almost immediately. A key feature is their versatility; they can be manufactured for a wide range of pipe diameters, from DN 150 up to DN 2000, and can accommodate dimensional changes, bends, and various forms of degradation. The company has expanded its global footprint with manufacturing facilities in Germany, the USA (since 2019), and China (since 2017), as well as warehouses in the UK and California to ensure shorter lead times for its customers. In November 2019, private equity firm FSN Capital acquired the IMPREG Group to support its continued global expansion and technological development.
