The RISAN®based in Starnberg, Germany, specialises in the non-destructive rehabilitation of drinking water pipes in buildings using state-of-the-art technology. The RISAN®system is distributed and used throughout Europe and is suitable for any type of property; from single-family homes and apartment complexes to hospitals, hotels, schools, retirement homes and other public or commercial facilities.
With decades of experience, the process of pipe interior rehabilitation has been continuously developed and optimised to ensure maximum safety for your drinking water and installations. The coating materials for pipe rehabilitation from the inside were developed by RISAN® adapted to the current drinking water hygiene laws. The RISAN®system thus also guarantees long-term resistance at continuous operating temperatures above 65°C with a new value guarantee of 10 years! Due to the extremely short curing time of only 8 hours, the RISAN®-system does not impose any significant restrictions on your everyday living and working life. Without construction site and dirt, the rusted drinking water pipes of your property are renewed from the inside in the shortest possible time, with a cost saving of up to 50 % compared to a conventional total replacement of the water pipes. The RISAN® Coating material (German Quality) meets the strict requirements for drinking water in cold and hot water areas. (Status certifications 2020)
