Today, brown, rusty water comes out of your water pipe, and tomorrow, clean, clear water of the best drinking quality will flow. Sounds almost like magic, but it really does. Thanks to our certified RISAN®system. Guaranteed.
The pipes are cleaned from the inside and then sealed with the special coating developed and produced by us. In this way, we guarantee years of service life for your drinking water pipes.
The advantages are obvious: the water pipes do not have to be replaced and there is no dirt and grime. The regular building operation can continue unrestricted, because: We renovate drinking water pipes without an installation site.
After emptying the installation, the pipes are dried with hot air.
The pipes are cleaned purely mechanically with air and sand. The sandblast completely detaches the deposits from the pipes and grinds the inside of the pipes. This process takes place at every tap. At the end, the quartz sand is extracted and disposed of together with the deposits.
Finally, the RISAN® coating material is blown in as a thick solution and the entire pipeline network including angles and branches is coated evenly and seamlessly from the inside using a controlled air flow. The coating is dried with hot air within a few hours. After that, the pipeline can be put back into operation immediately.
The end result of the pipeline renovation from the inside: The drinking water pipes are new again and protected against limescale and rust in the long term. We insure this with a new value guarantee of 10 years.
