Pipe reconstruction from the inside
The solution of today for water pipes of yesterday
Pipe reconstruction from the inside is an extremely cost-effective alternative to expensive and complex re-installation. As part of this process, the water pipes do not undergo a costly replacement, but are cleaned and permanently protected from the inside thanks to the application of a special coating.
There are no ripped-out walls or floors, and no notable impairment to normal building operations. No building site, and no dust or dirt.
How the RISAN® system works
After a thorough survey, analysis and assessment of the pipeline system, the water connections in need of renovation are made accessible.
Hot air is blown through the pipes in order to remove the residual moisture. This process already loosens the initial deposits, which are removed from the pipeline by the flow of air.
Quartz sand is now added to the compressed air. The sandblast removes the remaining deposits from the pipes, and grinds the inside of the pipes bare. This process is performed at all tapping points. The quartz sand is then extracted, and disposed of by specialists, together with the deposits.
The result of the sandblasting process is a bare inner tube, free from deposits, rust and limescale. Compressed air is then used to perform a leak test for the entire pipe network.
The coating material is then blown in, and a controlled flow of air used to coat the entire pipe network seamlessly from the inside. Corners and junctions are also coated evenly and seamlessly.
The end results of the pipe reconstruction from the inside: The drinking water pipes are renewed, and have long-lasting protection against limescale and rust, guaranteed by a 10-year warranty for as-new value.
