Wie die Inversionssanierung funktioniert
Inversion sanitation is a trenchless pipe restoration method that allows you to create a new pipe inside an old one without excavation and dismantling. In this article, we will analyze in detail the physics of the process, the stages of operation of the SPI:RES system and answer the questions that our customers most often ask. If you want to understand exactly how technology is changing the rules of the game in sewer system repair, this material is for you.
WHAT IS INVERSION SANITATION?
Inversion (from Latin inversio — inversion) is the process of turning a flexible sleeve (liner) under pressure inside a damaged pipeline. Unlike traditional broaching methods, where the material is simply dragged through the pipe, inversion allows the liner to fit snugly against the walls, repeating all bends and irregularities, including branches and joint zones.
The SPI:RES system uses this method, complementing it with intelligent control and parameter monitoring in real time.
STAGE 1: PREPARATION AND DIAGNOSIS
Inversion (from Latin inversio — inversion) is the process of turning a flexible sleeve (liner) under pressure inside a damaged pipeline. Unlike traditional broaching methods, where the material is simply dragged through the pipe, inversion allows the liner to fit snugly against the walls, repeating all bends and irregularities, including branches and joint zones.
KEY LEARNING OUTCOMES:
- Your employees work confidently with the SPI:RES system
- The human factor is eliminated due to the understanding of automated processes
- Improving customer service quality
- Official certification of specialists

STAGE 2: BROACHING THE LINER IN A STRAIGHT POSITION
Inversion (from Latin inversio — inversion) is the process of turning a flexible sleeve (liner) under pressure inside a damaged pipeline. Unlike traditional broaching methods, where the material is simply dragged through the pipe, inversion allows the liner to fit snugly against the walls, repeating all bends and irregularities, including branches and joint zones.
