SHARE

The punctual rehabilitation is a special kind of cured in place pipes (CIPP). The liner seals different damaged spots like rifts, untight sockets and holes and also stops each intrusion of infiltrating water reliably. Additionally, the procedure of punctual rehabilitation is the optimal solution to balance shifted pipes, or to close blind inflows.The glassfibre fleece saturated with resin is installed via installation shaft (manhole) using a Bypasspaker, a rope and TV-monitoring the glassfibre fleece is pulled to the damaged spot. The Parker is blown up with ca. 1,0 bar and pressed against the pipe wall.
