The rehabilitation of non-man-entry sewer lines with full-length CIPP liners has established itself as a sophisticated economical and technical alternative to traditional repair techniques involving digging up the ground.
This method is meanwhile a proven and reasonable-cost solution for the basic renovation of service lines in need of repair and thus to extend their service lives for another life cycle of at least 50 years.
A basic condition is that the materials used in CIPP operations are suitable for this type of application and that the installation process meets stringent quality criteria.
Pipe run direction
- Manhole to Manhole application
- From the start point to the end point
- From the start point to the end point by running through an intermediate manhole
- From the start point into a sewer pipe run over a defined length without any further manhole or access pit needed
- In case of laterals: either from a lateral start point down to the lateral/main interface or from a main line start point down to the main/lateral interface
Circular, egg-shaped and special sewer sizes
- reinforced concrete
- GRP, PVC, PE, PP
- cast iron
- The cross section of the host sewer meets the process requirements and the structural stability criteria.
- Leaks with or without groundwater infiltration or exfiltration at pipe joints, pipe walls, junctions, transitions etc.
- Displaced pipes, cracks and debris, ruptures
- Plugging of lateral connections no longer needed
- Mechanical wear
- extreme pipe or joint offsets
- broken or collapsed pipes
- large cross-sectional reductions in conjunction with bedding problems
- longitudinal cracks at pipe connections
- DN 30 – DN 1200 | 1,2″ – 64″
