Lateral connection repair in main sewer pipes

• The exact determination of the damaged area and the correct positioning of the packer is the precondition for a successful installation.
• The packer is therefore equipped with a camera, a telescopic wheel system and a rotary drive for utmost maneuverability and orientation in the pipe. 
• A special designed lifting  mechanism, called "pathfinder", supports the correct positioning inside the sewer pipe at the damaged lateral connection.

• The monitoring camera installed on the packer assists in the positioning process. 
• Once the LCR-S packer has reached the junction, the mouth piece of the LCR-S hat profile or LCR-S liner can be turned by means of the push rod reel system for proper alignment with the branch. 
• You can monitor and control all operations with the external control unit. 

The control mechanisms built into the system ensure the highest possible level of security and a high quality result:

• Starting the inflation process is possible only after the lateral hose is locked in place. 

• When the lateral packer hose has been completely inverted, a clear acoustic signal is given to indicate that the inversion process successfully is finalized. 

Main Pipe Diameters

The method repairs circular pipes of 

• asbestos cement
• cast iron
• concrete
• plastics (HDPE, PVC, GRP)
• reinforced concrete
• vitrified clay

• Leaks with or without groundwater infiltration or exfiltration at pipe joints, pipe walls, junctions, transitions, etc.
• Displaced pipes, cracks and debris, ruptures
• Mechanical wear
• Corrosion

• extreme pipe or joint offsets
• broken or collapsed pipes
• large cross-sectional reductions in conjunction with bedding problems
• longitudinal cracks at pipe connections
