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. 

The resin systems used in the LCR-S process are ambient curing - this means that you do not need additional technical equipment for heat supply.

Long processing and short curing times increase safety of working and lead to better results. In addition, they are environmentally friendly and styrene-free. In combination with the glass-fiber reinforced carrier material, you will achieve excellent mechanical properties and a sustainable rehabilitation result.

The method repairs different circular pipes

• 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

Good practice-oriented training of our installers is a major concern for us and a component of our quality management approach.

Only qualified professionals with training are permitted to use our systems. Qualified personnel will be issued with a training certificate by Trelleborg Pipe Seals.
