The Trelleborg LCR-S method
The Trelleborg LCR-S system is an essential method and cost-saving tool to repair and permanently seal main/lateral interfaces and connections from the main line (DN 135 - DN 600) down into the lateral (DN 100 - DN 200)
Smart tools to assist you
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.
Absolute process control
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.
Save installation through control mechanisms
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.
Curing at ambient temperatures
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.

How the Trelleborg LCR-S works
The Trelleborg LCR-S system permanently seals main/lateral interfaces and lateral connections (DN 100 – DN 200) by installing either a LCR-S hat profile or an LCR-S liner from the main pipe (DN 135 – DN 600) up to a length of 600 mm.
after
Repaired lateral pipe
The infiltration is stopped, the pipe is watertight.
The length of public owned drainage pipes - just in Germany is more than 500 000 km
Approx. 20% - more than 100 000 km - need renovation
To maintain the network around 7 billion Euros need to be invested annually.
The length of private property drainage pipes - just in Germany is approximately
1 000 000 km - more than 40% defect
Property entails obligations!
