Trelleborg DrainLCR-S

Method for the Sectional Renovation of Lateral Junctions and Pipes in the Main Sewer Line

Main pipe: DN 130 to DN 600
Lateral pipe: DN 100, 125, 150 and 200 at 30° to 90°

The DrainLCR-S system is used to repair and permanently seal main/lateral interfaces and connections up to 500 mm from the mainline down into the lateral.

The system can use either an LCR-S hat profile or an LCR-S liner.

The main-to-lateral interface in the main pipe is sealed only by the rim of the LCR-S hat profile, while the LCR-S liner in the main pipe is designed as a short liner.

Benefits:

Reliable to install:
1. Inversion is not possible until positive engagement of the pathfinder.
2. The signal will not sound until complete inversion.
Technical advance: Only the inversion process allows pipe bends and offset joints to be relined.
Meets practical needs: Successful repairs are possible with little equipment needs only, even in the presence of groundwater.
Price advantage: Low investment cost, because you need to buy just the packers actually required.
Practical: The low-weight mobile unit with low space requirements can be placed even in a small car.
Flexible: It is also possible to use air push rods or a carriage.
Accessibility: The LCR packers can be folded as required inside the manhole.
User-friendly equipment: The LCR packers can be converted to other sizes as required.
