The Trelleborg LCR-B method
Leaking downpipes and sewers in buildings still typically mean bad smells for the residents and can, in the worst case, result in structural damage and moist walls or even mouldiness.
Conventional repair methods – breaking up walls and/or grounds – then make people suffer noise, dirt, and service disruption. Trelleborg Pipe Seals remedy this problem:
The Trelleborg LCR-B repair method repairs laterals without breaking out walls or excavations, which means much less annoyance to residents.
How it works
The Trelleborg LCR-B is a pipe repair device or method for rehabilitating in-house down-pipes and underground sewers.
In this innovative method, the repair unit - the so-called packer - is inserted in the existing access holes, chambers, or eyes of the rainwater or wastewater down-pipe and sewer and pushed to the point of repair utilizing compressed-air pushrods.
Highly flexible material
As the LCR-B packer is highly flexible, it will smoothly negotiate 45° elbows in a DN 100 main pipe and even 90° elbows in lines of DN 125 or more.
An inspection camera is placed into the branch line and pushed up to the main/branch interface.
Once the LCR-B packer has reached the junction, the mouthpiece of the LCR-B hat profile or LCR-B liner can be turned by using the locked air push rods for proper alignment with the branch.
Handling is easy
After cure, a vacuum pump integrated into the LCR-B control box removes all air from the LCR-B packer, which then can be removed.
- Practical: Only little equipment is needed to execute repairs successfully
- Low cost: Just buy the packers actually required - investment is small
- Handy: The low-weight mobile unit requires little space only and can be placed even in a small car
- Flexible: LCR-B packers can be folded if required
- Save: The resin systems used are easy to impregnate, they contain no styrene.
- Time saving: 50% less operating time due to steam curing
