The Trelleborg LCR-B method
Vertical and horizontal house pipe repairs without breaking walls
Leaking down-pipes 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 of walls and/or grounds – then make people suffer noise, dirt and service disruption. Trelleborg Pipe Seals have a remedy for this problem: The Trelleborg LCR-B repair method repairs laterals without breaking out walls or excavations, and thus means much less annoyance of residents.
How the Trelleborg LCR-B works
The Trelleborg LCR-B is a pipe repair device or method for the rehabilitation of 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 by means of compressed-air push rods.
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 mouth piece of the LCR-B hat profile or LCR-B liner can be turned by means of the locked air push rods for proper alignment with the branch.
Easy to handle
The LCR-B packer will be inflated to start the inversion process of the LCR hat profile. After complete inversion the pressure will be maintained until final cure.
After cure, a vacuum pump integrated in the LCR-B control box removes all air from the LCR-B packer which then can be removed.
Reliable results
The LCR-B hat profile in the main pipe seals the interface between the two pipe systems with its rim only, whereas the LCR-B liner is designed as a short liner in the down pipe or house sewer.
The standard lateral repair length is 300 mm - the new LCR-B packer model allows a maximum repair length of 1300 mm.
The Advantages at a glance
-
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 low space only and can be placed even in a small car
-
Flexible: LCR-B packers can be folded as required
-
Save: The resin systems used are easy to impregnate, they contain no styrene, VOC's etc. and in case of fire are self-extinguishing.
-
Time saving: 50% less operating time due to steam curing

- Displaced pipes, cracks and debris, ruptures
- Mechanical wear
- Corrosion
Inapplicable Damages
- extreme pipe or joint offsets

- large cross-sectional reductions in conjunction with bedding problems
- longitudinal cracks at pipe connections
Before and after curing
before
Leaking lateral pipe
Water Infiltration through leaking joints
after
Repaired lateral pipe
The infiltration is stopped, the pipe is watertight.
Leaking and damaged pipes affect the stability of structural systems.
About a third of the most sewer systems is older than 75 years
The average life span of pipes and sewers counts 80 years.
Defects and cracks in the pipes lead to significant pollution of the groundwater
More then 40% of private property drainage pipes are estimated to be defect
Drugs, sweeteners and hormones can only be partially biodegraded.

Trelleborg LCR-B Bladder
Packers are available in different sizes: S and L for lateral rehabilitation lengths of 280 mm/11 inch and 1180 mm/46.5 inch respectively. They can easily be converted into the dimension that is needed for the lateral connection (DN 50 - DN 200).
Usable for both, hot water or steam cure.
Trelleborg LCR-B Hat Profile 300 / 1200 mm
The LCR-B liner and hat profile material is suitable for steam curing and has high mechanical properties and very good sealing capabilities.
As an alternative to the specifically developed hat profile, it is also possible to use a liner of the appropriate size.
Standard rehabilitation length is 300 mm / 1200 mm is available on demand.
LCR Hat profiles and LCR-Liner are made of 80% ECR Fibre Glass and 15% Polyester Fibre. The surface is covered with a PVC foil, the rim is reinforced.

Trelleborg LCR-B Control Box
The LCR-B control box controls the compressed air and the vacuum for the LCR-B packer.
Trelleborg LCR-B Push Rod
Push rods are available in different materials and lengths (0.7 m; 1.5 m; 3.0 m)
LCR-B air push rods are equipped with safety coupler and lock.
Trelleborg LCR-B Steam Gen 3/6
Trelleborg Pipe Seals highly recommends steam curing for Trelleborg LCR methods.
This small steam unit is the best solution if you want to speed up the curing time of built-in hat profiles
or LCR liner, using the Trelleborg LCR method for lateral connection repair of underground house
sewers and down-pipes in buildings. It is easy to handle and suited for portable use.
