Introduction
The unique "no-dig" system, that needs no access point in the lateral pipe. TheTrelleborg Main-to-House (MtH) System is a method for the trenchless rehabilitation of property drainage lines by means of the cured-in-place pipe (CIPP) lining technology. The difference from the usual method is the lining direction: It works from the main pipe to sustainably renovate lateral connection pipes!
MtH - making it different
Conventional CIPP Lining methods are applicated either in the main sewer, working from manhole to manhole, or in house service lines that lead to the main pipe. In both cases two access points are required, one as start point to bring in the devices for the lining process, the other as landing point where the installation ends and final steps are taken to complete the installation.

MtH - a sustainable solution
The MtH method also provides a solution for the main/lateral interface. The crucial advantage is the homogeneous integration of the lateral liner with the stabilizing „main pipe liner“ in the mainline. The main/lateral interface liner adheres to the main pipe without annular space and thus provides a perfect seal also for improperly connected laterals.

Application Areas
Suitable for the renovation of sewer pipes made of concrete, steel, reinforced concrete, clay, fibro cement, GRP, PVC, PE, PP, and cast iron, if the cross-section of the host sewer meets the process requirements and the structural stability criteria.
Training on theory and practice
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.
