The method
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 repair 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 - changing the direction
Trelleborg’s trenchless operating Main-to-House pipe rehabilitation system makes, in the truest sense of the word, the change in direction. This new system works from the main pipe to repair lateral connection pipes. In addition there is no need to make an access pit or hole inside or outside the building. This requires no direct contact or interference with the property owner.
The new MtH method is also the perfect solution when there is no second access point at all, e.g. due to constructional reasons.
MtH - being 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 main line. The main/lateral interface liner adheres to the main pipe without annular space and thus provides a perfect seal also for improperly connected laterals.
