The repair of joints and laterals in house connection or building pipes with the LCR method is done with the aid of specific carrier materials which seal the junction area of the lateral connection on the main pipe, and a defined length into the side connection at the same time. If a "hat profile" is used, it seals the connection of the two pipe systems in the main pipe with its brim. If the lateral connection area in the main pipe is to be rehabilitated more comprehensively and sustainably, an appropriately designed "LCR liner" is used.
LCR liners are hose liners adapted to the diameter and length of the lateral connection to be rehabilitated with an integrated "main liner" at the end which is designed multi-dimensionally in the form of two open layers. In this way, several pipe diameters can be covered at the same time - as with the packer types.
The high-quality material of the LCR hat profiles and LCR liners consists of a mixture of 85% glass fibre and 15% polyester fibre.
