The epros®DrainLCR-S system is an essential method and a tool to repair and permanently seal main/lateral interfaces and connections up to 600 mm from the main line down into the lateral. The system can use either an LCR-S hat profile or an LCR-S liner.
The main-to-lateral interface in the main pipe is sealed only by the rim of the LCR-S hat profile, while the LCR-S liner in the main pipe is designed as a short liner. In both cases, the forming element is an inflatable pro-formed hose that serves the same function. This inflatable hose in the form of a cylinder (packer hose), is additionally equipped with another cylinder located at the mid-point (the lateral hose) at an angle of 45° or 90° to the axis of the packer. The LCR-S packer method allows to repair lateral connections with bends from 30° to 90°.
