Patent ID: 7270150

Claim:
A method for installing a liner in an underground pipeline, having an interior and exterior surface and service laterals extending thereform, comprising the steps of: applying a first resin to the interior surface of the pipeline, said first resin including a pigment agent mixed therein; placing a lining hose in a collapsed state into the pipeline, said lining having an outer layer and inner layer, wherein the inner layer includes a second resin, said second resin being non-opaque; placing a calibration hose into the lining hose; introducing pressurized fluid into the calibration hose; expanding the calibration hose using a pressurized fluid, said calibration hose expanding against the inner layer of the lining hose causing said lining hose to contact said second resin; pressing the lining hose against the interior surface of the pipeline with the first resin residing therebetween to cure said first and second resins so that the lining hose bonds to the interior surface of the pipeline; removing the calibration hose from the lining hose; and removing regions of said lining hose adjacent said service laterals using a remote cutting device by visually identifying and clearing said service lateral locations.
