| 20080223469 | MULTIPLE CONDUIT-REPAIR METHOD - A method for repairing multiple conduits using a vacuum collapsed, elastic liner involves providing a quantity sufficient for multiple repairs to the work sight and inserting a length into the damaged conduit. The protruding liner is then heat-sealed to prevent volume flow between the inserted liner and the remaining liner. The inserted liner vacuum is broken enabling the inserted liner to reassume its original size and shape. In doing so the expanded liner seals the problematic breeches. A retaining sleeve is then inserted in the expanded liner to hold it in place. | 09-18-2008 |

| 20100012214 | Pipe lining material and method for manufacturing same - A pipe lining material comprising an inner lining material and an outer lining material is used to rehabilitate an aged existing pipe. The inner lining material and the outer lining material are made of a tubular resin-absorbent material that is impregnated with a photo-curing resin and a thermosetting resin. The resin-absorbent material of the inner lining material has a higher density than that of the outer lining material. The photo-curing resin of the inner and outer lining materials is cured by light when the pipe lining material is irradiated with light, and the heat generated when the photo-curing resin is cured cures the thermosetting resin of the inner and outer lining materials. Since the resin-absorbent material of the inner lining material has a high density, voids are less readily formed. Even if voids are generated in the resin-absorbent material of the outer lining material, the voids will be covered by the inner lining material having fewer voids. This ensures that the pipe lining material will have better water-tightness. | 01-21-2010 |
