[origin: US5778937A] PCT No. PCT/AT95/00040 Sec. 371 Date Aug. 29, 1996 Sec. 102(e) Date Aug. 29, 1996 PCT Filed Mar. 1, 1995 PCT Pub. No. WO95/23940 PCT Pub. Date Sep. 8, 1995A method for producing leak-proof sites of entry for domestic connection pipes and other feed pipes into sewers. The method includes the steps of widening the site of entry of the feed pipe into the sewer, providing a barrier towards the interior of the sewer at the site of entry, providing a barrier within the feed pipe at a predetermined distance from the site of entry, introducing an expanding solidifying sealing mass into the space between the barriers so as to fill the space and any openings, fissures, or cracks found therein, clearing a path of flow from the feed pipe through the sealing mass and into the sewer, and optionally lining the flow path with a solidifying, insoluble, corrosion-resistant and non-ageing material.
