摘要：
The repair of a sewer line having a fracture, and employing a liner sleeve and an elastomer sleeve extending about the line sleeve, and a filler slurry, includes:(a) installing the liner sleeve and the elastomer sleeve endwise in the sewer line to locate the two sleeves in bridging relation with the fracture, and(b) displacing slurry into a space formed between the two sleeves to cause the elastomeric sleeve to expand and seal against the sewer line in bridging relation with the fracture.
