This work consists of the method and process for furnishing all labor, materials, tools, equipment, and incidentals, necessary to provide for point repairs and complete rehabilitation of sanitary sewer pipes by Grouting or forming a new tight-fitting liner within the existing pipe. Work will be done and paid on an as needed basis. The process in a typical and general form consists of a flexible felt tube impregnated with an approved resin, which is inserted into an existing pipe. The curing may be accomplished by circulating heated water, curing resin system to affect the desired cure throughout the length of the tube, extending full-length from structure to structure. The resin should be cured into a hard, impermeable pipe of the desired thickness, providing a structurally sound, smooth interior and tight-fitting liner within the existing pipe. The lined pipe shall provide a hydraulic flow equal to, or greater than, the original new sewer capacity.
