RFB-RD 14-14 - STORMWATER PIPE REHABILITATION CURED-IN-PLACE PIPE

Summary of Specifications:
The intent of this specification is to provide a recommended set of guidelines for the reconstruction of pipelines and conduits through the use of cured-in-place pipe (CIPP). In this specification recommended references, prequalification requirements, materials, pre- and post installation inspection tests have been provided. The process generally consists of inserting a resin impregnated fabric tube into an existing pipe or conduit, expanding the tube against the existing pipe, and curing the tube to form a pipe within a pipe. The tube may be inserted into the pipe by direct inversion or pulling in place. Curing is accomplished by either circulating heated water or steam or ambient temperature air or water to affect the desired cure throughout the pipe from access point to access point.
