3、rially corrected in May 2017.1. Scope1.1 This practice describes the procedures for the rehabili-tation of sewer lines and conduits by the installation of afield-fabricated PVC liner. After installation of the liner,cementitious grout is injected into the annular space betweenthe liner and the exist
4、ing sewer or conduit.The rehabilitation ofthe host structure by this installation practice results in a rigidcomposite structure (PVC/grout/existing pipe). This rehabilita-tion process may be used in a variety of gravity applications,such as sanitary sewers, storm sewers and process piping ofman-ent
5、ry sizes (36 to 144 in. in vertical dimension). Theprofile strips used for field fabrication of PVC liners aresupplied in coils for spiral winding of the liner or in custom-cutflat panels for circumferential lining of all or any portion of thecircumference of the host conduit (see Figs. 1 and 2).1.2
