1.1 This practice describes the procedures for the rehabilitation of sewer lines and conduits by the installation of a field-fabricated PVC liner. After installation of the liner, cementitious grout is injected into the annular space between the liner and the existing sewer or conduit. The rehabilitation of the host structure by this installation practice results in a rigid composite structure (PVC/grout/existing pipe). This rehabilitation process may be used in a variety of gravity applications, such as sanitary sewers, storm sewers and process piping of man-entry sizes (36 to 144 in. in vertical dimension). The profile strips used for field fabrication of PVC liners are supplied in coils for spiral winding of the liner or in custom-cut flat panels for circumferential lining of all or any portion of the circumference of the host conduit (see Figs. 1 and 2).
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Particular attention is drawn to those safety regulations and requirements involving entering into and working in confined spaces.
