1.1 The practice describes the procedures for the rehabilitation of sanitary and storm sewer pipes, culverts, tunnels, and conduits by the installation of a field-fabricated polyvinyl chloride (PVC) liner system. After installation of the liner system, cementitious grout is pumped into the annular space between the liner and the host structure. The rehabilitation of the host structure by this installation practice results in a rigid composite structure (PVC liner/grout/existing pipe). This type of rehabilitation process is suitable for a variety of gravity pipe applications such as storm sewers, sanitary sewers, and culverts and with geometries including circular, egg, ovoid, elliptical, arch, and site-specific composite shapes. 1.2 Units--The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the 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.
This standard is needed to document the correct installation of the materials being developed in WK33083.
