    MacWrap Repair Coupler is an advanced, external joint coupler, specifically designed to repair compromised joints of precast structures while simultaneously preventing infiltration. MacWrap Repair couplings can be used for the rehabilitation of tongue & groove and bell & spigot reinforced concrete pipe as well as manhole sections, restoring the integrity of damaged joints.

    With its membrane comprised of the same materials as a standard MacWrap, the width of MacWrap Repair Couplers is increased to 24”, four compression bands are utilized versus the standard two, and the thickness is increased by approximately 50%. This is a heavy-duty, 3-ply coupler as the membrane contains an additional layer of polyethylene and mastic.

    SPECIFICATION

    MacWrap integrates several unique components into a single, full-perimeter, external sealing band. The coupler composition consists of:

    • Heavy duty polyethylene backing
    • Internal woven polypropylene reinforcement
    • High-tensile compression bands
    • Specially formulated mastic contact layer

    INSTALLATION

    Surface preparations: Inspect the outside of the joint. Brush and/or repair surface as needed to ensure there are no loose materials or voids. If installing on horizontal pipe, dig the bell hole for complete access to the joint.

    The coupler shall be placed around the pipe, mastic side centered on the pipe joint, and then the protective release film shall be removed. The straps will then be tensioned and secured with preinstalled ratchet tensioners. The closing flap shall cover the service area and exposed straps, completing the installation. Backfill may commence immediately following the inspection of proper sealing band installation.
