MacWrap External Collar High-Strength Inflow and Infiltration barrier For over 30 years, MacWrap has been installed on thousands of pipe joints annually, providing a positive, permanent seal against Infiltration.
MacWrap is a custom-fit, full perimeter seal that meets or exceeds ASTM C-877 (Type II) standard and passes the ASTM C-1244 vacuum test. For more information on ASTM standards, click here...
MacWrap can be installed on round, elliptical and arch pipe; box culverts; tongue and groove joints; bell and spigot joints.
MacWrap incorporates high-strength, shear and puncture resistant internal polypropylene mesh with an impervious, chemical resistant polyethylene outer cover for optimal performance. The self-adhering rubberized mastic element of MacWrap is formulated to flow into the wall surface of the concrete and create a permanent bond. Additionally, two 5/8 inch compression bands are incorporated inside the collar to provide added assurance for a positive seal on each side of the joint.
