Description

MarMac MacWrap is a highly-advanced, external joint coupler designed to permanently prevent infiltration at precast concrete structure connections, including reinforced concrete pipe (RCP), manhole sections, box culverts & stormwater retention systems, and many other round or elliptical concrete structures.

External seals for reinforced concrete pipe joints

MacWrap for RCP (Reinforced Concrete Pipe) is a high performance, external joint coupler designed for the prevention of infiltration and resistance of exfiltration at joints of bell-and-spigot, tongue-and-groove, round, or elliptical RCP.

MacWrap’s specially formulated mastic is designed to aggressively adhere to the exterior concrete pipe surface, with the tightened mechanical straps creating a nearly indestructible seal. MacWrap for RCP  is permanent, immediately inspectable, and boasts a 100% success rate. Simply put, MarMac MacWrap is the best there is.

MacWrap Couplers integrate several unique components into a single, customizable, full-perimeter, external sealing band. Our specially-formulated mastic provides a positive seal against infiltration. The coupling membrane is reinforced by internalized woven polypropylene with a heavy duty polyethylene backing and secured by high-tensile compression bands with tensioning ratchets.

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.
