Root Barrier for Drainage Pipes - MarMax Tape - MarMac Manufacturing Company

The MicroSealant® technology utilized by MarMax™ is extremely stable and resistant to oxygen, ozone, and heat. MarMax™ is formulated from synthetic polymers and contain a built-in primer that facilitates instant bonding to most known materials used in transportation, roofing, and the traditional building envelope, such as: EPDM rubber, TPO, hypalon, aluminum, galvanized steel, steel, wood, fiberglass, and much more. It will not adhere to silicone. Easy to use, MarMax™ is a permanent fix for leaks and other weather-proofing repairs.

MarMax™ has an extremely wide temperature tolerance, remaining flexible in temperatures as low as -70°F (-57°C), making it virtually impossible to thermally shock the seam causing a leak. MicroSealant® technology makes MarMax™ a self-healing tape and extremely robust to a wide range of surface conditions, resulting in reduced steps during installation.

*MarMax™ is not compatible with silicone sealants or lubricants. Avoid using silicone based products near MarMax™.
