The ChemCurb system from ChemLink is a tough, 2-inch deep poured rubber waterproofing seal that installs in under five minutes. A pre-cast polyester composite or black structural urethane curb is bonded to the roof surface, creating a form for the rubber seal and protecting it from ice or mechanical damage. The system’s M-1 bonding adhesive elongates 300 percent and has a shear strength of 300 pounds per square inch on metal, masonry and wood. The 1-Part pourable sealer is self-leveling and moisture-cured. It works with EPDM, PVC, BUR, coal tar, SBS mod bit, granulated APP and many types of coated metal roofing.
