The ChemCurb System replaces the old style metal pitch pans with versatile precast curb components, 1-Part polyether pourable sealant, and structural adhesive/sealant. The system can usually be installed in under 15 minutes and eliminates the need for flashing or mechanical attachment. The ChemCurb System is designed for use on granulated modified bitumen, PVC, EPDM, PIB, TPO single ply, asphalt, and coal tar B.U.R. Please note TPO Primer must be used on TPO single-ply roof substrates. When installed properly, the ChemCurb System forms a durable waterproof rubber seal around penetrations of any size.

The Pro Pack® ChemCurb Kits include bisected circular pieces with inside diameter of 5 or 7.5 inches, M-1 Universal Adhesive & Sealant, Pro Pack resin and hardener, a mixing paddle and warranty card.
