Bonding pad for nonpenetrating roof membrane fastening system

摘要

A bonding pad for securing a waterproof membrane to a roof deck without requiring any penetration of the membrane. The pad has a base member of EPDM with a thin bottom coating of a nonwoven polyester fabric. An EPDM tape having adhesive on both sides is secured to the top surface of the base member. A rigid attachment plate and fastener secure the base member and EPDM tape to the roof deck with the top layer of adhesive securing the membrane to the pad. Preferably the EPDM tape comprises two separated strips forming an air flow channel therebetween with the attachment plate being located with the channel. A primer coat is applied to the top layer of adhesive on the EPDM tape after an adhesive release paper is removed prior to securing the membrane to the bonding pad.
