In common with most single ply material, EPDM will over time try and shrink by up to 10% back to the centre. The base tie-in controls the membrane movement and stops the membrane pulling away where the membrane turns up through an angle change. The rest of the movement is accommodated by the FIX-R Membrane and its ability to elongate by over 300%. FIX-R PS RUSS Strip (Reinforced Universal Secure Strip) is used to mechanically secure EPDM Membranes to the substrate. The strip has tape pre-applied along one edge and can be installed horizontally or vertically in conjunction with Seam Fastening Plates below the EPDM Membrane for additional membrane securement. Pressure Sensitive Reinforced Universal Securement Strip is a reinforced EPDM membrane 152mm wide with a 76mm wide adhesive strip. PS RUSS has the splice tape pre-applied along one edge, and can be installed horizontally or vertically in conjunction with Seam Fastening Plates below the EPDM deck membrane for additional membrane securement.
