The membrane is bonded onto the leak control flange and terminated horizontally, or horizontally and vertically. The flange is recessed into the substrate without protruding, sealed to the riser, fixed so it cannot move, of the same nominal diameter as the riser, and finished with a fillet of sealant where it meets the substrate. With a shower tray, the tile bed must be able to drain and the drain connection must be waterproof. The flange must not sit where it interferes with bond breakers or wall to floor junctions.
