SBS Details

1 WORK INCLUDED

(1) Base sheet membrane flashing: Waterproofs the expansion joint structure and provides a base layer for the control joint to bond material to bond with.
(2) Expansion joint (elastomeric product illustrated): This joint is proprietary to its manufacturer and will be fitted, manufactured, and installed, or supervised, by others. Secure to substrate as required by manufacturer.
(3) Reinforced membrane strip: Applied to cover the control joint and seal it to the base membrane system.
(4) Cap sheet membrane flashing: Installed as required in Part 10 and applied as the second or third of a two or three-ply membrane system, providing required coverage above the finished roof system surface. Smooth membrane is shown on parapet coping (may be granule-surfaced, depending on material specified).
(5) Metal cap (coping) flashing: Fabricated and installed as required in Part 13.
(6) Metal counter-flashing: The counter-flashing below the cap flashing is secured independently of the metal cap flashing to permit movement of the expansion joint assembly across the planes of anticipated structural movement. Dimensions are project-specific.
