Conforming to ASTM standards, the SS40 joint system consists of a shallow “v” profile elastomeric membrane mechanically and chemically interlocked into steel locking edge rails. Providing a rated movement of up to 4″, the SS40 is an industry standard design that can be modified to accommodate roadway skews, turn-ups, and laybacks. Key features include: Parapet to parapet continuous membrane Membrane convulutions transfer minimal stress across the expansion joint at all movement ratings. Water-tight seal Shop fabricated parapet, sidewalk, and roadway cover plates, when required. Elastomeric Compression Seals: Extruded compression seals provide a water tight seal at joint openings for concrete pavements. Designed with an open web design, elastomeric compression seals apply a constant and uniform compression for the entire range of joint movement. Non-Preformed Fabric Reinforced Membranes: Commonly utilized under steel hold down panels, non-preformed fabric reinforced membranes are used to provide 0″ to 4″ of total movement. The joint membranes are bolted between steel hold down panels and sealed with a lubricant adhesive to ensure a water-tight seal. The rubber sheeting is reinforced with a one-ply or 2-ply non-wicking woven nylon or polyester fabric. The membrane is typically fabricated from 1/8″ to 1/4″ thick material and can be shop fabricated for longitudinal and and transverse joint layouts. Custom Expansion Joint Systems: We offer innovative solutions for other expansion joint systems including custom steel armor and plate fabrication, pedestrian bridge cover plates, slip-resistant cover plates, sidewalk cover plates, parapet and median cover plates.
