Basis of Design: THERMAFLEX TCR by EMSEAL for watertight traffic bearing deck expansion joints for applications including but not limited to, parking decks, stadium and sports facility tread and riser joints, stadium and sports facility concourse joints in solid slabs, and structural expansion joints.
Expansion joint system shall be comprised of a heat-weldable, Santoprene, thermoplastic-rubber, double-celled extrusion with perforated flanges embedded in a cold applied elastomeric nosing which shall be a two-part polyurethane material (epoxies not permitted) mixed with aggregate with sand particles not to exceed 30-mesh. Nosing material shall be pourable grade material capable of encapsulating the perforated flanges in a single pour without the laying of a setting-bed or tack coat. The material shall flow so as to fill voids or irregularities in concrete blockouts and beneath the perforated flanges of the gland. Material shall cure to flexible (non-rigid) state. So as to ensure proper mixing, flow ability, and consolidation, mixed nosing material shall have an aggregate loading ratio by weight of liquid resin to aggregate not exceeding 1:2.
Physical properties of sealing gland and nosing material to be in accordance with manufacturer’s current published data.
Final selection of the seal size to be coordinated between manufacturer, designer, and contractor(s) in consideration of expected movements as a product of structural design and expected temperature variations, taking into account as-built joint-gap sizes and temperatures at expected installation time. Width of joint-gaps at time of casting or cutting to be adjusted, if necessary, from baseline temperature used and specified by designer in determining system suitability.
System to be installed into blockouts on each side of the joint-gap prepared to the dimensions of 20mm deep x 75mm wide (3/4″ deep x 3″ wide) on each side of the joint-gap. System to be installed by qualified sub-contractors only according to detailed published installation procedures and/or in accordance with job-specific installation instructions of manufacturer’s field technician.
All terminations at ends of joints as well as all changes in plane and direction to be executed using factory-fabricated assemblies that preserve continuity of seal. Transitions between THERMAFLEX and any other of Manufacturer’s joint systems in the vertical plane to be executed according to Manufacturer’s details and to be warranted as watertight.
