SPECIFICATION Sections 07 90 00 / 07 95 00 THERMAFLEX by EMSEAL Watertight Traffic Bearing Deck Expansion Joint Membrane/Nosing System ***Note to Specifier: THERMAFLEX is available in two models: TM and TCR. TM utilizes a double-cell gland and TCR utilizes a multi-cell gland. Please consult THERMAFLEX tech data sheets or contact EMSEAL tech assistance at 800-526-8365 to determine the best configuration for the project.PART 1 – GENERAL
Standard Submittal Package – Submit
typical expansion joint drawings(s) indicating pertinent
dimensions, general construction, expansion joint
opening dimensions and product information.
Sample of material is required at time
of submittal. Product Delivery, Storage and Handling Deliver products to site in
Manufacturer’s original, intact, labeled containers.
Handle and protect as necessary to prevent damage or
deterioration during shipment, handling and storage.
Store in accordance with manufacturer’s installation
instructions. Basis of Design All joints shall be designed to meet the
specified performance criteria of the project as
manufactured by: (USA & International) EMSEAL JOINT
SYSTEMS, LTD 25 Bridle Lane, Westborough, MA 01581-2603,
Toll Free: 800-526-8365. (Canada) EMSEAL, LLC 120
Carrier Drive, Toronto, Ontario, Canada M9W 5R1 Toll
Free: 800-526-8365. www.emseal.com
Alternate manufacturers must demonstrate
that their products meet or exceed the design criteria.
Submittal of alternates must be made three weeks prior
to bid opening to allow proper evaluation time. Quality Assurance The General Contractor will conduct a
pre-construction meeting with all parties and trades
involved in the treatment of work at and around
expansion joints including, but not limited to,
concrete, mechanical, electrical, HVAC, landscaping,
masonry, curtain wall, waterproofing, fire-stopping,
caulking, flooring and other finish trade
subcontractors. All superintendents and foremen with
responsibility for oversight and setting of the joint
gap must attend this meeting. The General Contractor is
responsible to coordinate and schedule all trades and
ensure that all subcontractors understand their
responsibilities in relation to expansion joints and
that their work cannot impede anticipated structural
movement at the expansion joints, or compromise the
achievement of watertighness or life safety at expansion
joints in any way.
The General Contractor shall provide a
field report that summarizes the project conditions and
any remedial action necessary to correct field
conditions (substrate, joint size, blockout, vertical
offsets, etc.) that may affect expansion joint system
performance.
Warranty – Manufacturer’s standard
warranty shall apply. PART 2 – PRODUCT General Provide traffic durable, watertight,
expansion joint by EMSEAL JOINT SYSTEMS for expansion
joints and isolation joints in decks. Typical
locations include, but are not limited to the following:
applications for joints over occupied space, parking
deck joints, stair tower perimeters, elevator
perimeters, stadium tread and risers, stadium
concourses, and solid slab structural expansion joints.
System shall perform waterproofing, traffic bearing and
movement-accommodation functions.
Provide THERMAFLEX TM or TCR as
manufactured by EMSEAL JOINT SYSTEMS LTD and as
indicated on drawings for horizontal expansion joint
locations.
Expansion joint system shall be
comprised of: 1.) a heat-weldable, santoprene,
thermoplastic-rubber, double-celled or multi-celled,
extrusion with perforated flanges and, 2.)
manufacturer’s cold applied elastomeric nosing.
Elastomeric nosing 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 exceed 1:2.
System to be installed into blockouts on
each side of the joint-gap prepared to the dimensions of
¾" deep x 3" wide (20mm deep x 75 mm wide) for TM and ¾"
deep x 3 1/2" wide ( 20mm deep x 90mm wide) for TCR.
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.
Manufacturer’s Checklist must be
completed by expansion joint subcontractor and returned
to manufacturer at time of ordering material. Fabrication Directional changes and terminations
into vertical plane surfaces (walls, parapets, ends of
decks, etc) as well as to transition the material
through curbs, treads and risers or other in-slab plane
changes to be provided by factory-manufactured
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. PART 3 – EXECUTION Installation Preparation of the Work Area The contractor shall provide
properly formed and prepared expansion joint
openings constructed to the exact dimensions and
elevations shown on manufacturer’s standard system
drawings or as shown on the contract drawings.
Deviations from these dimensions will not be allowed
without the written consent of the engineer of
record.
The contractor shall clean the joint
opening of all contaminants immediately prior to
installation of expansion joint system. Repair
spalled, irregular or unsound joint surfaces using
accepted industry practices for repair of the
substrates in question. Remove protruding roughness
to ensure joint sides are smooth. Refer to
Manufacturers Installation Guide for detailed
step-by-step instructions.
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. Bids must include
for presence of paid-for manufacturer’s field
technician to be present during initial preparation,
inspection, and material installation. Clean and Protect Protect the system and its components
during construction. Subsequent damage to the expansion
joint system will be repaired at the general
contractor’s expense. After work is complete, clean
exposed surfaces with a suitable cleaner that will not
harm or attack the finish. END OF SECTION |
