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
and must submit certified performance test reports
performed by nationally recognized independent
laboratories as called for in section 1.02 Submittals.
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.
Warranty – Manufacturer’s standard
warranty shall apply.
LEED Building Performance Requirements:
The VOC of the silicone must not exceed 50 grams/liter. PART 2 – PRODUCT General Provide traffic durable, watertight,
sound dampened, 1 or 2 hour fire rated, seismic,
large-gap, and high-movement expansion joint by EMSEAL
JOINT SYSTEMS. Typical locations include, but are not
limited to the following applications for joints over
occupied space, stadiums, floors, and parking deck
joints. System shall perform waterproofing, traffic
bearing and movement-accommodation functions as the
result of a single installation and without the addition
of gutters, vapor barriers, bladders, or other devices
suspended beneath or within the system in any way.
Provide EMSHIELD SJS-FR1 / EMSHIELD
SJS-FR2 as manufactured by EMSEAL JOINT SYSTEMS LTD and
as indicated on drawings for horizontal expansion joint
locations.
System shall be comprised of the
following components: 1.) fire-retardant-impregnated
foam pre-coated on the underside with an intumescent
fire-proofing material, 2.) pre-coated with a watertight
silicone outer coating, 3.) heavy-duty extruded
aluminum/polycarbonate center spline, 4.) interlocking
spline connectors and heavy duty cover plates, 5.)
field-applied epoxy adhesive primer, 6.) field-injected
silicone sealant bands.
Material shall be capable of movements
of +50%, -50% (100% total) of nominal material size.
Standard sizes from 4" (100 mm) to 10" (250 mm). Depth
of seal is 6" (150mm).
Silicone coating to be highway-grade,
low-modulus, jet-fuel resistant silicone factory-applied
to the foam while it is partially pre-compressed to a
width greater than maximum joint extension and cured
before final compression. When compressed to final
supplied dimension, a bellow(s) to handle movement must
be created in the silicone coating. EMSHIELD SJS-FR1 / EMSHIELD SJS-FR2 to
be installed directly over a leveling-bed of elastomeric
nosing material to be supplied by manufacturer.
Elastomeric nosing material to have an aggregate of
fine, washed sand not to exceed 30 mesh and chopped
strand fiberglass AND aggregate to resin ratio not to
exceed 2:1 by weight.
EMSHIELD SJS-FR1 / EMSHIELD SJS-FR2 to
be installed into manufacturer’s standard field-applied
epoxy adhesive.
EMSHIELD SJS-FR1 / EMSHIELD SJS-FR2 is
to be installed slightly recessed from the surface such
that when the field-applied injection band of silicone
is installed between the substrates and the
foam-and-silicone-bellows, the system will be
essentially flush with the substrate surface.
Tool-steel, connector pins shall be
located in center spline for end to end connections.
Heavy duty cover plate to be held in place by
stainless-steel, self-tapping screws installed into the
continuous anchor channel of the heavy-duty extruded
spline. No mechanical self-centering bars, springs, or
sliding ball components shall be employed in maintaining
coverplate attachment and centering.
Select the system model appropriate to
the movement and design requirements at each joint
location that meet the project specification or as
defined by the structural engineer of record.
Manufacturer’s Checklist must be
completed by expansion joint subcontractor and returned
to manufacturer at time of ordering material. Fabrication EMSHIELD SJS-FR1 / EMSHIELD SJS-FR2 by
EMSEAL must be supplied precompressed to less than the
joint size, packaged in shrink-wrapped lengths (sticks).
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 single
units or through field fabrication in strict accordance
with published installation instructions. 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. Ensure that there
is sufficient depth to receive the full depth of the
size of the EMSHIELD SJS-FR1 / EMSHIELD SJS-FR2
being installed. Refer to Manufacturers Installation
Guide for detailed step-by-step instructions.
No drilling, or screwing, or
fasteners of any type are permitted to anchor the
system into the substrate.
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 END OF SECTION |
