SPECIFICATION Sections 07 90 00 / 07 95 00 HORIZONTAL COLORSEAL by EMSEAL Preformed, Pre-Compressed, Self-Expanding, Sealant System with Silicone Pre-Coated Surface Watertight, Non-Traffic, High Movement, Primary Seal for Horizontal Joints PART 1 – GENERAL
Standard Submittal Package – Submit typical expansion
joint drawing(s) indicating pertinent dimensions, general construction,
expansion joint opening dimensions and product information.
Sample of material is required at time of submittal.
All products must be certified by independent
laboratory test report to be free in composition of any waxes or wax
compounds using FTIR and DSC testing.
All products shall be certified in writing to be: a)
capable of withstanding 150°F (65°C) for 3 hours while compressed down
to the minimum of movement capability dimension of the basis of design
product (-50% of nominal material size) without evidence of any bleeding
of impregnation medium from the material; and b) that the same material
after the heat stability test and after first being cooled to room
temperature will subsequently self-expand to the maximum of movement
capability dimension of the basis-of-design product (+50% of nominal
material size) within 24 hours at room temperature 68°F (20°C). 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.

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:
PART 2 – PRODUCT
Provide HORIZONTAL COLORSEAL as manufactured by EMSEAL
JOINT SYSTEMS LTD and as indicated on drawings for horizontal expansion
joint locations.
Preformed sealant shall be silicone pre-coated,
preformed, pre-compressed, self-expanding, sealant system. Expanding
foam to be cellular foam impregnated with a water-based, non-drying,
100% acrylic dispersion. Seal shall combine factory-applied, low-modulus
silicone and a backing of acrylic-impregnated expanding foam into a
unified hybrid sealant system.
Material shall be capable of movements of +50%, -50%
(100% total) of nominal material size.
Silicone external color facing to be 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. Silicone coating to be
available in a range of not less than 26 standard colors for
coordination with typical building materials.
HORIZONTAL COLORSEAL to be installed into
manufacturer’s standard field-applied epoxy adhesive.
HORIZONTAL COLORSEAL 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.
Select the sealant 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 HORIZONTAL COLORSEAL by EMSEAL must be supplied
precompressed to less than the joint size, packaged in shrink-wrapped
lengths (sticks).
Directional changes and terminations into horizontal
plane surfaces to be provided by factory-manufactured
universal-90-degree single units containing minimum 12-inch long leg and
6-inch long leg or custom leg on each side of the direction change 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 HORIZONTAL COLORSEAL 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 sealant system into the substrate. 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 |
