Part 2. Products 2.01 ACCEPTABLE MANUFACTURER A. Rubber Isolation Mat: Wilrep Ltd., 1515 Matheson Blvd. East, Unit C-10, Mississauga, Ontario L4W 2P5. Tel: ; Toll Free ; info@wilrep.com; Web: and B. Substitutions: Not permitted, however requests for substitutions will be considered providing substitute products and methods of execution are submitted at least 10 days prior to bid closing date.

4 C. Accompany requests with evidence substantiating similarity in quality, including technical data sheet and formal 3-Part specifications MATERIALS SPEC NOTE: Delete items not required. A. Rubber Isolation Mat: Iso-Sep 25HD High Dimple specially designed, oneside dimpled, heavy duty recycled polyurethane rubber isolation mat, black coloured, roll size 1220 mm (48 ) wide x 4.6 m (15-0 ) long x 25 mm (1 ) thickness. B. Perimeter Isolation Strips: Same as rubber isolation mat as above, 25 mm (1 ) thickness. C. Penetrations Isolation Board: Closed cell polyethylene 6 mm (1/4 ) and 10 mm (3/8 ) thickness x height to suit overall thickness of floating floor. SPEC NOTE: Specify perimeter caulking only if required by building code. D. Perimeter Caulking Compound: Non-hardening, non-drying, non-bleeding, trowel or pour grade, Type. E. Polyethylene Sheeting: Minimum 6 mil thickness. F. Floating Floor Drains: Aluminum or cast iron design. Upper funnel section cast into the floating floor. Lower funnel, built into the structure, to have drainage holes for draining the lower floor. To be fabricated with between floors sound seal and appropriate clamping devices. Drain manufacturer:[ ] DESIGN CRITERIA A. Provide acoustical isolation to prevent transmission of sound and vibration generated by [mechanical and electrical equipment] [or] [ ] to adjacent building areas. This requirement includes isolation of all items passing through the floating floor. B. Acoustically isolated floor to provide predictable system actual frequency as stated in manufacturer s literature. C. Normal design load calculations for rubber isolation mat and layout to be based on the weight of the floating floor slab plus the weight of equipment, machines, fixtures and constructions supported by the floating floor plus 25% of the specified live load.

5 D. Maximum design load calculations for isolation mat and layout to be based on the weight of the floating slab plus weight of the walls and fixtures supported by the floating slab plus 100% of the specified live load. E. Durability of rubber isolation mat to be 50 year minimum without significant degradation of performance. Part 3. Execution 3.01 EXAMINATION A. Before installation, examine alignment, smoothness and evenness of substrate. Notify [Contractor] in writing if substrate does not comply with requirements of rubber isolation mat manufacturer. B. Verify items provided by other trades are properly installed. C. Commencement of work will imply acceptance of substrate conditions PREPARATION A. Ensure installation area is free of all debris, broom clean, and dry. B. Brush or vacuum walls approximately 305 mm (12 ) up from structural floor to ensure walls are sufficiently clean to receive perimeter isolation strip adhesive INSTALLATION A General 1. Install rubber isolation mat system in accordance with manufacturer s printed instructions. 2. Co-ordinate work with related work to avoid rigid contact with the building. B Perimeter Isolation Mat Strips 1. Ensure height of perimeter mat strips are from concrete structural substrate to top of [concrete] wearing surface. 2. Adhere perimeter mat strips using bead of good quality polyurethane based panel adhesive located at approximately the middle of the mat strip. Press firmly to wall and tape vertical joints including corner joints, and horizontally around horizontal rubber isolation mat/vertical perimeter

6 isolation mat interface. Use sheathing tape or duct tape for isolation joints at these locations and at penetrations. C. Penetrations Isolation Board 1. Install penetrations isolation board around penetrations such as [piers,] [columns,] [pipes,] [drains,] [and] [electrical items] [ ]. D. Rubber Isolation Mats 1. Following rubber isolation mat manufacturer s written instructions, install mats according to layout drawings[s]. 2. Cover rubber isolation mat with minimum 6 mil polyethylene sheeting to retain concrete. Lap sheet edges minimum 75 mm (3 ) and tape watertight while ensuring application is free of wrinkles and fishmouths. 3. Place concrete wearing surface and reinforcement, including curing and finishing agents as specified in Division 3 of the specifications. Do not allow concrete [and] [rebar] to touch structure or base building. SPEC NOTE: Other wearing surfaces may be specified in lieu of concrete. Wood flooring, ceramic tile, carpet, and similar finishes may be employed. Contact Wilrep Ltd. representative for requirements. 4. When placing concrete, ensure concrete does not build up in one spot and overload rubber isolation mat. Do not roll concrete carts over rubber isolation mat. 5. After concrete has cured, use utility knife to cut excess polyethylene sheeting at wall edge and penetrations. 6. If required by local codes, caulk top of perimeter isolation board. 7. Sound isolate drains CLEANING END OF SECTION A. Upon completion of work, remove all materials, equipment and debris from site. B. Leave work area and adjacent surfaces in condition acceptable to [Consultant] [Engineer] [Architect].
