PART 3

EXECUTION

3.1

EXAMINATION

Do not begin installation until substrates have been properly prepared.

If substrate preparation is the responsibility of another installer, notify Architect of unsatisfactory preparation before proceeding.

3.2

PREPARATION

Clean surfaces thoroughly prior to installation.

Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions.

3.3

INSTALLATION

Install in accordance with manufacturer's instructions.

Cast-In-Place Installation:

Physical characteristics of the concrete shall be consistent with Section 03300 while maintaining a slump range of 4 - 7 to permit solid placement of the Cast In Place Detectable/Tactile Warning Surface Tile system.

Factory-installed plastic protective sheeting must remain in place during the entire installation process to prevent the splashing of concrete onto the finished surface of the tile.

It is imperative that the installation technique eliminates any air voids under the tile. Holes in the tile perimeter allow air to escape during the installation process. Concrete will flow through the large holes in each embedment flange on the underside of the tile and will lock the tile solidly into the cured concrete.

Concrete shall be poured and finished true and smooth to the required dimensions and slope prior to the tile placement. Immediately after finishing concrete, the electronic level should be used to check that the required slope is achieved. The tile shall be placed true and square to the curb edge in accordance with the Drawings.

The Cast In Place Detectable/Tactile Warning Surface Tiles shall be tamped (or vibrated) into the fresh concrete to ensure that the field level of the tile is flush to the adjacent concrete surface. The embedment process should not be accomplished by stepping on the tile as this may cause uneven setting which can result in air voids under the tile surface. The tile field level (base of truncated dome) should be flush to adjacent surfaces to permit proper water drainage and eliminate tripping hazards between adjacent finishes.

In cold weather climates it is recommended that the Cast In Place Detectable/Tactile Warning Surface Tiles be set deeper such that the top of domes are level to the adjacent concrete on the top and sides of ramp and that the base of domes to allow water drainage. This installation will reduce the possibility of damage due to snow clearing operations.

Immediately after placement, the tile elevation shall be checked to adjacent concrete. Ensure that the field surface of the tile is flush with the surrounding concrete and back of curb so that no ponding is possible on the tile at the back side of curb.

While concrete is workable, a 3/8 inch radius edging tool shall be used to create a finished edge of concrete, then a steel trowel shall be used to finish the concrete around the tile's perimeter, flush to the field level of the tile.

During and after the tile installation and the concrete curing stage, it is imperative that there is no walking, leaning or external forces placed on the tile that may rock the tile causing a void between the underside of tile and concrete.

10.

Following tile placement, review installation tolerances to contract drawings and adjust tile before the concrete sets. Two suitable weights of 25 lb each may be required to be placed on each tile as necessary to ensure solid contact of the underside of tile to concrete.

11.

Following the concrete curing stage, protective plastic wrap is to be removed from the tile surface by cutting the plastic with a sharp knife, tight to the concrete/tile interface. If concrete bled under the plastic, a soft brush shall be used to clean the residue without damage to the tile surface.

Surface Applied Installation:

Coordinate with the Architect to ensure that the surfaces being prepared and fabricated to receive the tiles are constructed correctly and adequately for tile installation.

Set the tile true and square to the curb ramp area as indicated on the Drawings, so that its location can be marked / traced on the concrete surface. Remove tile when done marking its location.

Using a continuous rim diamond blade for concrete mounted on a grinder carefully cut vertically into the concrete following the outline of the tile to a depth of approximately 1/8 inch to 3/16 inch depth around the perimeter. This process is to reduce the risk of broken edges along the exposed finished concrete surface. DO NOT OVERCUT THE CORNERS.

Using a continuous rim diamond blade in a circular saw or hand grinder cut vertically into the concrete to create a groove inside 1/4 inch wide and 3/4 inch deep inside of the tile perimeter tracing to accept the return flanges at the perimeter of the tile.

Dry fit the tile to ensure the tile sits properly in the grooved area.

Concrete surface to receive the Surface Applied Detectable/Tactile Warning Surface Tile shall be mechanically cleaned with a diamond cup grinder or shot blaster to remove any dirt or foreign material. This cleaning and roughening of the concrete surface should include the entire area to receive the tile. The concrete and tile should then be cleaned with a clean rag soaked in Acetone.

Use Armor-Bond adhesive on the backside of the tile. Place a bead of Armor-Bond on the underside around the perimeter of the tile and between domes along the longest dimension of the domes. The contents of 2 tubes minimum should be used for every 2x4 or larger tile. Place tile on prepared surface.

With the tile in place, stand on the tile, and using a 1/4 inch drill bit drill through tile into the substraight to a depth of 3". Remove the tile and vacuum or blow the dust from the holes. Install the anchors and place the tile. While standing on tile install the stainless fasteners carefully, DO NOT OVERTIGHTEN THE FASTENERS.

Following the installation of the fasteners, the concrete dust should be vacuumed, brushed or blown away from the tile's surface and adjacent concrete. Using Acetone on a rag, wipe the concrete around the tile's perimeter to ensure a clean, dry surface to receive perimeter sealant.

10.

Armor-Seal perimeter caulking sealant should be applied following the sealant manufacturer's recommendations. Tape all perimeter edges of the tile back 1/16" from the tile's perimeter edge and tape the adjacent concrete back 1/2" from the tile's perimeter edge to maintain a straight and even caulking line. Apply sealant around tile perimeter using care to work sealant into any void between the tile and concrete interface. Tool the perimeter caulking with a rounded plastic applicator or spatula to create a cove profile between the tile and adjacent concrete. Remove tape immediately after tooling perimeter caulking sealant.

11.

Do not allow foot traffic on installed tiles until the perimeter caulking sealant has cured sufficiently to avoid tracking. Curing time is weather dependant (average cure time at 75 degrees F is 30 minutes). Adhesive or caulking on the surface of the Advantage Tile can be removed with Acetone.

3.4

PROTECTION

Protect installed products until completion of project.

Protect tiles against damage from rolling loads following installation by covering with plywood or hardwood.

Clean Tactile Tiles not more than four days prior to date scheduled for inspection intended to establish date of substantial completion in each area of project. Clean Tactile Tile by method specified by Tactile Tile manufacturer.

Comply with manufacturers maintenance manual for cleaning and maintaining tile surface and it is recommended to perform annual inspections for safety and tile integrity.

Touch-up, repair or replace damaged products before Substantial Completion.

3.5
