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.

** NOTE TO SPECIFIER ** Select the installation system required for Detectable/Tactile Warning System(s) specified from the following paragraphs and delete the paragraph(s) not required.

Replaceable 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. Voids in the tile perimeter allow air to escape during the installation process. Concrete will flow round and encase the hex shape anchor to provide permanent and consistent anchor / tile placement

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 Relplaceable 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 Replaceable 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. Suitable weights 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.

12.

Tiles can be cut to custom sizes, or to make a radius, using a continuous rim diamond blade in a circular saw or mini-grinder. Use of a straightedge to guide the cut is advisable where appropriate.

13.

Any portion of the sound-amplifying plate on the underside of the tile, which are dislodged during handling or cutting, should be replaced and secured with construction adhesive. The air gap created between these plates and the bottom of the tile is important in preserving the sound on cane audible properties of the Armor-Tile system as required in various jurisdictions.

Replaceable Cast-In-Place Replacement Procedure

Remove the Tamper Proof Stainless Steel fasteners with a 5mm tamper proof hex bit.

Using a rubber mallet, tap the top surface of the tile in grid pattern to remove the concrete bond to the tile

Remove the existing tile (use of a pry bar may be required) by starting in a corner, lift the tile out of the installed position

Remove any debris from the tile impression in the concrete. A leaf blower or broom will work well

Place the new tile (same size as original) into the existing impression within concrete and insert stainless steel fasteners (supplied by tile manufacturer) in all fastener locations. Be sure to insert fasteners so that the top surface of the fastener head is below the micro texture of the tile and the tile is tight to the underlying concrete.

Cast-In-Place Installation:

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.

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.

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.

12.

If desired, individual tiles can be bolted together using 1/4 inch (6 mm) or equivalent hardware. This can help to ensure that adjacent tiles are flush to each other during the installation process. Tape or caulking can be placed on the underside of the bolted butt joint to ensure that concrete does not rise up between the tiles during installation. Any protective plastic wrap which was peeled back to facilitate bolting or cutting, should be replaced and taped to ensure that the tile surface remains free of concrete during the installation process.

13.

Tiles can be cut to custom sizes, or to make a radius, using a continuous rim diamond blade in a circular saw or mini-grinder. Use of a straightedge to guide the cut is advisable where appropriate.

14.

Any sound-amplifying plates on the underside of the tile, which are dislodged during handling or cutting, should be replaced and secured with construction adhesive. The air gap created between these plates and the bottom of the tile is important in preserving the sound on cane audible properties of the Armor-Tile system as required in various jurisdictions.

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.

Surfaces 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.

Immediately prior to installing the Surface Applied Detectable/Tactile Warning Surface Tile, the concrete surfaces must be inspected to ensure that they are clean, dry, free of voids, curing compounds, projections, loose material, dust, oil, grease, sealers and determined to be structurally sound and cured for a minimum of 30 days.

Using Acetone, wipe the backside of the tile around the perimeter and along the internal cross pattern, to remove any dirt or dust particles from the area to receive the adhesive.

Apply Armor-Bond adhesive to the backside of the tile, following the perimeter and internal cross pattern established by the tile manufacturer. Sufficient adhesive must be placed on the prescribed areas to have full coverage across the 2 inch (51 mm) width of the adhesive locator and shall be applied to within 1/4 inch (6 mm) continuously around the perimeter edge of the tile. The entire tube of adhesive shall be applied to the back of each tile, sizes 24 inch by 36 inch (610 mm by 914 mm) and greater.

Set the tile true and square to the curb ramp area as detailed in the design drawings.

Working from the center of the tile outwards, proceed to drill and install all fasteners in the tile's molded recesses.

Standing with both feet applying pressure around the molded recess provided in the tile, drill a hole true and straight to a depth of 3-1/2 inches (89 mm) using a 1/4 inch (6 mm) masonry drill bit. Drill through the tile without hammer option (on the drill) until the tile has been successfully penetrated, then with hammer option (on the drill) to drill into the concrete. Maintaining foot pressure on both sides of the hole while drilling prevents concrete dust from accumulating between the tile and concrete which can affect the tile being installed flush and may compromise installation integrity.

10.

Immediately after drilling each hole, before moving on to the next, and while still applying foot pressure, mechanically fasten tiles to the concrete substrate using a leather bound or hard plastic mallet to set the fasteners. Ensure the fastener has been placed to full depth in the dome, straight, and flush to the top of dome. Drive the pin of the fastener with the mallet, taking care to avoid any inadvertent blows to the truncated dome or tile surface.

11.

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.

12.

Armor-Seal perimeter caulking sealant should be applied following the sealant manufacturer's recommendations. Tape all perimeter edges of the tile back 1/16 inch (1.59 mm) from the tile's perimeter edge and tape the adjacent concrete back 1/2 inch (6 mm) 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.

13.

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 Armor-Tile can be removed with Acetone.

14.

If installing adjacent tiles, note the orientation of each tile. Careful attention will reveal that one of the long edges of the tile is different than the other in regard to the tiny dotted texture. You may also note a larger perimeter margin before the tiny dotted texture pattern begins. Consistent orientation of each Armor-Tile is required in order that the truncated domes on adjacent tiles line up with each other.

15.

In order to maintain proper spacing between truncated domes on adjacent tiles, the tapered edge should be trimmed off using a continuous rim diamond blade in a circular saw or mini-grinder. The use of a straightedge to guide the cut is required. All cuts should be made prior to installation of the tiles. If installing adjacent tiles, care should be taken to leave a 1/8 inch (3 mm) gap between each tile to allow for expansion and contraction.

16.

If tiles are custom cut to size, if pre-molded recesses (to receive fasteners) are removed by the cut, or to maintain a tight installation to the substrate then any truncated dome can be center-drilled with a 1/4 inch (6 mm) masonry drill bit to create a through hole, and the through hole must be countersunk with a suitable carbide countersink bit to receive mechanical fasteners. Care should be taken to not countersink too widely or deeply. Fasteners should be flush with the top of the truncated dome when countersunk properly.

Modular Tile 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.

Layout Modular Paver Detectable/Tactile Warning Surface Tiles and joints to fit existing spacing indicated on the Drawings.

Immediately prior to setting the Modular Paver Detectable/Tactile Warning Surface Tiles, use an electronic level to check that the required slope is achieved. Place tiles true and square to the curb edge in accordance with the Drawings.

Modular Paver Detectable/Tactile Warning Surface Tiles shall be tamped or vibrated onto an engineered crushed gravel substrate or a properly prepared mortar bed to ensure that the field level of tile is flush to the adjacent surfaces. Place the tile field level (base of truncated dome) flush to adjacent surfaces to permit proper water drainage and eliminate tripping hazards between adjacent finishes. The maximum tolerance for elevation differences between tile and adjacent surface is 1/16 inch (1.6 mm).

Vacuum clean, mechanically abrade and solvent wipe the joints between Modular Paver Detectable/Tactile Warning Surface Tiles.

Place 3/8 inch (9.5 mm) diameter foam rope at bottom of all joints.

Tape off each side of leading edge groove in preparation for the self leveling urethane sealant.

Apply urethane sealant in joints filling flush to top of Modular Paver Detectable/Tactile Warning Surface Tiles then remove tape prior to curing.

Directional Tile 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.

Saw cut two 3/4 inch (19 mm) deep grooves to accept return flanges on each side of tile, remove dust on tile and substrate.

Using Acetone, wipe the backside of the tile around the perimeter, to remove any dirt or dust particles from the area to receive the adhesive.

Apply Armor-Bond adhesive to the backside of the tile. Sufficient adhesive must be placed on the underside of the tile for adequate adhesion.

Set the tile true and square in the area as detailed in the design Drawings.

Working from the center of the tile outwards, proceed to drill and install all fasteners in the tile's molded recesses.

11.

Guidance Tile Installation:

It is imperative that the installation technique eliminates any air voids under the tile.

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. Tile shall be placed true and square accordance with the Drawings.

Guidance Tiles shall be tamped 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.

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.
