PART 3    EXECUTION
3.1	EXAMINATION
A.	Do not begin installation until substrates have been properly prepared.
B.	If substrate preparation is the responsibility of another installer, notify Architect of unsatisfactory preparation before proceeding.
3.2	PAVER/TILE INSTALLATION
A.	Examination: Prior to starting work inspect the substrate to ensure that it has been properly prepared to accept the Tile Tech Pedestal System. The substrate and or surface shall be clean and free of any projections and debris which may impair the performance of the pedestal and or the deck system. Verify all elevations, required pedestal heights and deck dimensions. Commencement of work shall imply acceptance of surfaces and deck conditions.
B.	Preparation: The substrate surface that will receive the Pedestal System shall be well compacted (on Grade) or structurally capable of carrying the dead and live loads anticipated.
1.	Insulation over the membrane: (Option 1) Insulation and/or protection board (if specified) shall be applied over the waterproofing substrate and/or specified drainage mat. Install the system according to the membrane manufacturer's recommendations and specifications.
2.	Insulation under membrane: (Option 2) Insulation required to be installed within a roofing system below deck supports shall meet the roofing membrane manufacturers' specifications and shall have a minimum core density of 60 psi (414 kPa).
3.	Protection Board: (for asphalt type systems used over waterproofing) Full coverage 1/8 inch (3 mm) asphaltic composition protection board is recommended. When protection is specified only under the pedestal cut protection board pads to extend beyond the outside perimeter of the pedestal system base or buffer pad by a minimum of two inches (51 mm).
4.	Drainage Mat: (when desired or specified) Install drainage mat according to the manufacturers recommendations to avoid crushing.
C.	Install in accordance with Tile Tech Inc and other contributing manufacturer's instructions. Installation requirements vary for each individual project site. Decking paver or tile used, pattern, grid layout, starting point, and finished elevation shall be shown on plan view shop drawings, which have been prepared and approved by the designer, installing contractor and/or Owner.
D.	Grid Layout and Elevations:
1.	Once the starting point and the finished elevation of the deck surface have been determined, the "Top of Pedestal Elevation" (finished elevation less decking paver or tile thickness) is established and marked around the perimeter using a transit water level or laser leveling device.
2.	Precise measurements shall be taken and deck area shall be accurately defined. Mark off and ' square up' all outside edges with control lines using "snapped" chalk lines. Mark two lines that are perpendicular to each other across the deck area. Continue to mark a grid of lines in both directions marking the location of each pedestal. Use the control lines as references to periodically check and assure a square layout during installation.
3.	Next, a pedestal shall be placed where each measured grid line meets the perimeter. Remove two spacer tabs in line with one another atop each pedestal system placed around the perimeter. Remove all four spacer tabs at corners.
4.	Adjust each pedestal height to the "Top of Pedestal Elevation" marked on the perimeter. Position the pedestal as close to the edge of the perimeter as possible, with the two remaining spacer tabs aligned with the grid line. Using the elevation marked on the perimeter, stretch a mason's line along and slightly ahead of the second row of pedestals. A laser leveling device may also be used for this purpose.
5.	On larger decks, it is recommended that Tile Tech Pedestal System be pre-assembled and pre-set to the proper elevation and placed in position prior to the installation of decking paver or tile.
6.	As the pedestals located along the grid lines are loaded with porcelain pavers or tiles, fine vertical height adjustment can be made by inserting and rotating, from the top, a T-handle Hex Key in to the Uni-Insert of the Pedestal assembly. Clockwise rotation of the Uni-Insert will raise the bearing surface and the deck. Counter-clockwise rotation will lower the top bearing surface and deck.
7.	Always maintain adequate thread engagement. Tile Tech Pedestal Uni-Insert contains a locking tab that will not allow the screw to extend past its maximum extension. Never use if the locking tab is broken. If the height required goes beyond the Uni-Insert limit re-cut PVC pipe to the correct height and re-assemble the pedestal using the correct size pipe.
8.	Slight irregularities in decking paver or tile thickness can be compensated for by using one to two shim segments. Place on top of the pedestal, under the corner(s) of the decking paver or tile. Use no more than two shims on top of the pedestal and always adhere quartered (1/4) wedges with construction adhesive.
9.	Stak-Cap Pedestal can be used for limited and or fixed height requirements. Complete deck and grid layout as instructed above. Stack no more than five fixed height Stak-Cap Pedestals together and place in lieu of Uni-Just Pedestals where needed. Stak-Cap Pedestal can also be used with PVC pipe to reduce cost. Spacer tabs can be removed to accommodate perimeter and corner support locations.
E.	Slope and Height Compensation:
1.	Stak-Cap Pedestals can provide limited slope and height compensation to maintain a level decking surface over sloping substrates and is accomplished using a combination of the following:
a.	Rotate and stack one cap in relation to another to change slope and add height. Each cap will add 1/2 inch (13 mm) of height and provide 1 percent slope. Stack no more than 5 caps.
b.	Can also be used with PVC Pipe cut to required height of maximum of 6 inches (152 mm).
2.	Uni-Just Pedestals can provide both slope and height compensation to maintain a level decking surface over sloping substrates and is accomplished using a combination of the following: 
a.	PVC Pipe cut to varying lengths to compensate for general height requirements.
b.	Screw extension for precise height adjustment.
c.	Self-Leveling cap that pivots and tilts in any direction for slope compensation from 0 percent to 4 percent.
3.	Tile Tech Pedestals are designed to be rotated for final precise adjustment when they are fully loaded. Pedestals shall be leveled in each succeeding row as the installation proceeds. Final height adjustment or maintenance is easily made by simply using a T-handle Hex Key that allows you to adjust the pedestals without removing the Porcelain Pavers. T-handle Hex Key is inserted between the four paver corners to engage Uni-Insert portion and is adjusted clockwise or counter clockwise to level as needed.
4.	Uni-Shims may be used in multiples, whole or quarters, and placed under the pedestal base or on top the pedestal cap to level pedestals. Use a small amount of construction adhesive to adhere sections of shims and/or whole shims to each other or to the pedestal. DO NOT use construction adhesive to adhere pedestal or shims to insulation, roofing or waterproofing membrane. Additional sections of shims may be used and shall be available for regular maintenance.
5.	Once level, IPE Lock Washer shall be used so secure the tiles to the pedestal system. Insert special washer in to the slot in the corners of 3 tiles than install the 4th tile.
