24” x 24” Hardwood Deck Tile Elevating System
Altitudes Pedestal® system with hardwood deck tiles above view

The DeckWise®, Altitudes Pedestal® System has been engineered to build perfectly horizontal decking over underutilized spaces such as sloped roof tops and plaza areas. Pedestals elevate and support 24" x 24" modular hardwood deck tiles over uneven concrete, rooftops, plazas, or walkways allowing anyone to build new beautiful living spaces.

The Altitudes Pedestal® System enables anyone to easily and quickly build an elevated all-natural hardwood deck surface. Install deck tiles on sloped or uneven rooftops to hide service pipes, cabling, drains or service ducts without the need to construct extensive sub-framing. Build luxurious decking where it was once impossible into a gorgeous family or party area to enjoy for years to come.

Pedestal systems utilize a head, a base and Schedule 40 PVC pipe to make installations simple for multiple height accommodations. The Altitudes Pedestal™ System heads an bases have drainage holes for water; are exceptionally stable with 4” PVC Schedule 40 Plain End Pipe; and are resistant to freeze thaw cycles from the use of 20% Talc added to a polypropylene resin.

Altitudes Pedestal® system with hardwood deck tiles
Our system is fully compatible with WiseTile® Hardwood Deck Tiles.

Each pedestal system has the ability to accommodate multiple minimum heights. Choose from 4-5/32”, 2-21/32”, or 1-1/2” for the lowest heights (this includes PVC pipe) up to 24 inches at their maximum safe height.

Precise 3/16 inch spacer tabs are integrated into the head to produce perfect tile gap spacing and are easily punched out for deck tile placements where tabs are not needed; such as around corners or around circumferences for added support. Additional pedestals are needed when supporting heavy objects such as planters and grills.

Current minimum heights of the Altitudes Pedestal® System are:

  • SJB-4156 Screw-jack Base Pedestal: 4-5/32”
  • SPVC-2656 Stationary Base Pedestal: 2-21/32”
  • SPVC-15 Stationary Base Pedestal: 1-1/2”

Sleepers, shims and blocking can be used for shorter deck tile supports.

Cutting 4 in. PVC Schedule 40 Plain End Pipe to Size

The PVC pipe fits inside the cavity of the pedestal heads and the pedestal bases. To acquire the correct height of PVC; the head, base, and the nominal thickness of the deck tile must be subtracted from the finished elevation of the deck tile surface for accuracy. The screw-to-adjust base will provide final height adjustments or shims with the Stationary bases.

The “press fit” connection of the PVC to the heads and bases requires no gluing.

NOTE: The minimum height allowed for Altitudes Pedestals® are from 4-5/32”, 2-21/32”, or 1-1/2” for the lowest heights. Minimum height pedestals must include 1-1/2" of Schedule 40 PVC to connect the head to the base.

Locking Deck Tiles Together

1.) Lockit Down Washer™

Deck tiles are secured to the pedestal with pine tree fasteners (rated up to 166 lbs. of wind hold-down strength) and our patented adjustable Lockit Down Washer™. The washer fits into the corner kerf cut slots of deck tiles which, in turn lock and hold down deck tiles to the pedestal head.

Insert the Lockit Down Washer™ into the corner kerf cut slot of all 4 hardwood deck tiles where they meet on a pedestal. First, slide a washer into 2 tile kerf corner slots and hand thread the 3/32" stainless steel screw into the stainless steel insert of the pedestal head. Install a 3rd deck tile by sliding the washer out of the way and place over the pine tree fastener. Next install the 4th deck tile onto the pedestal's 4th corner in the same manner. Once all 4 deck tiles are in place and levelness is checked, center the washer and securely tighten the screw for maximum hold-down.

To remove a deck tile: loosen the stainless steel screw and slide the washer to the side into adjoining deck tiles and out of the way. All 4 corners of the deck tile that is to be removed, will need to have the washer loosened and slid to the side for deck tile removal.

2.) Pine Tree Fasteners

Pine tree fasteners additionally secure each deck tile to the pedestal head.

3.) Pre-drilled Holes

Pre-drilled holes under each deck tile precisly position each tile on the pedestal head.

Slope Compensation

Altitudes Pedestal® slope compensation

Slopes and Pitches

The self-leveling pedestal head can be level or adjustable for slope compensation. 0-5% slopes are easily managed by positioning the self-leveling head at the desired angle in accordance to the overall deck tile height needed.

  • 1% slope = .120 inches per foot drop
  • 2% slope = .240 inches per foot drop
  • 3% slope = .360 inches per foot drop
  • 4% slope = .480 inches per foot drop
  • 5% slope = .600 inches per foot drop

Perimeter Containment, Parapets, Blocking, and Retention Walls

Any intended installation area of a pedestal hardwood deck tile system must fit tight inside the walls of the installation cavity and be restrained and contained. Roof tops must have parapet retaining walls, concrete dividers or other structural perimeter restraint capable of resisting lateral forces including seismic and wind. Blocking must be installed where deck tiles change heights such as stepping up or down.Deck tiles and pedestals will move if all sides are not tightly fit.

Perimeter "structural" framing and edging boards located at the outside of the deck tile perimeter must also be installed to provide restraint. No movement greater than one spacer tab should be allowed at the perimeter of the deck pedestal system. Cumulative movement in excess of 3/16 of an inch will void the Altitudes Pedestal® System Limited Warranty.

Always seek the professional advice of a licensed and accredited architect prior to installation.
ALL LOCAL AND STATE BUILDING CODES MUST BE ADHERED TO AT ALL TIMES.

Installation Process

Substrate Surface

The substrate surface which will receive the deck tile pedestal system must be clean and free of any projections and debris. It must be compact and structurally capable of carrying the live and dead load projected which, if not, may impair the performance of the pedestal system. The use of protection board, insulation and waterproof membrane must meet or exceed local building codes.

Installing Deck Tiles & Pedestals

Prior to installation, verify all cavity elevations, desired pedestal heights and overall installation dimensions. Inspect the roof top substrate to confirm that it has been correctly prepared. If roof top preparation is the responsibility of others, notify the construction designer, contractor and architect in writing. Any deviations from the manufacturer's recommended installation guidelines will void warranty or create an unsafe surface. Attention to, and inspection of hardwood deck tiles and pedestals must be completed prior to installation.

Review of the deck tile pattern, layout grid, threshold starting point, and finished elevation should be shown on a plan view architectural drawing. Plans, CAD drawings and/or illustrations should be prepared and approved by an accredited architect or construction designer. Owner approval and sign-off of plans should be in writing and documented. Install deck tiles and pedestals in accordance with Altitudes Pedestal® Systems and any other product manufacturer's guidelines. Installation requirements will vary for any individual job site.


Special Considerations & Tips for Safe Installations

Planters, grills and heavy objects must have 6 pedestals underneath each deck tile for additional support. Add a pedestal to the sides of all deck tiles that will receive additional weight.

  • Pedestal bases may be trimmmed for a tight fit around a corner. DO NOT cut or trim the pedestal head
  • Conduit and services running insde the cavity below can be easily accessed by removing 1 or more tiles
  • Cut tiles to fit around conduit; use stainless steel screws from the underside to secure wood slats
  • Notch cut tile corners to fit around conduit where needed
  • Use conscruction adhesive to secure spacer tabs between tiles when not attached to the pedestal
  • Tiles must fit snug around the perimeter with no movement allowed greater than 1 tab width
  • Fill perimeter spaces with a section of tile to assure a tight fit; use construction adhesive for additional hold
  • On small tile pieces/sections around the perimeter or a radius use construction adhesive on the pedestal for additional support
  • Bottom leveling shims are not necessary
Always seek the professional advice of a licensed and accredited architect prior to installation.
