Guidelines for pedestal installations

Basic Requirements

With any elevated deck installation using a pedestal system, the following basic requirements must be met.

  • Decks must not exceed the load capacity of the pedestals.
  • The substrate should slope slightly to give positive drainage.
  • Roof decks must comply with all local building codes including fire regulations and wind uplift.
  • Any area not bounded by a parapet or wall must be ‘boxed-in’ so the pavers cannot move.
  • Any gaps around the perimeter must not exceed 1/8”.

Porcelain or Concrete Paver Installation

The basic procedure for laying either porcelain, stone or concrete pavers over a pedestal system is essentially the same.
See the video below for the step by step procedure in laying porcelain pavers over Eterno pedestals.

The video shows the base of the pedestals installed directly against the perimeter wall being cut. This is typically only required where the pedestal heads need to be as close to the wall as possible e.g.:

a. when the pedestals are supporting a narrow section of cut paver (less than approx. 12″ wide)

b. where a cant strip is installed at the foot of the perimeter wall which restricts the pedestals being placed directly against the wall.

It is essential to leave a small gap (1/8″ min) between the wall and the edge of the pavers. We recommend the spring loaded stainless steel Eterno perimeter clips as shown in the video which are specifically designed to maintain a consistent gap around the perimeter by gently holding pavers against pedestal head spacer tabs, preventing paver movement after the install and possible damage from shifting pavers rubbing against the wall.

Structural Wood Tile Installation

Our structural wood tiles are produced with a slot in each corner to accept a special fixing device. This integrated screw and washer assembly secures the wood tiles to the Eterno pedestals without penetrating or damaging the wood.

The screw is inserted as follows. Firstly place the pedestal under two adjacent pavers and level the pavers using the adjustment tool.
Move the pedestal slightly towards you and insert the fastening screw into the hole in the center of the pedestal head.
Screw it down using a Pozidriv #2 bit  (not a Philips bit) until the washer is level with slot cut in the tiles.
Push the pedestal back towards the tiles so the tabs on the head butt firmly against the tiles and the washer engages the slots.

Install the other two tiles on the pedestal, then tighten the screw with a screwdriver to secure the corners of all four tiles.

Note that although the height adjustment tool cannot be used to adjust the height of the pedestal after the screw has been inserted, you can still adjust the pedestal height if required by turning the pedestal base.
