Pedestal Placement - At Curved and Angled Walls
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”.
The number of pedestals you’ll require for your project depends on the following:
- The total number of tiles or pavers used.
- The dimensions of the tiles or pavers.
- The weight of the tiles or pavers – larger or heavier pavers may require an additional central pedestal per paver.
- The shape of the area to be covered – the more irregular it is shaped, the more pedestals you’re likely to need.
- The anticipated loading on the deck.
- The amount of pedestrian traffic anticipated (commercial applications).
- The finished height of the deck.
As a guide, the following formula can be used if the area is a simple rectangle or square:
- Count the number of pavers or tiles along the width and the depth and add one to each of these numbers.
- Multiply these numbers together to give the minimum number of pedestals required.
