For rooftop decks, pavers are typically laid over adjustable height supports to ensure a perfectly level deck surface over substrates which may slope in multiple directions for drainage. This also enables ready access to drains, permits pipework and cabling to be hidden and ensures the surface membrane is readily accessible for inspection and maintenance.
For locations subject to strict fire codes, we now offer a range of totally non-combustible paver supports – the IGNO range.
At the lowest elevations, typically at door thresholds, fixed height rubber support pads can be used to support the pavers, permitting a clearance as low as 1 ¼” with ¾” thick pavers. Pads can be stacked to build the support height up to approx. 1 ½”, after which adjustable height pedestals can be employed.
With plank style pavers 8”, 12” or 16” wide, a pedestal supported rail system is used to provide the required support, offering the added benefit of more lateral stability for the pavers. Steel rails are supported by adjustable height pedestals with pavers placed over the rails, seated on pedestal heads slid into position along the rail.
