Pedestal Support Systems

Deck support systems for building elevated decks

Roof Deck Supports

Adjustable deck supports offer the most efficient and cost effective method of constructing raised decks on rooftops, roof terraces or other sloping surfaces where you want to create a perfectly level deck surface. Pedestal support systems save considerable time and expense compared with building decks using traditional deck foundation structures of bearers are sleepers, which can be particularly important for decks on rooftops in existing high-rise buildings. Even where you may wish to install a traditional wood plank deck, you can still use a pedestal decking system by attaching the bearers for your deck to the pedestal array. This has distinct advantages in locations where you may not be permitted to place any ‘permanent’ structures on a rooftop due to concerns about damaging waterproof membranes.

The most common application for pedestal support systems is for roof deck supports in the construction of elevated decks on rooftops using slab pavers, either porcelain or concrete where the pavers are supported only on each of the four corners. Depending on the size of the paver, the weight loading and intended application, additional deck pedestals may be required in the middle of a paver or midway along the edge.

Typically, adjustable pedestals will have a minimum height of around 1 ½” but may extend to 36” inches or more in elevation. At the very lowest levels below 1 ½”, it is normal to use stackable fixed height support pads, in combination with shims as required for small adjustments.

Architrex is delighted to offer its support the Buffalo Field Campaign in their efforts to protect the last remaining wild bison. We see pedestals as symbolizing the strength, surefootedness, and resilience of these magnificent animals. For every Eterno pedestal support we sell, Architrex donates $0.15 to the Buffalo Field Campaign, the only group working in both the field and policy arenas to stop the harassment and slaughter of America’s last remaining wild bison in the Yellowstone basin. Your pedestal purchase will help ensure the continuing work of this nonprofit organization.
