Solutions For Roof Decks And Landscapes

When your tools include pedestal systems the challenges of modern architecture become opportunities. Pedestals make negotiating roof decks and other challenges easy and more importantly, they become the highlights of the build. The illustration to the left shows Eterno PR series pedestals with tile heads supporting porcelain pavers. Fascia support brackets are used to complete the design with a high level of fit, finish, and cohesive design.

Pedestals Are The Right Way To Install Conventional Decking Over Roof Membranes

Pedestal roof deck supports are the proper way to build with conventional decking over a roof membrane. Eterno supports with the Wood-Joist Adapter allow a 2×4 to lay flat over the supports so that decking may be fastened to it. Any decking can be used with this system. Screws, hidden fasteners or plugs may all be used to fasten to the 2×4. A special aluminum T-Slot joist with accompanying clips are optional.
Pedestals take the place of all forms of sleeper joists. No more taper-cutting 2x down to a finite point along with the dubious question of fasteners. Solid wood joists laid on membrane or coating can cause stresses and compromise waterproofness. Pedestals are designed to evenly distribute weight without pinch points or abrasion potential.
