Bison Versadjust pedestals can be used to support conventional wood framing, though in the photo, they are being used to support large-format tile.
Bison Versadjust pedestals have an adjustable screw thread that allows them to be set to a predetermined height.
To avoid damage to the roofing, the author’s crew prefabricated modular 4-by-4-foot deck grids on the ground, stacked them on pallets, and lifted them up to the rooftop with a crane.
Once installed on top of the pedestals, the grids were fastened together with long structural screws.
The pedestal-supported deck grids wrap around a 120-square-foot bocce court. Steel stanchions for the railing system (to the right of the deck) were installed before the torch-down roofing.
