Silca System’s structural panels can support a wide range of finished deck surfaces, including tile, brick, stone, and concrete pavers. Made in Ohio from all recycled PC-ABS—a type of plastic—the 16-by-18 1/8-inch 1 1/2-inch-thick grates are screwed to 16-inch-on-center framing and will support 260 pounds per square foot, according to the company. Pavers are set directly on the grates, with gaps between pavers typically left open. Alternatively, a geotextile material can be installed on the grates and the gaps filled with polymeric sand.
