Mbrico Tile Decks consist of porcelain stoneware tiles installed without grout over aluminum tracks mounted over standard deck framing. Grooved tile edges slide onto the track, and milled “bumpers” maintain uniform spacing between tiles. The frost-resistant and color-fast tiles come in two sizes—12 inches by 24 inches and 24 inches square—and 30 colors, and do not need a sealant. Each tile can support 2,200 pounds, according to the maker. Tiles and track are delivered as a complete kit, including butyl flashing tape and stainless steel screws, for about $23 a square foot.
