You won’t need a tile setter with the Mbrico Tile Deck System for exterior decks. Aluminum tracks are screwed to the framing, and notched porcelain tiles slide into place between them. Fiberglass plates epoxied to the tiles’ undersides raise their breaking strength to 4,000 psf. The company says that the tiles have non-slip surfaces, are harder than granite, have a moisture absorption rate of less than .05%, and won’t freeze, thaw, or stain. They’re also self-gapping, which creates drain slots where you would normally see grout. Costs range from $25 to $27 per square foot. mbricotiledecks.com
