Each tile is 1" x 16" x 16" nominal (1.78 square foot), and the tiles weighs roughly 11 pounds per square foot, which is a total approximate weight of 20 pounds per tile. Although DekTek tiles weigh a little more than composite decking, most standard wood-framed decks are sufficient to support the DekTek pavers. You can ask your local lumber yard if the wood joists are sufficient? They usually have engineering facts to verify the load capacity of your existing deck.
