Abstract: Plastic tiles are combined with troughs to cover a wooden deck. The U-shaped troughs are laid across the deck in parallel and are slightly spaced apart to form gaps between them. Each tile comprises a rectangular upper block having downwardly depending legs. The block stands on two adjacent troughs and bridges the gap. Rainwater moves through the cracks between the tiles and is received in the troughs, which form sluice-ways for conveying it to the edge of the deck for release. The block has a forwardly projecting, narrow protrusion positioned to register with the gap. The protrusion forms a laterally extending channel, for conveying water across the gap to the troughs, and a hole through which a screw may be driven to affix the tile to the wood of the deck at the gap. The protrusion fits beneath the rear end of the next tile so that the screw is isolated from the water. The assembly of tiles and troughs prevents water reaching the wood of the deck.
