Disclosed is an article consisting of at least two sheets stacked and welded to define a paving including at least three tiles, each having at least three sides and vertices, arranged to define a plane, the tiles being adjacent and connected to each other by at least one of the sides, the tiles including at least one compartment including at least a material absorbent to an aqueous medium or a filler material, the tiles being closed and connected to each other by at least one weld. The weld includes a frangible line with a series of weakening welds and junction points or a pre-cut bordered to either side with a mix weld, the mix weld being broadened close to the vertex of each tile so the corner of the tiles is reinforced by an enlarged weld surface area. Also disclosed are a production method and a device. 11422.
