The tile comprises a plate 1 made of sheet steel with a bottom 2 having a juxtaposable outline and a peripheral rim 3, which respectively form the top and the sides of the tile, a concrete body 5 filling the plate 1 flush with the rim 3 with embedded reinforcement 4. The external face 2a of the bottom is covered with a wear-resistant layer 2a typically made of titanium oxide/alumina ceramic. The tiles are manufactured in two stages: during the first stage, in the factory, the plate 1 is formed and provided with the wear-resistant layer 2a, and the reinforcement 4 is cut out from expanded metal. After delivery of the plates and reinforcement, of limited weight, a concrete mortar 5 is poured into the plate with positioning of the reinforcement 4. After setting, the plate is turned over and laid on the sand 10. <IMAGE>
