The foot comprises points (20, 22) integrated with the foot and extending from the support face. The points penetrate an inner side of the substrate for anchoring the foot on the substrate. The substrate comprises polyurethane or polystyrene. An independent claim is also included for a concrete slab producing assembly comprising a concrete slab is cast on a substrate.
