Abstract: A modular floor cover for a garage floor, made of a plurality of strips of impermeable ribbed matting. The strips are laterally joined to one-another by elongated moldings. A first series of elongated joiners encloses common bordering edges of adjacent strips of ribbed matting, raising the longitudinal edges by a thickness of a sole member of these moldings. A second series of joiners is placed under all transversal edges of the strips, thereby raising the transversal edges. A basin is formed in a central region of the floor cover to retain water, slush and other fluids falling off a vehicle parked over this floor cover.
