those furrows presents a slight inclination and they can also have a bottom profile shaped like a double pitch roof the support elements include lateral fastenings in their edges for being able to be screwed to a lower surface corresponding to the floor if necessary so each set of support and tile comprises a covering tile module which is connected and associated with other adjacent modules by means of a tongue and groove coupling the connection between both parts of each module is done by means of tongue portions of the support which are complemented with groove portions located on the reverse side of the ceramic parts thereby achieving a combined chemical mechanical connection the inventive covering is also wherein the plastic supports comprise a structure formed from an array of coplanar ribs and a peripheral frame with a staggered configuration said ribs being complemented with some channels located on the reverse side of the ceramic parts so that when the adhesive is poured over the contact surface between the two component bodies of the module the mechanical and chemical connection is made precisely via the said ribs and channels with the addition of the adhesive the connection between the ceramic part and the plastic support is reinforced by means of a succession of small passage recesses located in.
