A stratified-structure laminar covering material, which can be used for example as a flooring for sports facilities, comprises an outermost layer, a bottom layer, and an intermediate layer set between the outermost layer and the bottom layer. The aforesaid layers comprise a matrix constituted by a mixture of polyolefin and thermoplastic elastomer, the matrix being substantially identical for all three layers. The matrix of the outermost layer is substantially free from fillers and has a first value of density. The bottom layer contains fillers so as to have a second value of density greater than said first value of density, and the intermediate layer contains fillers so as to have a third value of density intermediate between the first value of density of the outermost layer and the second value of density of the bottom layer.

The covering material according to claim 1, wherein the matrix of said outermost layer has a density of between 1 g/cm3 and 1.1 g/cm3. 3. The covering material according to claim 1, wherein said intermediate layer has a density of between 1.3 g/cm3 and 1.4 g/cm3. 4. The covering material according to claim 1, wherein said bottom layer has a density greater than 1.6 g/cm3. 5. The covering material according to claim 1, further comprising a stabilization layer located in a position set between any two of said outermost layer, intermediate layer, and bottom layer. 6. The covering material according to claim 5, wherein said stabilization layer is located in a position between said intermediate layer and said bottom layer. 7. The covering material according to claim 5, wherein said stabilization layer is fiber-based. 8. The covering material according to claim 7, wherein said stabilization layer is glass fiber-based or polyester fiber-based. 9. The covering material according to claim 5, wherein said stabilization layer has a mass per unit area in the range of 25-50 g/m2. 10. The covering material according to claim 5, wherein said stabilization layer is incorporated in the polyolefin/thermoplastic-elastomer matrix of the layers between which said stabilization layer is set. 11. The covering material according claim 1, wherein said outermost layer is made starting from granules. 12.

The covering material according to claim 11, wherein said intermediate layer has portions that emerge at an outermost surface of said outermost layer. 14. The covering material according to claim 1, characterized in that said polyolefin is selected out of the group consisting of polyethylene, polypropylene and/or mixtures and/or copolymers thereof. 15. The covering material according to claim 14, characterized in that said polyolefin is substantially polyethylene. 16. The covering material according to claim 14, characterized in that said polyolefin is substantially low-density polyethylene. 17. The covering material according to claim 1, wherein said thermoplastic elastomer is selected out of the group consisting of thermoplastic elastomers of styrenic origin, and mixtures thereof. 18. The covering material according to claim 17, wherein said thermoplastic elastomer of styrenic origin is substantially poly(styrene-butadiene-styrene). 19. The covering material according to claim 1, wherein said bottom layer has an outer surface presenting a microgranular appearance. 20. The covering material according to claim 1, wherein said bottom layer has an outer surface presenting groovings in the form of ribbings, feet or similar formations. 21. A multi-layer material comprising: an outermost layer having a first polyolefin matrix of a first density; a bottom layer having a second polyolefin matrix of a second density; and an intermediate layer positioned between the outermost layer and the bottom layer, the intermediate layer having a third polyolefin matrix of a third density, wherein, each of the first, second and third polyolefin matrices include a thermoplastic elastomer dispersed therein, the first density being lower than the third density, the third density being lower than the second density. 22. The multi-layer material of claim 21 wherein the first polyolefin matrix further include a plurality of pigmenting fillers dispersed therein. 23. The multi-layer material of claim 21 wherein the second matrix and the third matrix each further includes a plurality of mineral fillers dispersed therein. 24. The multi-layer material of claim 21 wherein the first density is about 1 g/cm3 to 1.1 g/cm3; the third density is about 1.3 g/cm3 to 1.4 g/cm3; and the second density is about above 1.6 g/cm3. 25.
