Definitions

• the present invention relates to a method for making a flooring, a flooring, in particular a flooring for outdoor areas, and a kit for making a flooring.
• the Applicant has found that the current technical solutions which are directed towards producing floorings for outdoor areas are particularly subjected to instability over time with a resultant loss of the desired self-locking. Therefore, the Applicant has understood the opportunity and need for producing floorings which are capable of conserving over time a specific regularity of the surface thereof, therefore withstanding external forces and stresses.
• the Applicant has observed that the current floorings may be subject to a respective aesthetic degradation as a result of the quantity of water which runs off and/or pools on the surface thereof.
• the present invention is directed towards a flooring, in particular an outdoor flooring, comprising:
• the present invention may further have at least one of the preferred features set out below.
• the granules are screened so as to obtain grit having a grain size (in particular a mean grain size) between 1 and 3 mm, extreme values preferably being included.
• a grain size in particular a mean grain size
• this density is determined according to the standard UNI EN 12620.
• each filler comprises exclusively grit having a grain size between 1 and 5 mm, more preferably between 1 and 3 mm.
• At least 80% by weight of the content of each cavity is grit having a grain size between 1 and 5 mm, more preferably between 1 and 3 mm.
• At least 90% by weight of the content of each cavity is grit having a grain size between 1 and 5 mm, more preferably between 1 and 3 mm.
• the filler received in the cavity extends substantially up to an upper face of the manufactured products which delimit the cavity, the upper face being directed at the side opposite the substructure.
• the manufactured products are at least one of slabs, paving blocks and grit.
• the flooring has a permeability coefficient which is greater than or equal to 1x10 -3 m/s, according to UNI CEN ISO/TS 17892-11 with variable load, at the filler which is received in the relevant cavity.
• a method for making a flooring preferably an outdoor flooring.
• the method 100 comprises a step 101 of providing and breaking up at least one stone so as to obtain granules of the at least one stone.
• the grit 1 has a grain size between 1 and 3 mm according to the standard UNI EN 12620.
• the method 100 for making a flooring comprises a step 103 of providing, in particular laying, a substructure 2 on a surface 3 of a piece of ground.
• the substructure comprises one or more layers of materials positioned one above the other.
• the method may provide for putting into operation a layer of geotextiles and, subsequently, the laying and tamping down of a layer of bedding sand of the substructure 2.
• the thickness of the manufactured products 4a, 4b is greater than or equal to 50 mm, more preferably it is between 30 and 170 mm.
• the thickness (in mm) of the manufactured products 4a, 4b corresponds to one of: 60, 75, 80, 85, 90, 110, 150.
• the method 100 comprises a step 105 of positioning on the substructure 2 the plurality of manufactured products 4a, 4b,... one near another so as to define a plurality of cavities 8 which are open at a side opposite the substructure 2, each cavity being delimited by relevant first manufactured product 4a and second manufactured product 4b which are adjacent to each other of the plurality of manufactured products.
• the manufactured products of the plurality of manufactured products 4a, 4b,... have the respective upper face 5 directed at the opposite side to the substructure 2.
• each pair of adjacent manufactured products 4a, 4b delimits a cavity 8 (also called a joint).
• the cavity 8 therefore extends between two adjacent manufactured products 4a, 4b and the extent of the cavity 8 between the first manufactured product 4a and the second manufactured product 4b adjacent to the first manufactured product 4a is preferably less than or equal to 80 mm, more preferably it is between 1.5 mm and 4 mm.
• the plurality of manufactured products 4a, 4b are positioned on the substructure 2 inside an area which is delimited by peripheral elements (such as, for example, kerbs or walls) fixed to the ground.
• the step 107 allows a manufactured product 4a of the two-layer type to be obtained, in a state provided with a finishing layer (that is to say the second layer) serving to confer on the flooring 200 specific mechanical, chemical, physical, ergonomic, aesthetic and durability characteristics and performance levels provided by the granules contained in the second inert materials used.
• a finishing layer that is to say the second layer
• the granules of the second inert materials correspond in chromatic terms and/or in terms of material and/or grain size to those of the grit 1.
• the granules of the second inert materials correspond to granules of marble and/or porphyry.
• the first inert materials comprise sand of natural origin constituted by clasts which are mainly broken up of a carbonate type (limestone and dolomite) and clasts which are broken up of a mainly carbonate type (carbonate rocks of the micritic and dolomite limestone types) and secondarily of a silicate type (intrusive and effusive granite rocks such as granite and porphyry) .
• clasts which are mainly broken up of a carbonate type (limestone and dolomite) and clasts which are broken up of a mainly carbonate type (carbonate rocks of the micritic and dolomite limestone types) and secondarily of a silicate type (intrusive and effusive granite rocks such as granite and porphyry) .
• the external surface of the second layer 10 corresponds to the upper face 5 of the manufactured product.
• the pressure applied by the fluid to the external surface of the second layer 10 is less than or equal to 3 bar, more preferably between 2.5 and 3 bar.
• the step 107 therefore allows a manufactured product 4a of the single-layer type to be obtained, serving to confer on the flooring 200 specific mechanical, chemical, physical, ergonomic, aesthetic and durability characteristics and performance levels provided by the granules contained in the inert materials used.
• the vibro-compression step provides for transmitting horizontal and/or vertical vibrations and/or vibrations in accordance with an elliptical or circular trajectory to the mould by means of a vibrating device.
• the vibro-compression step is characterized by vibrations with a duration less than or equal to 2 seconds, preferably between 1 and 2 seconds.
• the pressure applied by the fluid to the external surface of the admixture is less than or equal to 3 bar, more preferably between 2.5 and 3 bar.
