Description

Domaine techniqueTechnical area

L'invention concerne un revêtement de gazon, en particulier un revêtement de gazon artificiel.The invention relates to a turf covering, in particular an artificial turf covering.

Technique antérieurePrior art

Le gazon artificiel est de plus en plus utilisé, en particulier en milieu urbain. Un tel gazon permet en effet de modifier l'aspect général d'un lieu, en particulier d'un lieu extérieur, tout en nécessitant un entretien minime.Artificial turf is used more and more, especially in urban areas. Such a law makes it possible to modify the general appearance of a place, in particular of an outside place, while requiring minimal maintenance.

Le gazon artificiel est souvent soumis aux intempéries, en particulier à la pluie.Artificial turf is often subject to inclement weather, especially rain.

Pour éviter la stagnation de l'eau de pluie, il est courant de préparer le sol sur lequel un revêtement de gazon artificiel sera placé de sorte que l'eau de pluie puisse être drainée. En général, des éléments, par exemple des grains de sable de gros diamètre et/ou des graviers, sont positionnés sur le sol, puis recouverts par le revêtement, ce qui permet de former un tampon entre le revêtement et le sol. Cependant, l'installation de ces éléments nécessite souvent l'intervention d'un professionnel pour que le drainage de l'eau de pluie puisse être efficace.To avoid stagnation of rainwater, it is common to prepare the soil on which an artificial grass covering will be placed so that rainwater can be drained. In general, elements, for example grains of sand of large diameter and / or gravels, are positioned on the ground, then covered by the covering, which makes it possible to form a buffer between the covering and the ground. However, the installation of these elements often requires the intervention of a professional so that rainwater drainage can be effective.

Il existe un besoin pour un moyen facile à installer permettant de drainer efficacement un liquide, notamment de l'eau de pluie, tombant ou se répandant sur un revêtement de gazon artificiel.There is a need for an easy-to-install means for effectively draining a liquid, especially rainwater, falling or spreading on an artificial turf.

Un but de la présente invention est de répondre, au moins partiellement, à ce besoin.An object of the present invention is to respond, at least partially, to this need.

Résumé de l'inventionSummary of the invention

L'invention propose, à cet effet, un revêtement de gazon artificiel comportant, superposées les unes aux autres selon la direction de l'épaisseur dudit revêtement :

  • une nappe de support comportant, de préférence constituée de :
    • une feuille inférieure perméable à l'eau de pluie, destinée, dans une position de service, à s'étendre à plat sur le sol et à former une barrière à la pousse des végétaux;
    • un grillage, apte à drainer de l'eau de pluie, fixé à ladite feuille inférieure;
    • de préférence, une feuille supérieure fixée au grillage, perméable à l'eau de pluie; et
  • une couche de gazon artificiel en contact avec ladite nappe de support.
The invention proposes, for this purpose, an artificial turf covering comprising, superimposed on each other in the direction of the thickness of said covering:
  • a support ply comprising, preferably consisting of:
    • a rain permeable bottom sheet, intended, in a service position, to lie flat on the ground and to form a barrier to plant growth;
    • a screen, adapted to drain rainwater, fixed to said lower sheet;
    • preferably, an upper sheet fixed to the mesh, permeable to rainwater; and
  • a layer of artificial grass in contact with said support ply.

Comme on le verra plus en détail dans la suite de la description, ce revêtement permet de drainer efficacement l'eau de pluie de sorte qu'elle ne stagne pas dans le revêtement.As will be seen in more detail in the following description, this coating makes it possible to effectively drain rainwater so that it does not stagnate in the coating.

De préférence, la nappe de support forme une pièce monobloc. Ainsi, son positionnement est rendu plus simple et ne nécessite pas de faire appel à un professionnel. Elle peut aussi être en plusieurs parties. En particulier, la feuille supérieure et/ou la feuille inférieure peuvent être initialement séparées du grillage.Preferably, the support ply forms a single piece. Thus, its positioning is made simpler and does not require the use of a professional. It can also be in several parts. In particular, the upper sheet and / or the lower sheet can be initially separated from the mesh.

De préférence, la nappe de support est souple, c'est-à-dire qu'elle peut être enroulée sur elle-même, sous la forme d'un rouleau, sans rupture.Preferably, the support ply is flexible, that is to say that it can be wound on itself, in the form of a roll, without breaking.

Un revêtement selon l'invention peut comporter une ou plusieurs des caractéristiques optionnelles suivantes :

  • les bourrelets inférieurs et/ou les bourrelets supérieurs présentent une hauteur, mesurée selon la direction de l'épaisseur du revêtement, supérieure à 1 mm, préférentiellement supérieure à 1,5 mm et/ou inférieure à 4 mm, préférentiellement inférieure à 3 mm ;
  • le grillage est fixé à la feuille inférieure et à la feuille supérieure par des points de collage espacés les uns des autres de plus de 1 cm, préférentiellement de plus de 2 cm, préférentiellement de plus de 3 cm et/ou de moins de 5 cm, préférentiellement de moins de 4 cm ;
  • la feuille inférieure et/ou la feuille supérieure sont en un non-tissé et présentent une épaisseur supérieure à 0,2 mm, préférentiellement supérieure à 0,5 mm et/ou inférieure à 2 mm, préférentiellement inférieure à 1,5 mm ;
  • la couche de gazon artificiel est fixée à la nappe de support, de préférence par collage, ou est disposée de façon amovible sur ladite nappe ;
  • le revêtement est enroulé sous la forme d'un rouleau.
A coating according to the invention may include one or more of the following optional characteristics:
  • the grid comprises a network of lower beads in contact with the lower sheet, said lower beads being arranged so as to form lower flow corridors;
  • the mesh comprises a network of upper beads in contact with the upper sheet and covering the network of lower beads, said upper beads being arranged to form upper flow corridors;
  • the meshes of the mesh are formed by the interlacing of the upper beads and the bottom beads;

  • the lower beads and / or the upper beads have a height, measured in the direction of the thickness of the coating, greater than 1 mm, preferably greater than 1.5 mm and / or less than 4 mm, preferably less than 3 mm;
  • the mesh is fixed to the lower sheet and to the upper sheet by gluing points spaced apart from each other by more than 1 cm, preferably by more than 2 cm, preferably by more than 3 cm and / or by less than 5 cm , preferably less than 4 cm;

DéfinitionsDefinitions

La direction de l'épaisseur est la direction de la plus petite dimension du revêtement. Elle est donc perpendiculaire au sol lorsque ledit revêtement est dans sa position de service, c'est-à-dire positionné sur un sol sensiblement plat et de manière à recevoir la pluie.The thickness direction is the direction of the smallest dimension of the coating. It is therefore perpendicular to the ground when said coating is in its service position, that is to say positioned on a substantially flat ground and so as to receive rain.

Une feuille est dite « perméable » lorsque, dans sa position de service, elle peut être traversée par l'eau de pluie qui tombe sur le revêtement.A sheet is said to be “permeable” when, in its service position, it can be crossed by rainwater which falls on the covering.

Les verbes « comporter », « comprendre » et « présenter » doivent être interprétés de manière non exclusive.The verbs "behave", "understand" and "present" must be interpreted in a non-exclusive manner.

Description détailléedetailed description

Les figures 1 et 2 montrent un revêtement 10 de gazon artificiel selon l'invention recouvrant le sol G. Le revêtement comprend une couche de gazon artificiel 12 recouvrant une nappe de support 14 formant un tampon entre le sol et la couche de gazon.The Figures 1 and 2 show a covering 10 of artificial grass according to the invention covering the ground G. The covering comprises a layer of artificial grass 12 covering a support ply 14 forming a buffer between the ground and the layer of grass.

De préférence, au moins la nappe de support, de préférence le revêtement est suffisamment souple pour former un rouleau. Il est donc particulièrement avantageux que la couche de gazon artificiel et la nappe de support soient suffisamment flexibles pour permettre un tel enroulement sans se détériorer. Ainsi, il est particulièrement simple de déplacer le revêtement.Preferably, at least the support ply, preferably the covering is flexible enough to form a roll. It is therefore particularly advantageous that the artificial grass layer and the support ply are sufficiently flexible to allow such a winding without deteriorating. It is therefore particularly easy to move the covering.

Préférentiellement, la couche de gazon artificiel est disposée de manière amovible sur la nappe de support. Ainsi, il est possible de déplacer ces deux parties du revêtement indépendamment l'une de l'autre.Preferably, the artificial turf layer is removably arranged on the support ply. Thus, it is possible to move these two parts of the coating independently of one another.

La couche de gazon artificiel est formée d'un substrat 16 en contact avec la nappe de support 14 et sur lequel sont fixés des brins 18 formant des brins d'herbe artificielle, préférentiellement en matériau polymère, de préférence en plastique, préférentiellement traités pour résister aux ultraviolets.The artificial turf layer is formed of a substrate 16 in contact with the support ply 14 and on which are strands 18 forming blades of artificial grass, preferably made of polymer material, preferably plastic, preferably treated to resist ultraviolet.

La couche de gazon artificiel comprend de préférence des brins en polyéthylène, préférentiellement sensiblement rectiligne, des brins en polypropylène, préférentiellement frisés, et/ou des brins en polyamide. La hauteur totale de cette couche peut être supérieure à 20 mm, de préférence supérieure à 30 mm et/ou inférieure à 50 mm, de préférence inférieure à 40 mm. La masse surfacique de cette couche peut être supérieure à 1000 g/m2, de préférence supérieure à 1500 g/m2 et/ou inférieure à 2500 g/m2, de préférence inférieure à 2000 g/m2.The layer of artificial grass preferably comprises strands of polyethylene, preferably substantially straight, strands of polypropylene, preferably crimped, and / or strands of polyamide. The total height of this layer may be greater than 20 mm, preferably greater than 30 mm and / or less than 50 mm, preferably less than 40 mm. The surface mass of this layer can be greater than 1000 g / m 2 , preferably greater than 1500 g / m 2 and / or less than 2500 g / m 2 , preferably less than 2000 g / m 2 .

De préférence, le substrat est traversé suivant la direction de l'épaisseur du substrat par des trous de drainage 15. Avantageusement, ces trous de drainage permettent à l'eau de pluie de traverser la couche de gazon artificiel 12 et d'atteindre le support 14.Preferably, the substrate is crossed in the direction of the thickness of the substrate by drainage holes 15. Advantageously, these drainage holes allow rainwater to pass through the layer of artificial grass 12 and reach the support. 14.

Dans un mode de réalisation préféré, le substrat est formé, selon la direction de l'épaisseur du substrat, d'une feuille d'appui primaire, de préférence en un matériau polymère, de préférence en plastique, de préférence en polypropylène, de préférence en polypropylène traité pour résister aux ultraviolets, de préférence recouverte d'un revêtement en latex, sur laquelle les brins 18 sont tissés, et d'une feuille d'appui secondaire, de préférence en matériau polymère, de préférence en polyuréthane et/ou en polypropylène, de préférence traitée pour résister aux ultraviolets, de préférence recouverte d'un revêtement en latex. La hauteur du substrat peut être supérieure à 1 mm, de préférence supérieure à 1,5 mm, et/ou inférieure à 4 mm, de préférence inférieure à 3 mm.In a preferred embodiment, the substrate is formed, in the direction of the thickness of the substrate, of a primary backing sheet, preferably made of a polymer material, preferably plastic, preferably polypropylene, preferably made of polypropylene treated to resist ultraviolet rays, preferably covered with a latex coating, on which the strands 18 are woven, and with a secondary backing sheet, preferably made of polymer material, preferably made of polyurethane and / or polypropylene, preferably treated to resist ultraviolet, preferably covered with a latex coating. The height of the substrate can be greater than 1 mm, preferably greater than 1.5 mm, and / or less than 4 mm, preferably less than 3 mm.

De préférence, la nappe de support comprend, de préférence est constituée de, selon la direction de l'épaisseur de la nappe, une feuille inférieure 20 en contact avec le sol, une feuille supérieure 22 perméable à l'eau de pluie en contact avec la couche de gazon artificiel 12, et un grillage 24 perméable à l'eau de pluie interposé entre lesdites feuilles.Preferably, the support ply comprises, preferably consists of, in the direction of the thickness of the ply, a lower sheet 20 in contact with the ground, an upper sheet 22 permeable to rainwater in contact with the layer of artificial grass 12, and a mesh 24 permeable to rain water interposed between said sheets.

Dans un mode de réalisation préféré, les feuilles sont fixées au grillage par collage. De préférence les feuilles sont fixées au niveau de points de collage 25 espacés les uns des autres d'au moins 1 cm, préférentiellement d'au moins 2 cm, préférentiellement d'au moins 3 cm et/ou de moins de 5 cm, préférentiellement de moins de 4 cm. Avantageusement, le positionnement des points de collage permet de fixer le grillage aux feuilles tout en permettant au revêtement de conserver une flexibilité suffisante pour être facilement enroulé ou plié. De préférence, les points de collage sont aux coins des mailles du grillage. Tous les moyens permettant la fixation des feuilles sont cependant envisageables.In a preferred embodiment, the sheets are attached to the mesh by gluing. Preferably the sheets are fixed at gluing points 25 apart from each other at least 1 cm, preferably at least 2 cm, preferably at least 3 cm and / or less than 5 cm, preferably less than 4 cm. Advantageously, the positioning of the bonding points makes it possible to fix the mesh to the sheets while allowing the covering to retain sufficient flexibility to be easily rolled up or folded. Preferably, the bonding points are at the corners of the mesh of the mesh. All the means for fixing the sheets are however possible.

Dans un mode de réalisation préféré, la feuille inférieure est perméable à l'eau de pluie. Ainsi, l'eau de pluie peut traverser le revêtement et atteindre le sol. Cet agencement est particulièrement avantageux lorsque le sol sur lequel le revêtement est placé peut absorber l'eau de pluie, par exemple lorsque le revêtement est situé sur de la terre ou sur du sable.In a preferred embodiment, the bottom sheet is permeable to rainwater. Thus, rainwater can pass through the coating and reach the ground. This arrangement is particularly advantageous when the ground on which the covering is placed can absorb rainwater, for example when the covering is situated on earth or on sand.

Toutes les feuilles perméables connues pour former une barrière empêchant la pousse des végétaux peuvent être utilisées pour la feuille inférieure 20.

Avantageusement, la feuille supérieure forme ainsi un filtre permettant de retenir efficacement des déchets et des particules macrométriques. Cette feuille peut être en particulier mise en forme par calandrage ou par un procédé de cuisson.All the permeable sheets and making it possible to limit clogging of the mesh can be used for the upper sheet 22. Preferably, the upper sheet 22 comprises a nonwoven, preferably treated to resist ultraviolet rays, made up of intertwined fibers, preferably made of a material polymer, preferably plastic, preferably polypropylene.

This sheet can in particular be shaped by calendering or by a cooking process.

Dans un mode de réalisation préféré, le grillage est constitué d'un ensemble de mailles 34, de préférence de forme générale en losange, de préférence régulièrement réparties, de préférence en un matériau polymère, de préférence en plastique, de préférence en polyéthylène de haute densité. La masse surfacique de ce grillage peut être supérieure à 300 g/m2, de préférence supérieure à 400 g/m2 et/ou inférieure à 800 g/m2, de préférence inférieure à 600 g/m2.In a preferred embodiment, the mesh consists of a set of meshes 34, preferably of general diamond shape, preferably regularly distributed, preferably of a polymer material, preferably of plastic, preferably of high polyethylene. density. The surface mass of this mesh may be greater than 300 g / m 2 , preferably greater than 400 g / m 2 and / or less than 800 g / m 2 , preferably less than 600 g / m 2 .

De préférence, chaque maille 34 se présente sous la forme d'un losange dont la plus grande diagonale 36 mesure plus de 1 cm, préférentiellement plus de 2 cm et/ou moins de 5 cm, préférentiellement moins de 4 cm et dont la plus petite diagonale 38 mesure au moins 0,5 cm, préférentiellement au moins 1 cm, et/ou moins de 3 cm, préférentiellement moins de 2 cm.Preferably, each mesh 34 is in the form of a diamond, the largest diagonal 36 of which measures more than 1 cm, preferably more than 2 cm and / or less than 5 cm, preferably less than 4 cm and of which the smallest diagonal 38 measures at least 0.5 cm, preferably at least 1 cm, and / or less than 3 cm, preferably less than 2 cm.

Le grillage est de préférence constitué par :

  • un réseau inférieur de bourrelets inférieurs 26, de préférence sensiblement rectilignes, s'étendant de préférence sensiblement parallèlement les uns aux autres selon une direction inférieure Δ26, et de préférence s'étendant, dans la position de service, dans un même plan inférieur P26; et
  • un réseau supérieur de bourrelets supérieurs 30, de préférence sensiblement rectilignes, s'étendant de préférence sensiblement parallèlement les uns aux autres selon une direction supérieure Δ30, différente de la direction inférieure Δ26, et de préférence s'étendant, dans la position de service, dans un même plan supérieur P30.
The mesh is preferably made up of:
  • a lower network of lower beads 26, preferably substantially rectilinear, preferably extending substantially parallel to each other in a lower direction Δ 26 , and preferably extending, in the service position, in the same lower plane P 26 ; and
  • an upper network of upper beads 30, preferably substantially rectilinear, preferably extending substantially parallel to each other in an upper direction Δ 30 , different from the lower direction Δ 26 , and preferably extending, in the position of service, in the same upper plane P 30 .

Préférentiellement, la masse surfacique d'un réseau de bourrelets est supérieure à 100 g/m2, de préférence supérieure à 200 g/m2 et/ou inférieure à 400 g/m2, de préférence inférieure à 300 g/m2. De préférence, le réseau de bourrelets inférieurs et le réseau de bourrelets supérieurs ont la même masse surfacique.Preferably, the surface mass of a network of beads is greater than 100 g / m 2 , preferably greater than 200 g / m 2 and / or less than 400 g / m 2 , preferably less than 300 g / m 2 . Preferably, the network of lower beads and the network of upper beads have the same basis weight.

Les réseaux supérieur et inférieur sont superposés l'un à l'autre. Vu de face, les réseaux supérieur et inférieur définissent ainsi les mailles en forme de losange, les bourrelets inférieurs étant fixés aux bourrelets supérieurs aux coins des losanges.The upper and lower networks are superimposed on each other. Seen from the front, the upper and lower networks thus define the diamond-shaped meshes, the lower beads being fixed to the upper beads at the corners of the diamonds.

Comme représenté sur les figures 3 et 4, le réseau inférieur forme des couloirs d'écoulement inférieurs 28, chaque couloir d'écoulement inférieur 28 étant délimité latéralement par deux bourrelets inférieurs 26 adjacents. Ces couloirs permettent d'entrainer l'eau de pluie vers deux premiers bords extérieurs du grillage opposés. Avantageusement, l'écoulement n'est pas entravé par les bourrelets supérieurs, au moins tant que la hauteur de l'eau ne dépasse pas la hauteur des bourrelets inférieurs.As shown on figures 3 and 4 , the lower network forms lower flow corridors 28, each lower flow corridor 28 being delimited laterally by two adjacent lower beads 26. These corridors allow rainwater to be drawn towards the first two outer edges of the opposite mesh. Advantageously, the flow is not hampered by the upper beads, at least as long as the height of the water does not exceed the height of the lower beads.

De préférence, les bourrelets inférieurs présentent une hauteur (mesurée selon la direction de l'épaisseur du revêtement) et/ou une largeur supérieure à 1 mm, de préférence supérieure à 1,5 mm, et/ou inférieure à 4 mm, de préférence inférieure à 3 mm.Preferably, the lower beads have a height (measured in the direction of the thickness of the coating) and / or a width greater than 1 mm, preferably greater than 1.5 mm, and / or less than 4 mm, preferably less than 3 mm.

De préférence, la distance entre deux bourrelets inférieurs adjacents quelconques est supérieure à 0,5 cm, de préférence supérieure à 1 cm et/ou inférieure à 4 cm, de préférence inférieure à 2 cm.Preferably, the distance between any two adjacent lower beads is greater than 0.5 cm, preferably greater than 1 cm and / or less than 4 cm, preferably less than 2 cm.

De préférence, les bourrelets inférieurs sont fixés aux bourrelets supérieurs par fusion locale de matière. De préférence, tous les bourrelets sont en un même matériau. Le grillage peut être en particulier fabriqué par extrusion. Tous les procédés de fabrication de grillages monoblocs en matériau polymère sont envisageables.Preferably, the lower beads are fixed to the upper beads by local melting of material. Preferably, all the beads are made of the same material. The mesh can in particular be produced by extrusion. All the methods for manufacturing one-piece fences made of polymer material can be envisaged.

Comme représenté sur la figure 3, le réseau supérieur forme des couloirs d'écoulement supérieurs 32, chaque couloir d'écoulement supérieur 32 étant délimité latéralement par deux bourrelets supérieurs 30 adjacents. Ces couloirs permettent d'entrainer l'eau de pluie vers deux deuxièmes bords extérieurs du grillage opposés une fois que la hauteur de l'eau a dépassé la hauteur des bourrelets inférieurs. Ces deux bords extérieurs sont, de préférence, différents des deux bords extérieurs vers lesquels les couloirs d'écoulement inférieurs débouchent.As shown in the figure 3 , the upper network forms upper flow corridors 32, each upper flow corridor 32 being delimited laterally by two adjacent upper beads 30. These corridors make it possible to entrain rainwater towards two second external edges of the opposite mesh once the height of the water has exceeded the height of the lower beads. These two outer edges are preferably different from the two outer edges to which the lower flow corridors open.

Avantageusement, la présence d'un réseau de bourrelets supérieurs permet d'accélérer le drainage de l'eau lorsque la hauteur de l'eau dépasse le réseau de bourrelets inférieurs 26. Ainsi, il est possible d'augmenter considérablement le drainage en présence d'une grande quantité d'eau, par exemple lors de pluie forte.Advantageously, the presence of a network of upper beads makes it possible to accelerate the drainage of water when the height of the water exceeds the network of lower beads 26. Thus, it is possible to considerably increase the drainage in the presence of '' a large amount of water, for example during heavy rain.

Le grillage assure ainsi un drainage à deux vitesses. En cas de pluie faible, l'eau est principalement drainée par les couloirs d'écoulement inférieurs, vers deux premiers bords du revêtement. En cas de pluie forte, de l'eau est en outre drainée par les couloirs d'écoulement supérieurs, vers deux deuxièmes bords du revêtement.The mesh thus ensures two-speed drainage. In the event of light rain, the water is mainly drained through the lower drainage corridors, towards the first two edges of the covering. In the event of heavy rain, water is also drained through the upper drainage corridors, towards two second edges of the covering.

De préférence, les bourrelets supérieurs présentent une hauteur (mesurée selon la direction de l'épaisseur du revêtement) et/ou une largeur supérieure à 1 mm, de préférence supérieure à 1,5 mm, et/ou inférieure à 4 mm, de préférence inférieure à 3 mm.Preferably, the upper beads have a height (measured in the direction of the thickness of the coating) and / or a width greater than 1 mm, preferably greater than 1.5 mm, and / or less than 4 mm, preferably less than 3 mm.

De préférence, la distance entre deux bourrelets supérieurs adjacents quelconques est supérieure à 0,5 cm, de préférence supérieure à 1 cm et/ou inférieure à 4 cm, de préférence inférieure à 2 cm.Preferably, the distance between any two adjacent upper beads is greater than 0.5 cm, preferably greater than 1 cm and / or less than 4 cm, preferably less than 2 cm.

De préférence, la distance entre deux bourrelets supérieurs adjacents quelconques est identique à la distance entre deux bourrelets inférieurs adjacents quelconques.Preferably, the distance between any two adjacent upper beads is identical to the distance between any two adjacent lower beads.

Préférentiellement, lorsque la feuille supérieure et la feuille inférieure sont fixées au grillage par l'intermédiaire de points de collage 25, ces points sont situés au niveau de points où un bourrelet supérieur 30 est en contact avec un bourrelet inférieur 26. Le risque de décollement en est réduit. Par ailleurs, le collage par point peut avantageusement autoriser un écoulement entre une feuille et un bourrelet du grillage en contact avec la feuille.Preferably, when the upper sheet and the lower sheet are fixed to the grid by means of gluing points 25, these points are located at points where an upper bead 30 is in contact with a lower bead 26. The risk of detachment is reduced. Furthermore, point bonding can advantageously allow flow between a sheet and a bead of the mesh in contact with the sheet.

L'invention n'est pas limitée aux modes décrits. En particulier, le grillage peut comprendre plus de deux réseaux de bourrelets. En outre, toute forme de maille est envisageable sans pour autant s'écarter de la portée de la présente demande.The invention is not limited to the modes described. In particular, the mesh may include more than two arrays of beads. In addition, any form of mesh is possible without departing from the scope of the present application.

Dans le cadre de l'invention, il est aussi envisageable que le revêtement comprenne plus d'une feuille inférieure et/ou plus d'une feuille supérieure. Il est aussi possible qu'une ou plusieurs couches ou feuilles intermédiaires soient situées entre le grillage et la feuille supérieure, entre le grillage et la feuille inférieure et/ou entre la feuille supérieure et la couche de gazon artificiel. En outre, la feuille inférieure et/ou la feuille supérieure peuvent comprendre ou être constituées d'une toile de textile tissé, préférentiellement traité pour résister aux ultraviolets, constitué de fibres tissées, de préférence en un matériau polymère, de préférence en plastique, de préférence en polypropylène.In the context of the invention, it is also conceivable that the coating comprises more than one lower sheet and / or more than one upper sheet. It is also possible that one or more layers or intermediate sheets are located between the mesh and the top sheet, between the mesh and the bottom sheet and / or between the top sheet and the layer of artificial grass. In addition, the lower sheet and / or the upper sheet may comprise or consist of a woven textile fabric, preferably treated to resist ultraviolet rays, consisting of woven fibers, preferably made of a polymer material, preferably plastic, preferably polypropylene.
