Title (EN) DRAINABLE ARTIFICIAL TURF ASSEMBLY
(FR) ENSEMBLE DE GAZON ARTIFICIEL A DRAINAGE
Abstract:
(EN) An artificial turf assembly (110) has a permeable section (112) formed of an upper layer of artificial turf (118) and a lower layer of shock absorbing material (120) positioned below the upper layer. An impermeable layer (114) is positioned below the permeable section (112) for collecting water flowing downward through the permeable section (112). The permeable section (112) is separable from the impermeable layer (114) to form a space for the water flow away from the assembly. The space may be formed by having the permeable section (112) lying on the impermeable layer (114) so that it lifts off the impermeable layer (114) and floats on the water that flows through the permeable section (112). Alternatively, rigid spacing members (128) may be be provided for maintaining space between the permeable (112) and impermeable (114) layers in the absence of water.
(FR) Un ensemble de gazon artificiel (110) possède une partie impermeable (112) constituée d'une couche supérieure de gazon artificiel (118) et d'une couche inférieure de matériau absorbeur de chocs (120) sous-jacent à ladite couche supérieure. Un couche imperméable (114) est placée sous la partie perméable (112) pour recevoir l'eau qui s'écoule à travers la partie perméable (112). La partie perméable (112) peut se séparer de la couche imperméable (114) pour former un espace permettant à l'eau de s'écouler hors de l'ensemble. On peut former cet espace en posant la partie perméable (112) sur la couche imperméable (114) de sorte qu'elle soit soulevée par l'eau qui s'écoule à travers elle et qu'elle flotte là-dessus. Sinon, des éléments d'écartement rigides (128) peuvent servir à maintenir un espace entre les couches perméable (112) et imperméable (114) en l'absence d'eau.
