  • Artificial lawn with hollow grass blades
    Patent number: 6495236
    Abstract: An artificial lawn able to absorb and store quantities of water. The stored water is released only when the lawn is walked upon and is available to improve its sliding properties. The artificial lawn includes blades which are at least partly hollow and can consist of small U-shaped tubes. The small tubes can further have openings in their lateral wall so as possibly to be able to absorb water also from the support layer or from a water-storing layer.
