Abstract
A synthetic turf comprises a backing with a plurality of pile filaments secured to the backing and extending upwardly therefrom and filled with particulate fill material. The pile filaments create a grass-like appearance for the playing surface. The fill material comprises a lower ballast layer of gravel residing on the backing and an upper layer of resilient particles above the lower layer. The lower layer of gravel provides weight and stability to hold down the synthetic turf without migrating to the surface. The upper layer provides cushioning and uniform resilience for the synthetic turf.
Claims18
A filled synthetic turf comprising:
- a foundation;
- a backing residing on the foundation;
- a plurality of grass-like pile filaments secured to the backing and extending generally upwardly therefrom;
- and
- a particulate fill material residing on the backing to a desired height, the pile filaments extending above the fill material, the fill material including,
- a first lower layer of gravel located on the backing and a second upper layer of resilient particles, wherein the first lower layer provides weight for holding down the backing and the second upper layer provides resiliency for the synthetic turf.
A filled synthetic turf comprising:
- a foundation;
- a drainage member residing on the foundation;
- a water permeable backing residing on the drainage member;
- a plurality of grass-like pile filaments secured to the backing and extending generally upwardly therefrom;
- and
- a particulate fill material residing on the backing to a desired height, the pile filaments extending above the fill material, the fill material including,
- a first lower layer of gravel located on the backing and a second upper layer of resilient particles, wherein the first lower layer provides weight for holding the backing and the second upper layer provides resiliency for the synthetic turf.
A filled synthetic turf comprising:
- a foundation;
- a backing residing on the foundation;
- a plurality of grass-like pile filaments secured to the backing and extending generally upwardly therefrom;
- and
- a particulate fill material residing on the backing to a desired height, the pile filaments extending above the fill material, the fill material including gravel and resilient particles, wherein the gravel provides weight for holding the backing in place and the resilient particles provide resiliency for the synthetic turf.
A filled synthetic turf comprising:
- a foundation;
- a backing residing on the foundation;
- a plurality of pile filaments secured to the backing and extending generally upwardly therefrom;
- and
- a particulate fill material residing on the backing to a desired height, the pile filaments extending above the fill material, the fill material including,
- a first lower layer of particles having a diameter greater than 2 millimeters located on the backing and a second upper layer of resilient particles, wherein the first lower layer provides weight for holding the backing and the second upper layer provides resiliency for the synthetic turf.
A method of constructing a filled synthetic turf on a foundation, comprising:
- placing a backing on the foundation, a plurality of pile filaments being secured to the backing and extending generally upwardly therefrom;
- and
- filling a particulate fill material on the backing to a desired height, the pile filaments extending above the fill material, the fill material including a first lower layer of gravel located on the backing and a second upper layer of resilient particles, wherein the first lower layer provides weight for holding the backing on the foundation and the second upper layer provides resiliency for the synthetic turf.
A method of constructing a filled synthetic turf on a foundation, comprising:
