A synthetic grass assembly for installation on a supporting soil substrate includes a pile fabric with a flexible sheet backing and rows of upstanding synthetic ribbons representing grass blades, extending upwardly from an upper surface of the backing. An infill layer of two distinct graded courses of particulate material is disposed interstitially between the upstanding ribbons upon the upper surface of the backing and of a depth less than the length of the ribbons. A bottom course of intermixed hard sand and resilient rubber granules with substantially identical particle size distribution characteristics is installed upon the backing and a top course exclusively of resilient rubber granules is placed upon the bottom course.

Synthetic grass with resilient granular top surface layer

Safety improvements of airport runways and taxiways are achieved by providing a flexible, water-impermeable surfacing material on a compacted soil base directly adjacent to an edge of airstrip shoulders. A synthetic grass surface is provided on the area beyond the surfacing material so that foreign objects such as loose particles of the airstrip shoulder materials will be driven by jet blasts and run-off across the relatively smooth texture of the surfacing material and will be trapped by the synthetic grass, thereby minimizing foreign object damage to aircraft engines, particularly to those overhanging engines which extend well beyond the existing runway and taxiway shoulders.

Safety improvements for airport runways and taxiways

An airstrip shoulder-bordering surface arrangement for extending the width of existing runway and taxiway shoulders comprising a flexible water-impermeable surfacing material extending laterally of a side edge of an airstrip shoulder, an artificial grass surface adjacent the water-impermeable surfacing material, and an edge-fastening system for securing the surfacing material in position relative to the airstrip shoulder and prevent water migration therebetween, the surfacing material having a relatively smooth top surface.

An artificial grass surface () suited for bordering a runway () of an airfield in order to reduce the presence of birds in the airfield. The artificial grass surface () includes a pile fabric () having a plurality of pile elements () extending from a backing mat () and resembling grass. A water barrier () is provided for preventing water from percolating to the compacted soil surface. An infilled particulate material () is dispersed among the pile elements (). A stabilizer is provided to resist dislodgment of the infilled particulate material () at the edges of the runways by the thrust of jet engines and to keep the particulate material () in the pile elements () when the edges of the runways are vacuumed to remove silt.

Artificial grass for landscaping

A drainage system is provided for a synthetic grass turf assembly having a flexible and water permeable sheet backing for installation on a supporting soil substrate to provide a game playing surface. The draining system of the present invention prevents water from accumulating on the turf surface, which could cause the top-dressing layer to 'float' and be moved by inundation. The draining system of the present invention includes a spacing grid disposed between the backing of the turf. The spacing grid is structured to permit water not only to be drained vertically through the spacing grid, but also to be drained horizontally through the spacing grid to the edges of the field. The spacing grid is made from one or more types of geotextile or plastics material with an adequate flexibility to improve the impact absorption capabilities and resilience of the synthetic grass turf assembly.
