Publication number: 20080175665Abstract: 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.Type: ApplicationFiled: April 17, 2007Publication date: July 24, 2008Applicant: FIELDTURF TARKETT INC.Inventor: Jean Prevost

Patent number: 7306838Abstract: 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.Type: GrantFiled: November 14, 2005Date of Patent: December 11, 2007Assignee: Fieldturf Tarkett Inc.Inventor: Jean Prévost

Patent number: 7300689Abstract: An artificial grass surface (10) suited for bordering a runway (12) of an airfield in order to reduce the presence of birds in the airfield. The artificial grass surface (10) includes a pile fabric (14) having a plurality of pile elements (20) extending from a backing mat (18) and resembling grass. A water barrier (24) is provided for preventing water from percolating to the compacted soil surface. An infilled particulate material (22) is dispersed among the pile elements (20). A stabilizer is provided to resist dislodgment of the infilled particulate material (22) at the edges of the runways by the thrust of jet engines and to keep the particulate material (22) in the pile elements (20) when the edges of the runways are vacuumed to remove silt.Type: GrantFiled: October 11, 2004Date of Patent: November 27, 2007Assignee: Fieldturf Tarkett Inc.Inventor: Jean Prevost

Patent number: 7273642Abstract: A modular synthetic grass turf assembly includes a plurality of synthetic grass units which are transportable, adapted to be laid flat on a field and fit side by side to provide a flat and continuous synthetic grass surface for activities. Each unit includes a flexible base sheet preferably with drainage grooves and bores if it is for outdoor use. A synthetic grass turf with an infill layer of particulate materials disposed interstitially between synthetic grass fibers is superposed on the base sheet to provide a grass surface with a required quality, and be fixed thereto or simply retained in place by the weight of the infill. A number of units may have irregular shapes or can be painted with different colors to illustrate letters, marks or logos. The modular synthetic grass turf assembly is conveniently transported from a storage facility to a site.Type: GrantFiled: June 4, 2003Date of Patent: September 25, 2007Assignee: Fieldturf Tarkett Inc.Inventor: Jean Prevost

Patent number: 6877932Abstract: 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.Type: GrantFiled: July 12, 2002Date of Patent: April 12, 2005Assignee: Fieldturf (IP) Inc.Inventor: Jean Prévost

Publication number: 20050044656Abstract: An apparatus for renovating and/or cleaning a synthetic grass turf, or for other synthetic grass turf treatments according to the present invention, employs a hollow spike roller which rolls on the synthetic grass turf to enable air jets or other fluids to be expelled from a number of hollow spikes penetrating to a depth of the synthetic grass turf. The penetration depth of the hollow spikes, the angle of air jets and the duration of the individual air jets being expelled, are all adjustable or predetermined, such that the apparatus of the present invention can be conveniently used in various applications for treating synthetic grass turfs. The apparatus reduces or eliminates the potential damage to the grass fibers which presents with use of conventional brushes or highly pressurized fluid jets, and thereby provides efficient performance.Type: ApplicationFiled: August 27, 2003Publication date: March 3, 2005Applicant: Fieldturf, Inc.Inventor: Jean Prevost
