Patent number: 6746752Abstract: 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: February 7, 2003Date of Patent: June 8, 2004Assignee: Fieldturf Holdings Inc.Inventor: Jean Prevost

Publication number: 20020028307Abstract: A synthetic grass surface comprising widely spaced rows of ribbons and the ribbons having a length about twice as long as the spacing between the rows of ribbons. A particulate material is laid on a matrix of the synthetic grass, and the thickness of the particulate material is as least two-thirds the length of the ribbons.Type: ApplicationFiled: November 20, 2001Publication date: March 7, 2002Applicant: Fieldturf Holding Inc.Inventor: Jean Prevost

Patent number: 5958527Abstract: The invention relates to a synthetic grass turf assembly for installation on a supporting soil substrate to provide a game playing surface that combines the feel of natural turf with the wear resistance of synthetic turf. The turf assembly 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. A unique infill layer of multiple 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 base course is first placed upon the top surface of the backing and consists exclusively of hard sand granules. A middle course of intermixed hard sand and resilient rubber granules with relative weight ratio of 3 to 1 is then placed upon the base course. A top course exclusively of resilient rubber granules is then placed upon the middle course.Type: GrantFiled: October 22, 1998Date of Patent: September 28, 1999Assignee: Fieldturf Holdings, Inc.Inventor: Jean Prevost
