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.
A unit for a modular synthetic grass turf assembly comprising a base sheet adapted to be flat on a support surface, and a synthetic grass system laid on top of the base sheet and provided in sections sized to fit on the base sheet, said synthetic grass system including at least a sheet backing, a plurality of synthetic ribbons extending upward there from and an infill layer of particulate material disposed interstitially between said synthetic ribbons on said sheet backing, said unit including a flexible edge border upwardly extending therefrom around a perimeter thereof for retaining the infill layer in the unit, said base sheet having at least one drainage aperture extending there through, wherein the base sheet is capable of being fit side by side with respect to a base sheet of another such adjacent unit to provide a substantially flat and substantially continuous synthetic grass surface, wherein the flexible edge border extends substantially equal to or less than the level of the infill layer.
A unit for a modular synthetic grass turf assembly comprising a base sheet adapted to be laid flat on a support surface, and a synthetic grass system laid on top of the base sheet, said synthetic grass system including at least a sheet backing, a plurality of synthetic ribbons extending upward therefrom and an infill layer of particulate material disposed interstitially between said synthetic ribbons on said sheet backing, said unit comprising flexible edge borders upwardly extending therefrom around a perimeter thereof for retaining said infill layer, said base sheet comprising at least one tile having a plurality of drainage apertures therethrough, said base sheet being adapted to abut a similar base sheet of an adjacent such unit to provide a modular synthetic grass turf assembly having a substantially continuous base sheet layer on said support surface and a substantially continuous synthetic grass system superimposed thereon, wherein the flexible edge border extend substantially equal to or less than the level of the infill layer.
A method for providing a synthetic grass surface using modular synthetic grass units of a modular synthetic grass turf assembly comprising a base sheet adapted to be laid on a support surface, and a synthetic grass system laid on top of the base sheet and provided in sections sized to fit on the base sheet, said synthetic grass system including at least a sheet backing, a plurality of synthetic ribbons extending upward there from and an infill layer of particulate material disposed interstitially between said synthetic ribbons on said sheet backing, said unit including a flexible edge border upwardly extending there from around a perimeter thereof for retaining the infill layer in the unit, said base sheet having at least one drainage aperture extending there through, wherein the base sheet is capable of being fit side by side with respect to a base sheet of another such adjacent unit to provide a substantially flat and substantially continuous synthetic grass surface, wherein the flexible edge border extends substantially equal to or less than the level of the infill layer, the method comprising steps of:
