Abstract
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.
