ABSTRACT:
The synthetic turf has a base made of fabric material from which upwardly projects a mass of entangled, crimped grass-like frayed blades made of polypropylene, nylon or polyester. The blades have a length between 3/8" and 2", a weight from 28 to 60 ounces per square foot and a denier value of about 5400. The method of treating this synthetic turf consists in sandblasting the blades from above the turf at a distance of about 3 to 4 feet with a jet of sand having a pressure of about 80 to 120 pounds per square inch and directed at an angle of about 70.degree. to 80.degree. from the horizontal and in a circular motion. The border strip for an artificial golf practice course comprises a body made of polystyrene, a sheet of polypropylene applied over the body and a synthetic turf covering applied over the sheet of polypropylene. The body is shaped so that the synthetic turf covering form a ball rolling surface inclined or square with respect to a central playing surface. The understructure for an artificial golf course comprises a plurality of platform structures arranged side-by-side in the manner of a checkerboard, these structures establishing nodal points at the junctions of every group of four adjacent platform structures and a lifting jack at each of the nodal points. Bolts connect the corners of adjacent platform structures at each nodal point to a relevant one of the jacks.
