ABSTRACT:
A protective winter turf cover is formed with a layered polyethylene laminated sheet with each layer having force striations running at an angle to the edge of the sheet and with the force striations of one layer at an angle to the force striations of the adjacent layer, the resulting turf cover being lightweight, compactly foldable, and substantially impermeable to water. The protective winter turf cover is efficiently held down with a dual apertured washer and x-position of nails therethrough.
