Pressure-treated pine roll-out walkways are a lifesaver and work wonderfully over stone, mulch, mud, grass, sand, ice, snow, and just about any other type of ground you can think of. Keep dirt, mud, and grass off the bottom of your shoes or bare feet by placing one of these roll-outs in any area where there is high traffic. Made with pressure-treated pine and doesn’t have any nails, screws, or metal fasteners that will require maintenance.
