Abstract
A mat for use on sand has a lower layer (2) and an upper layer (3). Sand is able to pass through both layers. Sand falling on the upper layer (3) can pass through it and either remain trapped between the two layers or pass through the lower layer (2) to the ground. The perimeters of each layer are preferably sewn together with overlapping tape (4). Suitable materials for the upper layer and lower layer include polypropylene mesh material, particularly shade cloth with a shade rating of approximately 70%. The mat may optionally include a sand-permeable third layer positioned over the upper layer. The third layer may be made from polyvinylchloride-coated nylon mesh material, and may be screen printed.
