A beach mat is disclosed which comprises a first layer (2) secured to a second layer (3). Each layer (2, 3) is manufactured from a flexible polypropylene mesh material, suitably shade cloth with a shade rating of approximately 70%. The perimeters of each layer (2, 3) are secured together with overlapping tape (4) which is sewn into position. When the mat (1) is placed on sand (5) with the first layer (2) downwards, any sand that passes upwards through the lower surface of the first layer (2) is retained between the first layer (2) and the second layer (3). Any sand that falls on the upper surface of the second layer (4) and passes therethrough is also retained between the first layer (2) and second layer (3). Optionally, a third layer (7) manufactured from polyvinylchloride-coated nylon mesh material can be positioned over the second layer (3) and the perimeters of each layer (2, 3, 6) secured together with overlapping tape (4). The upper surface of the third layer (7) can be screen-printed. Any sand that falls on the upper surface of the third layer (7) passes through that layer and also through the second layer (3) to be retained between the first layer (2) and second layer (3). |
