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 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 layer3 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 the 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. |
