<p>The present invention comprises a series of hollow rotationally moulded plastic panels that can be laid over natural terrain, in order to provide a continuous and durable surface for the passage of people and vehicles. The tops of the panels are flat and the undersides of the said panels may be corrugated or studded to provide a flexible form that can be rolled about a drum or wheel. The ends of the panels have holes through which loops may be inserted to connect the panels in a way that allows any panel to rotate up to 360 degrees around the end of any abutting panel.</p> |
