They are applied by pouring a normal concrete basis, spreading sand on high, and then laying the pavers in the desired pattern. No actual adhesive or retaining methodology is used other than the burden of the paver itself besides edging. Pavers can be used to make roads, driveways, patios, walkways and other outdoor platforms. Pavement, in development, is an outdoor ground or superficial surface covering. Paving materials include asphalt, concrete, stones such as flagstone, cobblestone, and setts, synthetic stone, bricks, tiles, and sometimes wooden.
