Since outdoor paving tiles come in an assortment of colors and shapes, they may be arranged in distinctive formal patterns, like brickwork, or installed in a more free-form, natural setting, like flagstone pavers. An assortment of pavers may also be used for driveways, large walkways or as part of landscaped gardens. Types of paving tiles include natural stone, brick, flagstone, concrete or interlocking tiles.
Brick pavers, with their uniform shape, allow the builder to create an endless number of patterns. They can be placed end-to-end in rows, with the bricks perfectly lined up, or with the ends of the bricks lining up with the mid-point of the bricks in the next row. The bricks may also be used to create a herringbone pattern, in which rows of bricks are set at 90-degree angles to the next.
Flagstone pavers are large flat stones that come in various thicknesses. They are made by splitting natural sedimentary rock. Flagstone comes in colors that range from red to brown to white, depending on where they're quarried. Patterns include the random rectangle, which uses rectangles and squares of different sizes and a more random pattern using stones of various sizes and shapes.
For a more uniform look, consider concrete pavers or interlocking pavers that are precast at the factory. Concrete pavers are set farther apart, for use as stepping stones or to allow grass to grow in between them. Interlocking pavers have lips on all sides so they may be laid out precisely. The smaller gaps are filled with sand, then the entire paved area is sealed to protect it. Interlocking pavers are often used in large walkways, driveways and in pool areas.
