Interlock paving

In building, paving refers to a surface covering or outdoor floor. Paving materials include asphalt, concrete, bricks, tiles, fake stone, flagstone, cobblestone, and setts, as well as occasionally wood. Pavements are utilized on sidewalks, road surfaces, patios, courtyards, etc. in landscape architecture and are considered an element of the hardscape.

An outdoor flooring material often utilized as paving stones, tiles, bricks, or brick-like pieces of concrete is called a paver. Concrete pavers are manufactured in a factory by pouring a mixture of concrete and a coloring agent into a mold with a specific form and letting it cure. They are often positioned on top of a foundation constructed of sand and stone layers that have been crushed. After the pavers are arranged in the proper design, a polymeric sand is used to fill the spaces between them. Except for edging, no actual glue or retaining technique is employed other than the weight of the paver. Roads, driveways, patios, pathways, and other outdoor platforms can all be built with pavers.
