Paver

A paver is a paving unit used to create hard surfaces for outdoor areas such as driveways, patios, walkways, and roads. Pavers are typically made of concrete, clay brick, natural stone, or composite materials. They come in various shapes, including rectangular slabs, square bricks, and interlocking profiles, allowing flexible patterns and textures. A related term, asphalt paver, refers to a machine that lays asphalt pavement, while the term paver can also describe a person who lays paving stones as a trade profession.

Materials and types: Concrete pavers are common and durable; brick pavers offer a traditional look; natural stone pavers include granite, limestone, and sandstone; permeable pavers allow water infiltration and are used for stormwater management. Pavers are often installed in a raised sand setting or set in mortar, depending on the application. Interlocking designs improve stability.

Installation: Base preparation is critical: a compacted subgrade, a granular base, and a bedding layer. Pavers are laid in the chosen pattern with tight joints and then edged with restraints to prevent movement. Jointing sand is swept into the joints and compacted; final compaction settles the surface and seals the joints.

Maintenance: Regular cleaning and weed control extend life. Re-sanding joints may be necessary after maintenance. Sealing pavers can enhance color and stain resistance in some applications.

Durability and sustainability: Pavers are modular and repairable; individual units can be replaced if damaged. Permeable pavers reduce runoff and can contribute to stormwater management while meeting local codes.
