Flooring is the general term for a permanent covering of a floor, or for the work of installing such a floor covering. Floor covering is a term to generically describe any finish material applied over a floor structure to provide a walking surface. Both terms are used interchangeably but floor covering refers more to loose-laid materials.

Materials almost always classified as floor covering include carpet, area rugs, and resilient flooring such as linoleum or vinyl flooring. Materials commonly called flooring include wood flooring, ceramic tile, stone, terrazzo, and various seamless chemical floor coatings.

Flooring materials

The choice of material for floor covering is affected by factors such as cost, endurance, noise insulation, comfort and cleaning effort. Some types of flooring must not be installed below grade (lower than ground level), and laminate or hardwood should be avoided where there may be moisture or condensation.

The sub-floor may be finished in a way that makes it usable without any extra work, see:

Earthen floor adobe or clay floors
Solid ground floor cement screed or granolithic

Soft coverings

Carpet is a floor covering woven or felted from natural or man-made fibers. Fitted carpet is attached to the floor structure, extends wall-to-wall, and cannot be moved from place to place. An underlay can extend carpet life and improve comfort.

Rugs are also woven or felted from fibers, but are smaller than the room in which they are located, have a finished edge, and usually lie over another finished floor such as wood flooring. Rugs may either be temporarily attached to the flooring below by adhesive tape or other methods to prevent creep, or may be loose-laid.
Wood flooring

Many different species of wood are fabricated into wood flooring in two primary forms: plank and parquet. Hardwoods are typically much more durable than softwoods. Reclaimed lumber has a unique appearance and is green.

Laminate is a floor covering that appears similar to hardwood but is made with a plywood or medium density fiberboard (”MDF”) core with a plastic laminate top layer. Laminate may be more durable than hardwood, but cannot be refinished like hardwood. Laminate flooring is available in many different patterns which can resemble different woods or even ceramic tile. It usually locks or taps together.

Bamboo flooring is a floor manufactured from the bamboo plant and is a type of hardwood flooring, though technically not a wood. Bamboo known to be durable and environmental friendly. It is available in many different patterns, colors, and textures.
Resilient flooring

Resilient flooring is made of material that has some elasticity. It includes many different manufactured products including linoleum, sheet vinyl, vinyl composition tile (VCT), cork (sheet or tile), rubber, and others. Performance surfaces used for dance or athletics are made of either wood or a resilient flooring.
Hard flooring

Ceramic tile includes a wide variety of clay products fired into thin units which are set in beds of mortar or mastic with the joints between tiles grouted. Varieties include quarry tile, porcelain tile, terracotta tile, and others.

Many different natural stones are cut into a variety of sizes, shapes, and thicknesses for use as flooring. Stone flooring is usually set in mortar and grouted similar to ceramic tile. Slate and marble are popular types of stone flooring.

Terrazzo consists of marble or other stone aggregate set in mortar and ground and polished to a smooth surface.

Mosaics consists of many small pieces of stone arranged to form a design or picture and are common in cultural and religious centres.
Seamless chemical flooring

Many different seamless flooring materials are available. These are usually latex, polyester, urethane or epoxy compounds which are applied in liquid form to provide a completely seamless floor covering. These are usually found in wet areas such as laboratories or food processing plants. These may have granular or rubberized particles added to give better traction.
