Precast concrete is a construction product produced by casting concrete in a reusable mold or "form" which is then cured in a controlled environment, transported to the construction site and lifted into place. In contrast, standard concrete is poured into site-specific forms and cured on site. 

Precast stone is distinguished from precast concrete by using a fine aggregate in the mixture, so the final product approaches the appearance of naturally occurring rock or stone.

There are many different types of precast concrete, forming systems for architectural applications, differing in size, function, and cost.  Precast architectural panels are also used to clad all or part of a building facade, they can be free-standing walls used for landscaping, soundproofing as well as security walls and some can be structural elements.  Storm water drainage, water and sewage pipes and tunnels also make use of precast concrete units.
