Cast-In-Place Concrete, which is also known as site-cast or poured-in-place concrete refers to concrete that is placed directly on a construction site using formwork as opposed to precast concrete which is cast offsite and then brought to a construction site to be assembled.
Cast-in-place concrete is widely used to create foundations, walls, beams, and other structural elements. Construction workers set up forms and place reinforcing bars according to the project’s specifications. Once these forms and reinforcements are positioned, ready-mix concrete is poured or placed into the forms. This process can involve pouring concrete directly from ready-mix trucks, using pump trucks, concrete conveyors, or manually with wheelbarrows. The popularity of cast-in-place concrete stems from its versatility, offering architects and engineers limitless design possibilities. Additionally, certain structural components, such as foundation caissons, spread footings, slabs on grade, and other large or heavy elements, must be cast on-site because they are too cumbersome to transport from a precast facility.
Almost every building foundation is created using at least some element if not entirely cast-in-place concrete. For example, a concrete wall is an element that can be created using cast-in-place concrete.
