Precast allows designers to be innovative and attain design objectives that are not possible through traditional construction techniques. An unlimited number of form liners and admixtures allow precast concrete to have the appearance of a variety of building materials. These include brick, stone and other masonry products, and are much lower cost than traditional building materials. Brick or stone can also be placed in the mold prior to pouring concrete. Once the concrete has cured the material will be cast into the wall, eliminating extensive labor and delays on the job site. By choosing precast early in the design phase, designers can utilize the full benefits of precast concrete.
