Precast concrete is a construction product that is manufactured off-site using a mold. The concrete is then cured in a controlled environment, often a precast concrete plant. Once cured, it is removed from the mold, and it is prepared to be shipped to the job site where it will be constructed.
Because precast concrete is more easily controlled, the quality and durability is typically much better than cast-in-place concrete. A precast manufacturer is also more likely to receive greater discounts on materials due to the volume of purchases that can be made for multiple projects at a time.
