What is Precast Concrete? American Precast

2021-8-19  Precast concrete is not made on-site. It’s typically made in a climate-controlled environment by a skilled worker like cast-in-place concrete; precast concrete is poured into a wooden or steel mold with wire mesh or rebar included to add strength. The great thing is, unlike cast-in-place concrete, these molds can be used again and again.
