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 maneuvered into place; examples include precast beams, and wall panels, floors, roofs, and piles.
Precast wall for industrial building are usually flat but increased in height customised to match the storey height. The load bearing structural walls ranges from 150 to 200mm thickness. The non load bearing walls are usually 100mm to 125mm thickness.
The concept of precast (also known as “prefabricated”) construction includes those buildings where the majority of structural components are standardized and produced in plants in a location away from the building, and then transported to the site for assembly.
As a porous material, concrete can allow water to migrate through it, bringing in harmful chemicals, causing short or long-term issues that require serious attention. Having a reliable waterproofing system is vital to having a durable precast product.
