If you’ve ever wondered what precast concrete is, you’ve come to the right place. Here, we’ll talk about what precast concrete is and what it’s used for.
What is Precast Concrete?
In it simplest definition, precast concrete is where concrete is cast in a reusable mold which then is placed in a controlled environment to cure. Then, the concrete piece is transported to the construction site and lifted into whatever place it needs to be. This is different from traditional concrete where it is poured and molded on location.
What Projects Typically Use Precast Concrete?
Because the use of precast concrete is so versatile, it’s used in many different building projects. Here is a list of some of the most common construction projects that utilize precast concrete:
Precast concrete is used in many instances to form entire buildings. But in most other cases, the precast concrete is used specifically for building foundations. This is true for both commercial and residential buildings. Precast concrete is notorious for providing moisture-free, energy efficient spaces, making them the ideal component for a building’s foundation
Most cement parking garages are made from precast concrete. The traffic barriers, columns, paving slabs, stairs and veneer are usually all made from it. You’ll find both single-level and multi-level parking garages that make precast concrete their building material of choice.
If you live in an urban area, you’ve likely seen a cement sound wall that’s used as a noise barrier between busy roads and residential communities. Precast concrete is perfect for this endeavor because it’s known to cut noise pollution by up to 50 percent. These walls are then typically customized to fit the communities by changing the color, shape, design or texture.
Bridges are frequently built with the help of precast concrete. There are different pieces of precast concrete that can be found on the deck slabs, beams, caps, arches, girders and much more. Bridge architects like using precast concrete because it can also be customized to blend in with historical surroundings and feel of the area.
One other very common structure you see that’s created with the help of precast concrete is that of retaining walls. A retaining wall may include multiple components like precast modular blocks (PMB), segmental retaining walls (SRW), and mechanically stabilized earth (SME). No matter the elements, they are combined with the help of precast concrete.
