Pre-Cast Concrete Walls – Types, Connections, and Advantages

Pre-Cast Concrete Walls Panels

Precast concrete wall panels are constructed by casting concrete in a reusable wall mold or form which is then cured in a controlled environment, transported to the construction site and lifted into place. The main function of the precast walls is to speed up the construction process.

We discuss about the types, connections, characteristics, and advantages of precast concrete walls.

Types of Precast Concrete Wall

1. Cladding or Curtain Walls

2. Load-bearing Wall

3. Shear Walls

Types of Connections in Precast Concrete Walls

1. Bolted Connections

2. Welded Connections

3. Dowel/Anchor Bolt Connections

Advantages of Precast Concrete Walls

Precast concrete, a highly efficient, practical method of concrete construction makes beautiful buildings possible at a cost that rivals even the most utilitarian industrial building. Understanding some of the benefits of precast concrete will assist designers in evaluating the impact of precast concrete on the environment and the building operation.

Some of the advantages of Precast Concrete Walls-

1. Design-build Efficiency

Precast concrete offers an efficient delivery model for your project; allowing building construction to proceed while the design is developed.

2. Aesthetically Versatile

Precast concrete can take nearly any shape or size, be manufactured in virtually any color and comes in a wide variety of finishes. With precast, you are limited only by your imagination.

3. Environment Resistant

Precast concrete structures provide superior resistance to fires, natural disasters, insects and mold. Like no other building material, its resistance to rain, wind damage, earthquakes, termites and decay provides lower maintenance and insurance costs. It can also withstand many winters of freeze-thaw cycles better than other building materials.

4. Thermal Efficient

Costs associated with heating and cooling can be greatly reduced through concrete’s thermal mass benefits. Reduced peak heating and cooling loads can be achieved because concrete reacts slowly to changes in outside temperature.

5. WI-FI Compatible

With offices increasingly wired for information technology, it is good news that precast buildings do not interfere with radio signals, local Wi-Fi or internet networks. This makes precast the most technology-friendly building material.

6. Reduced Costs

Precast concrete products are manufactured off-site, under roof and are delivered ready to install when needed. This innovative process compresses project schedules, reduces safety concerns, reduces site disruption and reduces overall project costs by requiring fewer trades for construction and fewer people on site.

7. Low Maintenenance

The exterior of a precast concrete structure can be left unpainted without damage from the elements. If painting is desired, repainting is needed only every five to ten years. Precast concrete interiors are less subject to damage and easier to wash.
