Precast Concrete Utility Walls & Fences

Precast concrete utility walls are the most steadfast solutions for better construction management due to its remarkable construction perks and durable features!


The Evolution of Substation Security Walls

In old times, substations were constructed away from the residential areas and protected with chain-link fences. By the time, due to the rapid increase in population, these substations found themselves surrounded by residential areas. it was due to an increase in the population, commercial and industrial development.

Well, substations are national assets and need to be protected. Therefore, when residential and industrial units came adjacent to substations they were protected by using colored plastic planks in chain link fences.

Unfortunately, it was a very fragile and vulnerable solution. So, substation located in populated areas started using masonry transitions. Meanwhile, copper became very expensive. So it became difficult to use a huge amount of copper to build fences. Moreover, the theft risk for copper was also increased tremendously.

Then concrete utility walls came into play as the most suitable option to prevent vandalism and theft. So, the substations where generally chain link fences were used got replaced with solid precast concrete fences to achieve maximum security and protection against line of the sight, break-ins, and thieves. Also, concrete walls are the best option to count in to build tall security walls due to their fast installation and ease of construction.

Precast utility walls are the most useful solution for better construction management. These walls are suitable for almost all kinds of construction needs. This is one of the most prominent features of concrete utility walls that make it the first choice for construction projects in the modern age.

With concrete walls, high-quality finishing can be achieved with the simplest modes of workability and in lesser time. It is used for setting dimensions as well as for the better construction of existing walls and stairwell walls.

Precast concrete utility walls are already available in the form of blocks. Therefore, they can be installed quickly. It not only saves time and labor nut money as well. Therefore concrete fences are considered very affordable. And they are much durable than other fencing material that enables them to bear the harshness of time and weather for longer than others.

Besides, concrete utility walls helps to reduce the infrastructural earthworks during construction that improves work ergonomics. For this reason. Precast concrete walls are the best option for office buildings, schools, hospitals, etc.
