The Pros and Cons of Site Cast and Precast Retaining Walls

If you are working on the construction of a commercial building, some of the things that you will be dealing with are walls. You will need retaining walls for sloping or uneven areas with soil that you need to retain. There are two options for these retaining walls. You can go for a site cast or precast retaining wall. Site cast or also called in-situ is a concrete wall that is made on site. Precast, on the other hand, is pre-made at the manufacturer’s site and transported to the construction area. Both of these choices have their pros and cons, which we listed below.

Precast Pros

  • Low-cost. Precast walls are mass-produced. Since there is less labour, the cost is also lower. They are also available at a specific price, so you know right away if they fall within your budget or how much they will cost you.
  • Variety of options. There are different types of precast walls available, so you can easily find one that will fit your needs. Some of them are modular, bolt down, and cast in retaining walls.
  • Quality controlled. The manufacturing company follows a standard in making the precast walls. They also undergo quality checks, so you can be sure that they are up to the business standard, and they are ready to be used for your construction.
  • Environment-friendly. The preciseness in making these concrete walls in the factory is high, which is why very little material goes to waste, making it good for the environment.
  • Makes construction quicker. The workers on the construction site can immediately work on the installation of these walls, instead of having to do them on site.

Precast Cons

  • Longer travel. Since they are built off-site, they need to be transported from the factory to the construction site. This makes them more susceptible to the risk of being damaged.
  • Needs careful planning. It would be hard to modify a precast wall, so you need to make sure that they all fit perfectly on the site.

Site Cast Pros

  • Minimal move. The concrete walls are made on-site, so the movement is minimal. It lessens the risk of the walls being damaged.
  • You can easily customize them specifically to your needs. Modification is more convenient as you can see the actual progress and situation of the construction site as you make them.
  • They are durable as they do not have gaps that precast walls have. Also, you can request them to be stronger than the standard to ensure that they will hold.

Site Cast Cons

  • More expensive. You will be paying extra for the labour, so you will spend more if having the walls made on site.
  • Requires time and effort. Your men will work on building these walls, which will require their time and effort. They will go straight to the installation if they use precast concrete walls.

Weigh up the pros and cons of site-cast and precast concrete retaining walls. Every construction project is unique, so see which of these two options best fits your specific needs.
