Frequently Asked Questions Regarding Shotcrete Services

July 28, 2022


Despite their surging vogue and worldwide acceptance, shotcrete services are still a relatively new unknown invention. From structural diversity to a vast range of architectural art, shotcrete boasts an unending list of applications. Unfortunately, inexperienced project owners remain ignorant and unaware of the service’s benefits and viability in exceptional circumstances. Every now and then, numerous contractors and project owners approach us with a list of nothing but the most basic questions regarding the subject matter.

As the top-rated providers of shotcrete services, we have deduced from our investigation that this ignorance and lack of fundamental knowledge is a direct result of an utter lack of dependable information. Despite the popular slogan that the internet knows everything, it is surprising to see that the available information regarding this fantastic construction technique is clearly deficient and insufficient. Had the latter not been the case, many project owners would not have missed out on the cost-saving perks of these services.

In light of the apparent lack of adequate information and the number of queries we receive regarding the service, we have compiled a list of the most frequently asked questions regarding shotcrete services. Since not everyone enjoys the privilege of a direct conversation with a concrete contractor, we have decided to make this basic information as accessible as possible through this blog post.

What Is Shotcrete?

Since our aim is to provide basic information regarding shotcrete services, why not start with the most fundamental question? Before we dig into its applications, let us understand what exactly shotcrete encompasses.

In simpler words, shotcrete is an innovative concrete application technique that seeks to overcome the drawbacks of conventional concrete placement methods. In this case, concrete is pneumatically pumped through a hose at a high velocity onto a vertical or an overhead surface. This projection allows for high-end compactness with a low w/cm ratio, reduced permeability, and high cementitious material content.

When it comes to conventional concrete pouring, the placement process is highly ineffective on vertical or overhead surfaces. As you can mentally visualize it, pouring the concrete mixture on an overhead surface and expecting it to remain compact is no less than a challenge. Similarly, applying concrete to irregular shapes or constructing artwork was also a huge problem. Thanks to this innovative jetting method and the resulting compatibility, the aforementioned restrictions are no longer a bother.

What Are The Wet-Mix And Dry-Mix Processes?

Basically, shotcrete services feature two main application processes: the wet-mix and dry-mix methods. The difference between the two is simply the point at which water is added to the rest of the contents (as their names suggest).

  • Wet-mix: In this case, water is added to a mixture of cement, sand, and other ingredients before introducing the mixture into the shotcrete equipment. The mixture is then pumped through a nozzle, where compressed air is added to the mixture before it is shot onto a surface.
  • Dry-mix: As the name suggests, dry ingredients are introduced into a hopper and pneumatically thrust via a hose to the nozzle. Water is then added to the mixture in the nozzle before it is shot at a surface.

The suitability of these methods varies with the unique needs of each project.

Is Shotcrete More Cost-Effective Than Conventional Concrete Placement Methods?

Given the shortcomings of the traditional concrete application methods, it would be safe to say that shotcrete is a fairly more viable alternative in certain circumstances. In contrast to the manual application of concrete on hard-to-reach surfaces, the shooting mechanisms save a lot of time and ultimately reduce the labour costs per hour. Besides the latter, shotcrete does not require vibrations or separate compaction mechanisms, which also saves a lot of expenses.

However, this method does not outcast the conventional concrete pouring method. In fact, the conventional approach is more suitable for specific applications such as when constructing building foundations.

What Are The Applications Of The Shotcrete Method?

This method flaunts several architectural and structural applications:

Architectural applications

  • Crafting artificial rocks for decorative and landscaping needs
  • In the construction of theme parks and zoo exhibits
  • Retaining and rock wall construction
  • Rock carving and artwork

Structural Applications

  • Hard-to-reach and irregular surfaces.
  • Fixing cracks in pools and other structures.
  • Construction of tanks, domes, and tunnels
