Shotcrete service is a pneumatic concrete spraying process that nearly eliminates the need for formwork. This allows construction to move much faster than traditional concrete pouring methods, as well as reduces labor hours, leading to direct construction costs savings. This method can also create stronger, more durable concrete than conventional methods because it’s applied at such a high impact velocity.
While there are some drawbacks to using this commercial shotcrete service construction method, it’s still an excellent choice for many different jobs. The best commercial shotcrete contractors understand how to apply this construction material correctly, and can make sure that it’s the right option for your project. The following are some of the key reasons to choose this type of concrete application:
This method is ideal for construction and repairs that would be difficult, or not possible with traditional concrete. It can be used in difficult-to-reach areas that would otherwise require expensive and time-consuming crane work, and it’s even suitable for underground or overhead applications. It is highly adaptable, making it a great option for repairing existing structures, as well as for new construction projects that wouldn’t be cost-effective with other concrete methods.
It’s easier to apply than other construction materials. Shotcrete is sprayed onto the surface through a delivery system that includes a pump and hose, which gives construction professionals full control over the application of the concrete mix. This allows for a very precise placement of the concrete, and it can be shaped to fit into tight spaces.
With this concrete construction method, it’s possible to save up to 50% of the time that would be spent preparing the area for traditional concrete pouring. This is because you don’t need to wait for the concrete to hydrate and set, which can slow down your construction schedule significantly. In addition, you can reduce the amount of time that your crew spends setting up and tearing down forms, which helps to further cut down on labor costs.
There are two types of shotcrete — dry and wet. Both methods utilize compressed air to spray concrete, but the wet process mixes all ingredients, including water, before introducing them into the delivery hose. The nozzle is then modified by a skilled nozzleman, and the concrete is sprayed on the planned surface at a very high impact velocity.
Wet shotcrete is a great option for swimming pools, as it’s a monolithic pool shell that doesn’t have any cold joints and is extremely long-lasting. This type of pool can be customized with various surface finishes and features, such as natural or faux rock waterfalls, concrete “shot” or “faux” rock grottoes, fire pits, fountains and more.
The wet shotcrete process is also used for a variety of other applications, such as slope pavement and soil nailing. It’s an excellent choice for slope stabilization, because it can be sprayed on steep surfaces to anchor reinforcement bars that stabilize the surface. This prevents the loose material from falling down the slope and can reduce erosion and the risk of landslides.
