Shotcrete vs. Gunite: The Structural Differences You Need to Know for Your Soil Type

Shotcrete vs. Gunite: The Structural Differences You Need to Know for Your Soil Type

Whether shotcrete or gunite is the best option for your pool tends to depend on the soil in your backyard. Shotcrete tends to be more reliable and straightforward for standard yards, but gunite provides flexibility that can work well with certain soil types. As experienced pool builders San Diego homeowners trust, the team at San Diego Pools know choosing the right material starts with understanding your soil. Here are some things you’ll need to consider before settling on a material. 

What’s the Difference between Shotcrete and Gunite?

To find the right type of concrete for your pool, it’s important to understand how both options work. Shotcrete refers to wet premixed concrete that’s sprayed onto your pool surface in one layer. Meanwhile, gunite consists of a dry concrete mix that’s sprayed onto the pool wall alongside a mist of water, and it mixes together to form wet concrete during the application process. 

Is Shotcrete or Gunite Stronger?

If you have a type of highly compacted soil that could benefit from extra-strong concrete, you might want to choose shotcrete. Shotcrete has a higher compressive strength rating than gunite. However, keep in mind shotcrete is more prone to cracking than gunite, so improperly applied shotcrete can be very weak, especially in areas with unstable ground.

How Does Soil Moisture Content Affect Your Choice?

If your soil is unusually wet or dry, gunite is often the preferred choice. The benefit of gunite is that your pool installer controls the moisture level. Instead of having to rely on premixed shotcrete from a factory far away, they can customize your gunite to work with your soil’s moisture levels. 

Here’s what Marcio D. from San Diego had to say about his experience with our team:

“They really know what they are doing, and the final product is very solid. SD Pools was able to finish a beautiful pool, the envy of the neighborhood! :-)”

Which Concrete Type Is Best for Shifting Soil?

If you have soil with sand or other aggregates that cause shifting, you’ll typically need extra reinforcement. Gunite and shotcrete both work well with rebar, but shotcrete is slightly more prone to slumping when applied on uneven or shifting surfaces. Gunite allows for a slower installation with multiple coats, so it also allows pool installers to more easily correct issues due to shifting.
