What Is Shotcrete And Why Is It Used For Concrete Pools?

If you are researching pool building options, you have probably come across the term “shotcrete.” It is one of the most important components in building a high-quality concrete pool, yet many homeowners are not entirely sure what it means or why it matters.

Understanding shotcrete can give you a clearer picture of how your pool will be built, how durable it will be, and why concrete pools are often considered the premium choice—especially for custom designs.

At JKO Pool Construction, we use shotcrete to build strong, long-lasting pools that are tailored to each client’s space and vision. In this article, we will break down what shotcrete is, why it is used, and how it compares to other pool construction methods.

What Is Shotcrete?

Shotcrete is a method of applying concrete using a high-pressure hose. Instead of pouring concrete into forms like traditional construction, shotcrete is sprayed onto a reinforced steel framework (also known as rebar).

This process allows the concrete to be applied with precision, forming the exact shape and structure of the pool.

There are two main types of shotcrete:

• Dry-mix shotcrete – where dry concrete materials are mixed with water at the nozzle during application
• Wet-mix shotcrete (often called gunite) – where the concrete is pre-mixed with water before being sprayed

Both methods achieve similar results, creating a dense, durable concrete shell that forms the foundation of the pool.

Why Is Shotcrete Used For Concrete Pools?

Shotcrete is widely used in concrete pool construction because it offers flexibility, strength, and reliability. Unlike pre-moulded pool options, it allows for complete customisation while still delivering a structurally sound result.

Here are the main reasons why shotcrete is used:

It Allows For Custom Pool Shapes

One of the biggest advantages of shotcrete is that it can be applied to almost any shape. Because it is sprayed onto a steel framework, the pool can be designed to suit your exact backyard layout.

This is especially useful for:

• Sloping blocks
• Narrow or irregular spaces
• Custom features like steps, ledges, and seating
• Unique shapes that cannot be achieved with fibreglass pools

For homeowners who want a pool tailored to their space, shotcrete is the key to making that possible.

It Creates A Strong Structural Shell

Shotcrete forms a solid, reinforced concrete shell that is incredibly strong. When applied correctly, it bonds tightly around the steel reinforcement, creating a structure that can withstand ground movement, pressure, and long-term use.

This strength is one of the main reasons concrete pools are known for their durability.

It Provides Long-Term Reliability

A properly built shotcrete pool can last for decades. Unlike some other pool types that may be more prone to cracking or warping over time, shotcrete offers long-term structural integrity.

With the right maintenance and surface finishes, a concrete pool built with shotcrete can continue to perform and look great for many years.

Strength And Durability Of Shotcrete Pools

When it comes to pool construction, strength is everything. Your pool is constantly exposed to water pressure, soil movement, and environmental conditions, especially in coastal areas like the Gold Coast.

Shotcrete stands out because it creates a dense and compact concrete structure. The high-pressure application ensures that the material is tightly packed, reducing voids and increasing overall strength.

Key durability benefits include:

• Strong bond with steel reinforcement
• Ability to handle ground movement better than rigid moulded pools
• Long lifespan compared to alternative pool types

This makes shotcrete an ideal choice for homeowners who want a pool that will stand the test of time.

How Shotcrete Compares To Other Pool Construction Methods

To understand the value of shotcrete, it helps to compare it with other common pool construction methods.

Shotcrete Vs Fibreglass Pools

Fibreglass pools are pre-manufactured shells that are delivered and installed in one piece. While they can be quicker to install, they come with limitations.

Key differences:

• Shape limitations – Fibreglass pools come in fixed shapes and sizes, while shotcrete pools are fully custom
• Transport restrictions – Large fibreglass pools can be difficult to transport and install in tight spaces
• Durability – Fibreglass can be more susceptible to surface damage over time

Shotcrete offers more flexibility and a more tailored result, making it ideal for custom projects.

Shotcrete Vs Vinyl Liner Pools

Vinyl liner pools use a flexible liner fitted over a frame. While they are often more affordable upfront, they typically require more maintenance and liner replacements over time.

Key differences:

• Longevity – Vinyl liners need replacing every 5–10 years, while shotcrete pools have a much longer lifespan
• Strength – Shotcrete provides a solid structural shell, while vinyl relies on a frame and liner
• Finish quality – Concrete pools can be finished with tiles, pebble, or plaster for a premium look

For homeowners looking for long-term value and durability, shotcrete is the stronger option.

Why Shotcrete Is Ideal For Custom Pools

Customisation is one of the biggest reasons people choose concrete pools, and shotcrete is what makes that level of design possible.

Because the concrete is sprayed into place, it can be shaped and adjusted on-site. This allows builders to create pools that fit perfectly within the available space while incorporating unique design features.

Shotcrete is ideal for:

• Plunge pools in small backyards
• Narrow lap pools along fence lines
• Pools with built-in seating or sun shelves
• Infinity edges and feature walls
• Complex or irregular designs

If you have a specific vision for your pool, shotcrete gives you the flexibility to bring it to life.

The Shotcrete Pool Construction Process

Understanding how shotcrete is used during construction can help you feel more confident in the process.

A typical shotcrete pool build involves:

1. Excavation – The pool area is dug out to the required shape and depth
2. Steel reinforcement installation – A framework of steel rebar is installed to form the structure
3. Shotcrete application – Concrete is sprayed onto the framework using high pressure
4. Shaping and smoothing – The surface is shaped and finished to match the design
5. Curing – The concrete is left to cure and gain strength
6. Finishing – Tiles, coping, and interior finishes are applied

Each stage plays an important role in ensuring the final pool is strong, functional, and visually appealing.

Is Shotcrete More Expensive?

Shotcrete pools are generally more expensive upfront compared to fibreglass or vinyl options. However, they often provide better long-term value.

This is because:

• They are built to last longer
• They require fewer major replacements over time
• They can increase the value of your property
• They offer complete design flexibility

For many homeowners, the ability to create a custom, high-quality pool that suits their space makes the investment worthwhile.

Why Choosing The Right Pool Builder Matters

While shotcrete is a high-quality construction method, the final result depends heavily on the skill and experience of the builder.

Proper application, correct reinforcement, and attention to detail are essential to ensure the pool performs as expected. Poor workmanship can lead to issues down the track, regardless of the materials used.

That is why it is important to work with a trusted and experienced Gold Coast pool builder who understands the shotcrete process and delivers high-quality results.

Build A Stronger, Custom Pool With Shotcrete

Shotcrete is one of the key reasons concrete pools are considered the premium option for homeowners who want strength, durability, and complete design flexibility.
