What Is Gunite and Why Is It Used in Swimming Pools?

Gunite is one of the most widely used materials in concrete pool construction. Known for its strength and flexibility, it allows for fully customised pool shapes while providing long-term durability — making it a popular choice for residential pools across South Africa.

Why Is Gunite Used for Pools?

1. Structural Strength

Gunite creates a dense, reinforced structure that can withstand ground movement and long-term use.

2. Design Flexibility

Unlike pre-moulded fibreglass pools, gunite allows for fully customised shapes, sizes and depths.

This makes it ideal for:

  • Sloped or uneven sites
  • Complex designs
  • Feature elements like steps, benches and ledges


3. Long-Term Durability

When properly constructed and maintained, gunite pools can last for decades.

They can also be resurfaced over time, extending their lifespan.

4. Compatibility with Finishes

Gunite pools can be finished with a range of surfaces, including:

  • Marbelite
  • Plaster
  • Tiles


This allows flexibility in both appearance and budget.

What Is Gunite?

Gunite is a dry mix of cement and sand that is sprayed through a high-pressure hose and combined with water at the nozzle.

This process allows the material to be applied directly onto a reinforced steel framework, forming a solid and durable pool shell.

Is Gunite the Right Choice?

Gunite is typically the best option if you:

  • Want a custom-designed pool

  • Have a challenging or sloped site

  • Are planning a long-term investment

  • Want flexibility in finishes and design
