Gunite and Shotcrete Machines in UAE

ACE Centro Enterprises supplies and rents high-performance Gunite and Shotcrete machines for wet and dry concrete spraying applications across the UAE and the Middle East.

What is Gunite?

Gunite is a type of sprayed concrete applied at high velocity through a hose, ensuring dense, strong, and well-bonded layers. It is widely used for swimming pools, tunnels, slope stabilization, retaining walls, and structural concrete repair. The process delivers superior compaction and strength compared to traditional poured concrete.

Gunite Methods – Wet and Dry Process

1. Dry Gunite (Dry-Mix Shotcrete)

In the dry gunite process, the dry mix of cement and aggregates is conveyed through a hose using compressed air. Water is added at the nozzle before spraying onto the surface. This method allows precise control of water content, making it ideal for repair work, vertical, or overhead surfaces.

Controlled water addition at the nozzle
Less material wastage when handled by skilled operators
Suitable for small areas and on-site repairs
Generates more dust during operation

2. Wet Gunite (Wet-Mix Shotcrete)

In the wet gunite process, all ingredients – cement, aggregates, water, and admixtures – are mixed before being pumped through the hose. Compressed air is used to project the mixture onto the surface. This method is cleaner and more productive, commonly used for tunnels, large pools, and structural linings.

Uniform and consistent concrete mix
Less dust and rebound compared to dry process
High efficiency for large projects
Requires more cleaning and continuous operation

Gunite vs Shotcrete – Understanding the Difference

The terms Gunite and Shotcrete are often used interchangeably. Technically, “Gunite” refers to the dry-mix method, while “Shotcrete” covers both dry and wet mix processes. Both methods produce high-strength, durable concrete for construction and rehabilitation applications.

Applications of Gunite and Shotcrete

Swimming pool construction and lining
Tunnel and mine linings
Slope protection and stabilization
Concrete structure repair and rehabilitation
Retaining walls and foundation strengthening
