High-Performance Sprayed Concrete Solutions

Allied Concrete supplies Shotcrete, a high-performance concrete solution that is sprayed into place rather than cast using traditional formwork. Shotcrete offers superior durability, adhesion, and flexibility, making it ideal for complex structural applications, complex reinforced concrete geometrical shapes, tunnelling, and slope stabilisation. 

Wet Spray Process 

• Uses pre-mixed ready-mix concrete 

• Compressed air and admixtures are introduced at the nozzle to spray the mix onto the surface 

• Provides higher production rates and reduced dust generation 

• Ideal for large-scale structural applications and commercial projects 

Key Benefits of Shotcrete 

• Fast Application – Reduces formwork needs, accelerating project timelines 

• High Strength & Durability – Excellent bonding properties and long-term structural integrity 

• Adaptability – Suitable for curved, vertical, and overhead applications 

• Reinforcement Options – Compatible with steel, synthetic, and fibres for enhanced performance 

Common Applications 

• Tunnels and underground structures 

• Slope stabilisation and retaining walls 

• Swimming pools and water features 

• Bridge and infrastructure repairs 

• Seismic strengthening and foundation reinforcement 

Enhanced Performance with Admixtures 

Shotcrete can be tailored with specialised admixtures to improve performance: 

• Microsilica compounds & fly ash – Reduces rebound loss and enhances durability and can assist in sustainability credentials of the concrete.

• Set accelerators – Speeds up curing, commonly used in dry spray applications 

• Retarders – Extends workability for up to 24 hours, beneficial for mining and tunnelling 

Quality Control & Certification 

Ensuring high-quality shotcrete depends on the mix design, application technique, and skilled nozzle operators applying the product. Allied Concrete follows strict batching procedures to maintain performance consistency. 

• Testing & Quality Assurance – Shotcrete is tested using approved mix design data and batching records rather than traditional cylinder samples. 

• Nozzleman Certification – Ensure employment of suitably qualified nozzle operators when applying shotcrete to ensure high-quality outcomes.
