Structural Guniting Solutions
Guniting, or dry-mix shotcrete, is a construction technique where a dry mixture of cement and sand is propelled through a nozzle at high velocity, with water added just before application. Operating under high pressure (2–3 kg/cm²), it forms a dense, durable, and highly impermeable layer (56–70 N/mm² strength) ideal for repairing structural concrete, waterproofing, and strengthening aging infrastructures like tunnels and pools.
The Process
Dry materials are fed into a machine and moved by compressed air through a hose to a nozzle, where water is introduced just before application.
Proportioning
A typical mix of cement and sand is 1:3. High velocity ensures maximum compaction and density on the applied surface.
Preparation
Loose or contaminated concrete is removed via sandblasting to ensure maximum adhesion and structural integrity.
Core Applications
- Damaged Concrete Repair
- Corrosion Prevention for Steel
- Slope Stabilization & Tunnels
- Swimming Pools & Tanks
Key Advantages
- Rapid Application Times
- High Structural Strength
- No Formwork Required
- Ideal for Overhead Surfaces
Nozzle Operator Skill: The quality of the final product is heavily dependent on the operator managing the water-cement ratio and pressure to avoid excessive rebound waste.
