Rocky Shotcrete Machines South Africa | High-Performance Wet & Dry Shotcrete Pumps
High-Performance Shotcrete Pumps and Mixers Built for South African Mines
The Rocky Range delivers reliable wet and dry shotcrete performance for underground mining, tunnelling, and support work. Every machine is engineered to handle abrasive mixes, challenging headings, and continuous production demands. The design focuses on consistent output, simple maintenance, and long service life.
The range covers wet shotcrete pumps, diesel units for remote sites, and electric machines for fixed installation.
Why Mines Choose Rocky Machines
You get a machine that delivers stable output, predictable spray quality, and low operating cost. Mines using Rocky units report:
- Reduced downtime due to simple rotor-stator assemblies
- Lower wear costs compared to competing pumps
- Improved operator control during spraying
- Reliable performance in high humidity and dust
Our wet shotcrete pumps work with underground accelerators and high-strength mixes used across the Western, Northern, and Eastern Limb mining areas.
