Wetkret 4 is the ideal shotcrete equipment for underground tunnels thanks to its robust chassis, the Putzmeister low-pulsation double piston concrete pump with a maximum theoretical flow rate of 20 m³/h, the automatic synchronisation of the admixture with the concrete flow rate, and a maximum vertical throw range of 8.5 m, among other things.

Compact, Strong and Versatile to Enhance the Total Concrete Spraying Process in Mining Applications
With a concrete capacity of 5 m³, the Putzmeister Mixkret 5 complements the Putzmeister low-profile concrete mixer series. The machine is equipped with a powerful 168 kW diesel engine and Integrated Continuously Variable Drive (ICVD) to fully use the motor power at all times, without interruptions of the tractive force.

The new Putzmeister MT05 concrete batching plant is very compact. Specially designed for easy and effective transport and installation inside tunnels and mines.
Its mixing and production capacity makes it the ideal complement to any of our shotcrete conveyors. As the material is produced on site, it simplifies the process of production and stockpiling of shotcrete, reducing transport times and making the process more efficient.
