Thanks to the experience gained in underground construction sites, RM® has developed a wide range of spare parts for shotcrete machines. The importance of shotcrete machines in the complex context of mining and tunneling, requires a careful selection of the materials used and the processing phases of every single wear component in contact with the concrete as it is highly subject to wear. The feedback with the end user and RM®’s experience gained through years of activity in this industry, has allowed us to perfect specific solutions, offering high performance and improving reliability with maximum attention to operational safety.
- Protection from falling material, during the foundation excavation or tunnel construction
- Blocking any water leakage from the walls of an underground tunnel
- Consolidation works (embankments, slopes), as well as rehabilitation work (degraded buildings)
Unlike traditional concretes, which are placed inside formworks and subjected to vibration to remove excess air in order to increase product compaction; for shotcrete, placement and compaction take place in a single operation.
Spritz beton (German term) or shotcrete (English term), is mainly used in underground construction. Concrete compaction is achieved by exploiting the speed of the impact of the mix against the walls of the substrate.
