State-of-the-art tunnelling tools
and auxiliary products
A Tunnel Boring Machine (TBM) without effective digging tools (cutters) is like a toothless lion. Our state-of-the-art TBM cutters are cutting rings and we call them RingX ®.
RingX ® are the spearhead of a wide range of high-end tunnelling equipment that we provides in the field of industrial excavation and drilling:
– BrushX: “tail brushes” with high performance, which, mounted on the TBM, ensure a perfect distribution and sealing of the backfilling mixture used for tunnelling.
– Chemical consumables: a wide range of sealants, resins and soil conditioning agents that facilitate drilling.
– Grout and bentonite: supply of the best raw materials and design of the right backfilling mixtures necessary for tunnelling procedures.
