Hard Rock Tunneling

Advanced chemical technologies for rock stabilization, water control, and TBM support—engineered for high-strength rock conditions, fractured zones, and demanding underground excavation environments.

Cormix delivers comprehensive chemical solutions for hard rock tunneling, designed to improve ground stability, control water ingress, and enhance TBM and drill & blast performance in challenging geological conditions. These systems are engineered for high-strength rock, fractured formations, and zones affected by high groundwater pressure.

Our technologies include polyurethane and epoxy injection systems for rock consolidation, fast-reacting foams and hydro gels for water sealing, soil and rock conditioners to optimize TBM excavation, and high-performance lubricating greases for cutter head and shield protection.

By minimizing water inflow, stabilizing fissures, and improving machine efficiency, Cormix solutions reduce downtime, extend equipment lifespan, and enhance overall safety during tunnel excavation and lining works. These products provide reliable, long-term support for critical underground infrastructure projects.
