Anti-clogging Agents

Normet’s anti-clogging agents are specially formulated to reduce clay clogging and re-agglomeration in TBM operations. Available in both foaming and non-foaming variants, these agents are tailored to suit different clay formations and soil conditions. They improve cutterhead efficiency, reduce downtime, and ensure smoother excavation in sticky, cohesive soils—enhancing the performance and sustainability of Earth Pressure Balance (EPB) and slurry TBMs.
