MasterRoc ACP 220

Anti-Clay Polymer for Treating Demanding Clays During Soil Conditioning in Tunnel Boring Machines (TBM)

​How does MasterRoc ACP 220 work?

MasterRoc ACP 220 is a next-generation, liquid anti-clay polymer formulated specifically for clay-rich soils with high clogging and adhesion tendencies. It reduces clay stickiness and adhesiveness, enabling easier and more reliable soil transport while minimizing TBM blockage risk.

MasterRoc ACP 220 can be injected directly into the cutterhead, excavation chamber, or screw conveyor to improve excavation efficiency in sticky clay formations, to reduce the risk of TBM blockage, and to facilitate easy and convenient muck transportations.

What are the unique features of MasterRoc ACP 220?

• Breaks down clay, reduces its stickiness and adhesiveness

• Prevents large lump formation

• Reduces cutterhead clogging risk

• Lowers torque requirements

• Improves soil consistency

What are the benefits of MasterRoc ACP 220?​

• Reduces blockages in cutterhead, working chamber, and muck transfer system

• Increases TBM advancing speed and production rate
