KBRseries are eco-compatible polymer reinforced liquid foaming agent produced especially for soil conditioning in shielded tunnel boring machines in silt to sand soils which may contain a high amount of water and designed to improve safe and efficient soil extraction.

Applications and benefits:

  • Improved soil behavior
  • Highly reduces friction & abrasion to the cutter head, screw conveyor & conveyor
  • The soils properties are made more plastic giving more even and controlled support & better stability at the face
  • Reduced permeability & improved sealing at the face
  • Binds excess water
  • Easier mucking
  • Facilitates soil conveyance
  • Anti-corrosive effect on drilling equipment
  • Reduces overall resistance when drifting
  • High resistance to changes in pH and water hardness
  • Highly biodegradable
