Sika® Stabilizer-1518 TBM CA

FOAMING AGENT FOR TBM-EPBM TUNNELING

Sika® Stabilizer-1518 TBM CA is a specially designed liquid soil conditioning foaming agent without glycol. It has been formulated to be used with earth pressure balance machines (EPBM) for modifying the properties of the excavated soil particularly in highly cohesive soils.

  • Modifies properties of the excavated soil
  • Improves the excavation process and TBM performance
  • Can be used in acid and basic soils
  • Lubricating properties minimises friction between soil particles and reduces the cutting wheel torque
  • Prevents clay from plugging
  • Reduces dust in the air and decreases the wear of cutters in rock excavation
  •  Easy to handle and use
  • Normal or hard fresh water can be used to produce the foam
