Sika® Foam TBM-101 FB (TH)


Sika® Foam TBM-101 FB (TH) is a liquid foaming agent based on biodegradable anionic surfactants and a high efficiency polymer.

  • Produces stable foam which can easily injected in High to low permeability soils reducing the risk of front shield pressure loss.
  • It can be used both in acid and basic soils.
  • The high efficiency polymer allows keeping the shield clean from clays.
  • Its lubricating capacity minimizes friction between soil particles and reduces the head torque.
  • Easy to handle.
  • Fresh and hard water can be used.
  • Eliminates dust in air drilling and reduces the wear of cutters also in rock excavation (adopt a FER 10 – 20 and a FIR 15 – 30).
  • Prevents clay from plugging.
