Cormix SCF series


Soil Conditioning Foam for TBMs

Cormix SCF series  is a liquid foaming agent produced especially for soil conditioning with shielded tunnel boring machines. 

Cormix SCF series  is used in soft ground tunneling with tunnel boring machines, it can be modified to match the properties of the soil to be excavated, trials are recommended at Cormix  Laboratories to determine the most effective foam type.

Advantages include : –

  • Improved soil behavior.
  • Easier mucking.
  • Reduced permeability & improved sealing at the face.
  • Can reduce stickiness of soils reducing blockages.
  • The soils properties are made more plastic giving more even and controlled support & better stability at the face.
  • Reduces friction & abrasion to the cutter head, screw conveyor & conveyor reducing wear costs and power consumption
