By injecting the conditioning products directly on the front and/or the excavation chamber it is possible to change the spoils' substance from solid to plastic, thus making it possible to:
- Spread the excavation pressure evenly on the excavation front
- Reduce friction and consequently the energy needed for excavation progress
- Improve earth movability with the auger.

The polymers (INNpol series) increase half-life, substance and lubricating power of foam.
InnoTek offers a wide range of conditioning agents and tailor-made products for conditioning all types of soil. Our staff's experience and professional skill are always available to help customers to optimise products depending on the features of the type of ground the TBM shall pass through.
