SNF provides solutions for underground projects, from front shield to mud conditioning, transportation, and waste management. Our products ensure that tunneling operations run at peak efficiency while minimizing waste. SNF civil engineering experts are always available to support operations through to completion.
Subcontractors specializing in tunneling, pipejacking, and HDD use specific drilling fluids to carry out their projects. The success of excavation at optimal costs depends on the properties of drilling fluids to achieve targets such as:
- Carrying cuttings from bottomhole
- Ensuring the stability of the cutting front
- Preventing water infiltration
- Avoiding fluid losses
- Minimizing filtrate
- Facilitating drilling mud treatment
In TBM projects with mud (Mix Shield or Variable Density) or foam (Earth Pressure Balanced Shield), there is a growing demand for innovative additives to improve productivity while reducing the impact on the environment. SNF is at the forefront of innovation by offering ever more sophisticated products that meet the most advanced requirements.
