FIND OUT OUR SOLUTIONS FOR UNDERGROUND WORKS >> 

Briefly...

  • 26 years experience
  • 190 kms of tunnelling, and more than 16 millions m3 treated

 We have acquired an expertise and experience in the treatment of bentonite slurry which is recognized throughout the world (click and see our references list), largely through the world’s largest realisations :

  • Tuen Mun Chek Lap Kok (Hong Kong) : 1 x 17,6m
  • Shanghai : 2 x 15,43m
  • Groene Hart (The Netherlands) : 14,87m
  • Moscow : 14,2m

Innovation

We intervene in complex confinement projects, where constraints such as unstable soils, permeability and hydrostatic pressure are often considerable. The stake is to be able to all geological conditions through development of individually tailored, modular and flexible competence.

Patented system of slurry management for rapid modification of the density and viscosity.

Processing of excess water and mud (by pressing and centrifuging) to enable its discharge, reduce costs and allow the valorisation of excavated materials.

Commitment to performances

MS commits itself on contract to a daily and weekly progress, with a previously established maximum efficiency.

Water : a priority

For 26 years from now, MS has been transforming used water and mud, as well as worksite wastes, into compact cakes, which can be easily loaded, transported, thus regenerating large quantities of clarified water, that can either be reused in the process, or safely discharged into the natural environment.

Solutions for the whole kind of tunnels

In annex to the sites bored with pressurised-slurry tunnelling machines, but also for those using earth pressure balance machines (EPB) or traditional methods, MS designs, manufactures and installs adapted solutions : Site and seepage water treatment plant (please also see our page about "environment"), bentonite preparer/batcher, on-board desander, wide range of desanders.

 

At your service everywhere, at every stage, and at every moment

In addition to project management our experienced staff is there to help you at the pre-project phase – geological/geotechnical analysis, choice of bentonite… - or to assist you everywhere on site anywhere in the world on short- or long-term assignments – exploitation assistance, training, general supervision…
