Looking for a powerful and easy way to get rid of your used sludge, even the most liquid or the most impervious?

Want to manage dry spoils and

reuse the filtered water?

Whether this sludge comes from boring a tunnel with a slurry shield or variable density TBM, or from foundations works, we are constantly improving our treatment processes and the ease of installation of this technology on construction sites:

  • Possibility of very high efficiency plants able to treat up to 10,000 m3 / day
  • Unique ability to adapt to variable density sludge, potentially with a high bentonite content, with over 200 references
  • Sale with buy-back option or rental offer


We transform the waste sludge into compact spoils. The operator can easily evacuate them. We thus generate large quantities of clarified water that can be reused or released into the natural environment without any risk.

More than 240 of bored tunnels
30 years of experience
More than 1 millionm3 of water treated
Over 20 millionsm3 process


From short-lived constructions... up to new durable plants !
