New techniques are generated by an increasing awareness of the need for below ground environmental protection. Their implementation requires continuous development and evolution of the techniques that can be applied.

The remediation of a polluted site, its treatment, the gradual elimination of a landfill or bringing it into conformity with legislation, the construction of a new engineered landfill, etc...

So many complex problems and so many special cases. To solve them requires to consider:

• ever more precise legislation,
• a concept of risk to the natural environment which is difficult to quantify,
• technical data linked to the physic-chemical nature of the pollution, the hydraulic, geological and geotechnical properties of the site.

  Soletanche Bachy, with its extensive geotechnical knowledge, its worldwide experience and its specially developed processes, is able to deliver solutions - from the design stage and the execution of the works to long term monitoring.

  A sustained policy of Research & Development is able to call on resources applied to the three main areas of techniques, materials and equipment.

  From its design office, equipment department and laboratory and also from a network of engineers located around the world, Soletanche Bachy can supply a turnkey solution to every specific ground related problem.

  Real-time instrumentation and measurement systems, which have been developed by Soletanche Bachy and its subsidiaries, enable control and monitoring of the various phases as the works are carried out.

  Long term monitoring which guarantees the longevity of the solution is provided by in situ measurements, the frequency of which depends on the sensitivity of the site and the manner in which it could develop. Incorporated from the design phase of a project, these measurements can be obtained using automated processes which reduce the operating costs.
