MS approach

We believe that, for future generations, construction must become more sustainable.

Our Business

Underground Works

Crossing mountains, linking continents, enabling people to move around... Underground construction is probably the most appropriate response to the rapid urbanization of tomorrow's cities.

Mineral Industries

Because sand is the second most important resource consumed by mankind, and because natural sand resources are becoming increasingly scarce, let's work together to create tomorrow's solutions for valorizing and saving this resource.

Water Treatment

« L’eau n’est pas source de vie, elle est la vie » (Antoine de Saint Exupéry). Because water is our most precious resource, its preservation is the duty of us all.

Water treatment


Circular economy means economy. Because we're convinced that we can help preserve nature while offering you sources of competitiveness.
