Main works - Civil engineering

Along with its original activities in sand pits, Sotres has developed a large range of desanders for drilling mud, using the principle of liquid-solid separation through cycloning for the mud bentonite regeneration used in the field of special foundations.

The desanders, adapted to each type of work, are used for

-  Tunnels
- Anchors
- Piles
- Cast concrete walls (hydromill)
- Directional well drilling  
- Geothermic drilling
