A multi-application technique
Soletanche Bachy offers you its full range of Deep Soil Mixing processes for ground improvement, cut-off walls applications or support of excavation.
The technique was created in the 1970s and 1980s in Japan and Scandinavia, initially to improve the bearing capacity of very soft clay soils. Bachy was a trailblazer in this field, introducing its Colmix® process into Western Europe as early as 1986. Since then, the Deep Soil Mixing technique has been extended to a wide range of soil types and applications.
In practice, this technique consists of mechanically mixing the in-situ soil while incorporating a cementitious material, which is usually made of one or several hydraulic binders such as cement, blast furnace slag, lime, fly ash, etc.
