A multi-application technique<\/strong><\/p>\n<\/div>

Soletanche Bachy offers you its full range of Deep Soil Mixing processes for ground improvement, cut-off walls applications or support of excavation.<\/p>\n<\/div>

What is Deep Soil Mixing ?<\/h2><\/div>

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\u00ae<\/a> 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.<\/p>\n

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.<\/p>\n<\/div>

This technique encompasses several different processes:<\/h3>\n<\/div>
\"\"<\/div>

Colmix\u00ae<\/h3><\/a><\/div>
<\/div>
\n

Colmix\u00ae process,<\/strong><\/p>\n

which enables the formation of columns using one or more vertical rotating tools with mixing blades and mounted on piling rigs.<\/p>\n<\/div>

Geomix\u00ae<\/h3><\/a><\/div>
<\/div>

Geomix\u00ae process,<\/strong><\/p>\n

which creates wall panels using a CSM (Cutter Soil Mixing) tool based on technology derived from the Hydrofraise\u00ae process.<\/p>\n

Springsol\u00ae<\/h3><\/a><\/div>
<\/div>
\n

Springsol\u00ae process,<\/strong><\/p>\n

uses a small-diameter auger to form small-diameter vertical, inclined or sub-horizontal columns. This process is particularly suitable for use in confined spaces or where working height is limited.<\/p>\n<\/div>

Deep Soil mixing applications<\/h3>\n

Deep Soil Mixing has many applications<\/strong> across a broad spectrum of construction projects, including:<\/p>\n

    \n
  • The improvement of compressible soils<\/strong> subject to distributed loads: industrial warehouses, storage areas and linear structures such as rail and motorway embankments<\/li>\n
  • The treatment of soils<\/strong> to mitigate the risk of liquefaction<\/li>\n
  • The construction of continuous cut-off walls<\/strong> on levees and dikes, or low-permeability enclosures to contain polluted areas<\/li>\n
  • The construction of temporary or permanent retaining structures<\/strong> in combination with vertical strengthening elements (steel beams, pipes and\/or pre-cast piles)<\/li>\n
  • Consolidation of embankment\/cut slopes<\/strong> using transverse shear walls<\/li>\n<\/ul>\n

    Generally speaking, this technique is appropriate for any soil type. The soil\/binder mix is a semi-rigid material behaving halfway between natural soil and concrete, and offers improved mechanical and hydraulic properties compared to the original soil.<\/p>\n<\/div>
