Deep soil mixing – an efficient mobile in-situ process - has widespread from construction to remediation and waste treatment and uses both lime and blended binders.​

The deep soil mixing process, originally developed to stabilise thixotropic clays in thick layers, has widespread to the remediation and waste treatment branches. This process has several benefits:
  • In-situ operation – the treated material is treated at its original location; no handling costs occur here
  • Mobility – the machinery is attachable to conventional excavators and uses mobile tanks for binders; it can move to distant or difficult access locations
  • Flexibility - speed of works is practically given by number of machines and can be adapted to the total project schedule
  • Precision – the binders dosage is adjusted automatically based on the operation speed, using specialised software
Deep soil mixing has proven its efficiency at many types of materials and projects, as:
  • Dredged sediments treated on site or at lagoons
  • Coal combustion products stabilised at deposits
  • Petrochemical sludge pre-solidified in situ for further treatment
  • Coal sludge treated in situ 
  • Contaminated soils of many types stabilised in situ or at deposits

Key applications

Key benefits of STABICALCO range and cooperation with Carmeuse at deep soil mixing application projects
  • Process and applications know how enabling the right choice of STABICALCO “Q” quicklime type in terms of reactivity and granulation 
  • Customising of STABICALCO QB binders to a given project
  • Long-term relationship and experience with deep soil mixing machinery producers and operators
