Soil Mix Remediation Project (SMiRT)
Development
Field trials
Laboratory treatability study

• Development, construction and validation of novel
  soil mixing equipment capable of delivering both
  wet and dry binder
• Quality assurance software system which will
  monitor variables such as binder pressure,
  injection quality and rate, impact depth,
  penetration and withdrawal rates will be designed
  and implemented

• A range of conventional and novel binders as well
  as additives will be used
• Extensive laboratory study will be performed to
  optimise the selection of the materials
• A number of tests will be performed strength,
  density, leachability, sorption and desorption
  and compressibility

• Trials on a selected site with variable ground
  condition and contamination
• Permeable reactive barrier will be performed
• Hot spot treatment of contaminated ground as well
  as improvement of soft soil will be carried out
• Both wet and dry binder delivery will be performed

Kentish Minerals
Field samples testing
Field monitoring and testing
Stakeholders meeting

• Brainstorming and info-exchange workshops will be
  held and stakeholders issues will be addressed

• Site trial samples will be tested for a range of
  properties
• Variation between wet and dry binder, depth,
  different installation techniques, treatability
  study and field performance will be investigated
• Long term performance will be assessed

• Boreholes for groundwater monitoring
• Coring of the hot-spot treatment and ground
  improvement sections
• Treated blocks extruded for inspection purposes

BURA
Dissemination of results

• Research and development findings will be
  disseminated with CLAIRE and IPM-Net
