Soil Mix Remediation Project (SMiRT)

Development

Laboratory treatability study

Field trials

  • 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 monitoring and testing

Field samples testing

Stakeholders meeting

  • 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
  • Brainstorming and info-exchange workshops will be held and stakeholders issues will be addressed
  • 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 CLAI:RE and IPM-Net
