About this project

To investigate the potential of soil stabilisation techniques to increase the range of soils which could be suitable for construction of slurry storage lagoons.

To find a suitable treatment to make soil ‘impermeable’ and retain stability under wetting and drying conditions, which would enable more farmers to adopt this form of storage. 

Two different sub-soil types (sand and chalk) were mixed with different:

  • Amounts of added cement powder
  • Moisture contents
  • Degrees of compaction 


  • To be deemed impermeable, a soil must have a permeability of 1x10-9ms-1 or less; none of the soils tested managed to meet the required criteria
  • There was no correlation between the treatments and soil type with degree of impermeabilty attained
  • A consequent review of the work has suggested that lime may have been a better add-mixture
  • Further enquiries have confirmed that the technique is being used successfully for the construction of landfill sites and sealing contaminated soils, indicating that the technique does have potential
