Soil stabilisation

Addition of binders to soil to reduce material importing and off-site disposal. Post-stabilisation testing is also carried out.

  • Field control testing –
    On-site control tests include:

    • Pulverisation
    • MCV
    • CBR (in-situ)
    • Plate Bearing
    • Density/Moisture (in-situ)
  • Lab trials – Assessment of host soil properties and improvements to stabilised materials following addition
    of binders.
  • Value engineering – Advice on best practice, mix design and tailored recommendations.
