Soft soil treatment

Innovative soft soil treatment

The Ballina region is characterised by complex geotechnical conditions, including deep soft soils in the flood plain areas.

Soft soils have been an important consideration throughout the design phase of the Pimlico to Teven project and the proposed treatments will continue to be an important activity during the construction phase.

A combination of treatments will be used to address the soft soil issues, as listed below:

  • Low embankment strategy
  • Deep soil mixing
  • Wick drains
  • Concrete injected columns
  • Driven concrete columns
  • Surcharging

The following short video from the Ballina Bypass project explains the soft soil treatment process.
