Dam, Stop Banks, TSF Designs


Water storage for irrigation and human use, levees and protection structures for flood flows, climate change and increasing populations are driving the need for better use of this precious asset and protection from wilder weather and sea level rise.
By nature, these large storage and protection works carry high to very high levels of risk and require very deliberate and careful consideration. In the 21st century the industry is held to an higher level of social accountability. Flood protection stop banks almost experience 1-in-100 year events annually. Climate change is playing a pivotal role in governments’ asset management programmes.


RDCL undertakes geotechnical and geophysical engineering across many aspects of dams and stop banks including;

  • Preliminary site investigations
  • Detailed site investigations of existing assets
  • Geophysical surveys
  • Potential failure modes analysis (PFMA)
  • Preliminary and detailed Dam Design
  • Site Engineer
  • Risk Management
  • TSF geotechnical design
  • TSF closure assessment
  • TSF liquefaction assessments
  • Peer Review

RDCL’s teams deploy across New Zealand and Asia to undertake on-site testing and assessments across many different dams, stop banks and tailing storage facilities. RDCL delivers high quality datasets and QA on site works including drill supervision and core logging, CPT operations and geophysics surveys. Combining these datasets ensures clients better understand risk and remediation.
