Do you need a Slope Stability Assessment?
Building a new residence, extending your existing dwelling or planning any type of development on sloping ground?
Slope stability assessments give an appraisal of the hazard presented from landslide at your site, find potential higher risk areas, and recommend ways to keep your site stable. Such an assessment is mandatory as part of the development application or building approval process if your site is located within Council’s Landslide Hazard or Steep Land overlay areas. You can search Council websites to check at the links given below or contact us to obtain more information.
A standard slope stability assessment would usually comprise:
Desk study of existing maps, aerial photos, and the soil test report.
Site walk-over mapping by an experienced geotechnical professional.
Preparation of a letter report with the slope stability risk assessment and geotechnical advice for the project.
For more complex sites, subsurface investigation, often by test pitting and drilling boreholes, is carried out, followed by targeted laboratory testing. Where necessary, we also conduct numerical modelling using computer software to provide quantitative assessment of slope stability.
If a landslide has occurred the costs and difficulties in repairing damage to land, infrastructure and property can be extreme. We have extensive knowledge in landslide investigation and remediation, with our team having successfully completed dozens of such projects across the Sunshine Coast.
