Many parts of the Far North have been subject to a turbulent geological history and consequently can be subject to weakness, slow deep creep and/or sudden slippage - particularly where those soils are exposed to water logging and erosion. Collectively, our Engineers have many years experience with the variable local geology and in identifying where these risks can occur. We provide geotechnical advice and cost-effective solutions for difficulties on your site.
Following major storm events in March & July 2007 and January 2011, Haigh Workman was involved in many slip assessments and repairs near houses and road sides, working within Earthquake Commission guidelines. We routinely use slope stability assessment software to assess natural stability, the effect of proposed modifications to land and to develop stabilisation solutions. We regularly review new technologies to keep up-to-date with the growing range of solutions available. We are pleased to have been able to put our geotechnical skills to good use for the Earthquake Commission in Christchurch since February 2011, carrying out geotechnical investigations and land damage assessment.
Geotechnical Engineering services we offer include:
- Pre-purchase and predevelopment assessments
- Foundation design
- Retaining wall design
- Slope stability modelling and stabilisation design
- Slip repairs
- Construction Monitoring
