Our qualified geotechnical engineering team have been involved in a diverse range of projects, equipped with the experience to mitigate risk and propose a cost effective design in accordance with your project’s objectives. Some of the services we offer are:


Geotechnical site investigation and reports


Pre-purchase geotechnical assessments


Site suitability and feasibility assessments


Forensic geotechnical investigation


Detailed Seismic Assessments – Geotechnical assessment of foundation systems


Design of building foundations


Earthquake assessments – liquefaction analysis, slope stability assessment, retaining wall assessment, assessment of horizontal and vertical displacements due to seismic demands


Ground improvement – bulk earthworks, lime and cement stabilisation, stone columns and jet grouting


Slope stability analysis and slope remediation design


Earthworks – land development, cut fill planning and quantity assessment, specifications, construction monitoring

Earthquake Experts

Our team has completed over 1000 detailed geotechnical reports for insurance companies, the Earthquake Commission and private clients providing details regarding land performance.  Investment in ground improvement and robust foundations may not be visible in the finished development, but we understand that the assurance that a building has been constructed on a stable foundation provides reduced insurance risk, increased resilience for future earthquake events and peace of mind for owners and occupants.
