Geotechnical Engineering


Flexi Engineers provides a comprehensive geotechnical advice service. We have been conducting ground investigations for all infrastructure and construction projects with good feedback. Our multi-disciplinary team is uniquely placed to provide thorough geotechnical engineering services for all stages of your project from conception to completion.

We have provided geotechnical engineering services on a broad range of projects, including infrastructure, multi-storey buildings, housing developments, community facilities, heritage building adaptations, healthcare and medical facilities, shopping centres, aged care facilities and private residential projects.

We have developed a valuable resource by recording the results of our geotechnical investigations in our in-house database, Flexi Engineers Soils Map. This information is used not just by our engineers but is also available for external institutions and other interested parties — just one example of how our dedication to innovation sets us apart.

Whether you’re acquiring, selling, or developing land Flexi geotechnical engineers have the skills, knowledge and tools to manage even the most technically challenging projects.
