Geotechnical Engineering & Environmental Consultants
Based centrally on the Sunshine Coast
Tectonic is a group of specialist geotechnical engineers, engineering geologists and environmental scientists.
From the epicentre of our operations on the Sunshine Coast, we continue to make waves across South-East Queensland and beyond.
How can we help you?
Our Services
Slope Stability Assessment
At Tectonic we have grown to carry out over 300 slope stability assessments annually, and our team have experience individually of over 40 years specific to the coastal and terrestrial environments typical of south-east Queensland. Projects have included prominent state and local infrastructure, broadscale assessment of large development sites and specialist work on individual residential sites. We help clients navigate problem sites, and those developing or building in Council’s steep land or landslide hazard overlay areas.
Geotechnical Investigations
Geotechnical investigations obtain information on the physical properties of the underlying soil and rock prior to design and construction. With our wealth of local knowledge, we are able to offer up front discussion and tailor our investigations to suit the anticipated range of ground conditions and geo-hazards.
Acid Sulfate Soil Assessments
Our experienced scientists and engineers can provide site assessment and management advice to mitigate potential impacts relating to ASS to meet and comply with local planning schemes and policies.
Wastewater Treatment & Effluent Disposal
On-site wastewater and sewage treatment facilities are used for the treatment and disposal of wastewater and domestic sewage on properties in unsewered areas. We have a range of experience in demonstrating feasibility of on-site treatment for small residential projects, eco-tourism facilities and larger commercial developments. Previous work has included detailed modelling and successful negotiation with key stakeholders including Queensland Department of Environment and Science and SEQ Water.
Construction Stage Geotechnical Services
Tectonic’s experienced geotechnical engineers are available to provide a variety of services during the construction of your project, including design (e.g. temporary works) inspections, verification and certification.
Forensic Engineering & Expert Witness
Tectonic have a number of senior engineers with 30 to 40 years experience individually, and a proven track record in providing specialist geotechnical investigation and expertise in support of legal counsel.

Frequently Asked Questions
In Australia, the term geotechnical relates to the practical applications of geology, particularly in the realms of civil engineering and mining. Geotechnical companies in the country leverage this scientific knowledge to design earthworks and structure foundations, monitor site conditions, and facilitate foundation construction. Typically, these projects entail subsurface site investigations, examining bedrock, soil, and fault distribution.
In Australia, engaging a Geotechnical Engineer is crucial in various circumstances, particularly when undertaking construction or development projects. Here are common situations when you would need to enlist the expertise of a Geotechnical Engineer:
Land Development: Before embarking on any land development project, such as building residential or commercial structures, it’s essential to involve a Geotechnical Engineer. They assess the site’s conditions, including soil stability and composition, to ensure the feasibility and safety of construction.
Foundation Design: When planning to construct any structure with foundations, such as buildings, bridges, or infrastructure projects, a Geotechnical Engineer is instrumental. They provide insights into the appropriate foundation design based on the specific geological and geotechnical characteristics of the site.
Infrastructure Projects: Major infrastructure projects like dams, tunnels, highways, and airports require the expertise of a Geotechnical Engineer. Their role involves analysing subsurface conditions, evaluating potential risks, and providing recommendations to optimise construction and ensure long-term stability.
Site Remediation: In cases where land has been contaminated or compromised, a Geotechnical Engineer can assess the extent of the issue and recommend remediation measures. This is essential to ensure environmental sustainability and compliance with regulatory standards.
Natural Disaster Assessment: After natural disasters such as earthquakes, floods, or landslides, engaging a Geotechnical Engineer becomes crucial. They assess the impact on the land and structures, offering insights into the safety and stability of existing structures and providing recommendations for reconstruction.
Property Due Diligence: Before purchasing or developing a property, conducting a Geotechnical investigation is advisable. This helps identify potential risks and challenges associated with the site, allowing for informed decision-making and risk mitigation.
Renovation or Expansion: When planning significant renovations or expansions to existing structures, a Geotechnical Engineer can assess the impact on the site’s stability. This ensures that the modifications align with geotechnical considerations and do not compromise the integrity of the structure or surrounding environment.
In summary, engaging a Geotechnical Engineer in Australia is essential in a range of scenarios, from the initial stages of land acquisition to the completion of construction projects. Their expertise is integral to ensuring the safety, sustainability, and success of various development initiatives.
