Engineering and Environmental Geophysics
Total Scan Survey prides its self on our geophysics department providing high quality professional services for all aspects of engineering, environmental and geo-technical investigations, with offices in Perth, Sydney, Brisbane, Melbourne and their surrounding areas. Our team are regularly called on for engineering, development and environmental projects across Australia.
With our fully trained team of Engineering Geophysicists, Consulting experts and consultants we perform a high standard Survey with full QA/QC and offer an output using a number of mapping applications.
Our operatives can accurately map buried anomaly information to create a very effective subsurface mapping solution.
Producing subsurface information for a variety of clients, our output is to an extremely high standard and OHS sound.
Setting out roads, pipelines, car parks, we are experienced in providing complex survey engineering services and solutions.
Additional surveying services can also be undertaken as listed below…
With our proven track record on many large-scale projects Australia wide, we can provide extensive analysis for environmental and engineering purposes of many environmental and geological aspects such as;
- Land fill sites
- bedrock mapping
- grave site investigations
- electromagnetic resistivity & conductivity studies
- Subsurface investigations for sheet piling
- Contaminate Plumes & Soils
- Karst anomolies
- Geo-Acoustic methods
- Seismic Refraction
- Multi-channel analysis of surface waves (MASW)
- Seismic Reflection (Small to medium size)
- Geo-Electric methods
- 2D/ 3D Electrical Resistivity Tomography (ERT)

- Conductivity Mapping Electromagnetics (EM)
- Marine Electrical Resistivity Tomography (ERT)
- Cross-hole ERT
- Borehole-to-Land ERT
Total Scan & Survey provides professional services for geophysical surveying and ground-penetrating radars. This is to make sure that very effective subsurface mapping solution is provided.
Ground-Penetrating Radar is a geophysical method that uses radar pulses to image the subsurface. This non-destructive method uses electromagnetic radiation in the microwave band (UHF/VHF frequencies) of the radio spectrum, and detects the reflected signals from subsurface structures. GPR can be used in a variety of media, including rock, soil, ice, fresh water, pavements and structures. It can detect objects, changes in material, and voids and cracks.
Earth Grounding Surveys Designing effective earthing systems should consider the type of soil and the key parameter is Soil Resistivity that influences discharge and passage of excessive fault current(s) into the earth as a safety or protective measure.
Industrial Grounding Surveys For Substations, industrial and infrastructural electro/mechanical projects, TSS offers grounding resistivity surveys in accordance to ‘BSEN50522:2010 Earthing of Power Installations standards using the latest equipment innovated to solve grounding challenges even in the most resistive soils.
Underground Leakage detection In context of concrete band reservoirs, chemical or waste holding, leakages of contaminants through concrete and further into the earth, may indirectly contaminate groundwater table or directly incur environmental penalties.
TSS has innovative methods of investigating and characterizing leaks using a blend of high-resolution ground penetrating radar GPR for near surface or in combination with Ultrasonic in concrete.
Electrical Resistivity Tomography (ERT) Surveys Depending on the objective, we offer a wide range of multi-dimensional (2D/3D) Electrical tomography imaging applications:
2D / 3D Electrical Resistivity Tomography (ERT) We offer standard and tailor-made options of high-resolution ERT imaging ranging from shallow geotechnical or environmental investigations to several hundred meters depth surveys for groundwater exploration and mineral exploration.
Our field data acquisition, processing procedure, interpretation and reporting conforms to ASTM D6431-99(2010) and BS: 5930:1999 working standards
P-wave Seismic Refraction Surveys Especially for site investigations and engineering design projects, we offer high resolution seismic refraction and MASW surveys. Our field data acquisition procedure, processing flow, interpretation and reporting conforms to ASTM D777-00(2011) e1 standard.
Seismic Refraction surveys Depending on the geology and survey objectives, we can design, test and acquire P-wave refraction and shear wave MASW using either traditional 24/48 channel set-ups, distributed systems or continuous profiling roll-along techniques to acquire several kilometer profiles data.
Multi-Channel Analysis of Surface Waves (MASW) Shear-wave velocity (Vs) and its other forms like Vs30 are directly related to earth stiffness and load bearing capacity, hence its importance for engineering design and geo-hazard assessment site investigations.
Depending on project objectives and client’s requirements, we can design and acquire high resolution MASW surveys for a range of applications.
At Total Scan & Survey, we offer the most efficient service in engineering and environmental geophysics in Perth, Sydney, Brisbane and Melbourne and the surrounding areas.
