Service Segment:
The services rendered by IGG Services (P) Limited have applications in various areas. Following is a brief list of application areas:
Civil Engineering
Dam Safety
Dredging & Desilting Monitoring
Mining exploration
Reservoir Sedimentation
Marine
Ground Water
Environmental Impact Assessments
Road Condition Evaluation
Topographic Surveys
Vibration Monitoring
Engineering Geology
GIS ServicesCivil Engineering:
All large projects of civil engineering like dams, tunnels, high rise buildings, transmission towers, power houses, underground structures, airports etc., require precise information of subsurface, like overburden thickness, profile of bedrock, quality and strength of foundation etc. Traditionally boreholes drilled at regular intervals provided this information. However, in complex geology, this discrete information at times is insufficient. Geophysical methods provide quick, economical and continuous information on the area of study, and considerably reduce the drilling budget and remove ambiguity to a large extent.
- Foundation Studies- dams, towers, bridges, high rise buildings,
- Bedrock Properties & Overburden Mapping
- Tunnel Route Investigations
Dam Safety:
Dams are pride of civil engineers. Built for various benefits like power generation, irrigation, these are structures costing a huge amount of money, and are meant to serve for long periods. For various reasons, there is degradation of dam structures with time, and a precise insight into them, can help design rehabilitation package. By virtue of being non-invasive and non-destructive, geophysics plays an important role in studying dams, to detect degradation, loose pockets, sink holes, and other problems.
- Non Invasive inspection of dams
- Leakage path detection
- Sink Hole Mapping
- Concrete degradation determination
- Pre-grouting & post-grouting monitoring
Dredging & Desilting Monitoring:
Dredging is regularly carried out at ports, lakes and rivers to remove accumulated silt and sediments. The services rendered by IGGS help identifying various layers of sediments, determination of level of compaction and dredging monitoring.
- Dredging quantity determination
- Dredging quality monitoring
- Pre-dredging evaluation of sediment’s properties
Mining exploration:
- Ore body mapping
- Rippability/ excavability studies
- Slope stability studies
- Vibration Monitoring
- Ground water studies
