Geo Engineering & Geotechnical Services

Innovative Solutions for Growth

Explore our comprehensive selection of services that cater to a variety of needs, ensuring complete customer satisfaction.

01.

LiDAR

We offer LiDAR drone and airborne LiDAR services for precise terrain mapping and modeling, even in forested or challenging areas. Our LiDAR drones suit small to mid-sized sites, delivering fast, sub-meter accuracy for slope analysis, geohazard mapping, and earthwork planning.

For larger or remote sites, airborne LiDAR via aircraft provides wide-area coverage for geological mapping, flood assessment, and slope hazard zoning. All LiDAR data integrates with photogrammetry, MASW, resistivity, and soil investigations for a complete ground analysis.

Geoforensics Assessment

Geo-forensic assessment offers a new perspective of assessing post failure events as it requires a wide range of information, identifying features on surface and subsurface, with analysis requiring input from multidisciplinary subjects together with geoscientific study. There is no such ‘one size fits all’ solution. This is due to the different behavior and characteristics of the geologic material. One method may be subject to data availability & coverage, scale of the area, subjectivity towards a qualitative/heuristic interpretation. Therefore, a multiple approach is needed to tackle complex issues on site.

Geological Map Assessment

Geological mapping is the process of creating a detailed and accurate representation of the geology of a particular area. This involves gathering data about surface and subsurface features and creating maps and diagrams that illustrate their distribution and characteristics. The process of geological mapping typically involves a combination of fieldwork and laboratory analysis.

Slope Hazard

Slope hazard and risk assessment is essential in civil engineering to evaluate potential slope failures caused by natural factors like rain or earthquakes, or human activities such as excavation and construction. It helps identify risks early and prevent disasters like landslides and erosion. The process involves collecting geological, hydrological, and topographical data through site investigation (SI), followed by slope stability analysis to determine the factor of safety (FOS). Based on this, engineers propose mitigation measures such as retaining walls, soil reinforcement, drainage systems, and maintenance plans to ensure long-term slope stability.

Electrical Resistivity

Electrical Resistivity Survey is a non-invasive geophysical method used to map subsurface conditions by measuring how soil and rock resist electrical current. It’s commonly used to detect groundwater, faults, sinkholes, and soil layers — making it ideal for site investigation, slope studies, and environmental assessments.

Aerial Photogrammetry Surveying

Aerial Photogrammetry Surveying is a cutting-edge mapping solution that uses drone-captured images to generate accurate 2D maps and 3D models of the earth’s surface. This method is ideal for large-scale land surveys, construction planning, volume calculations, and visual inspections offering fast, cost-effective, and high-resolution data with minimal site disruption.

MASW (Multichannel Analysis of Surface Waves)

MASW is a non-invasive geophysical method used to determine subsurface stiffness and stratigraphy by analyzing surface wave velocities. It’s ideal for identifying soil layers, bedrock depth, and weak zones, making it essential for geotechnical site investigations, seismic hazard assessments, and foundation design.

Soil Investigation

Soil Investigation is a vital process in geotechnical engineering that assesses subsurface conditions to ensure safe, stable, and cost-effective construction. It includes field drilling, in-situ testing, and lab analysis to determine soil strength, classification, and groundwater levels — forming the basis for foundation design, slope engineering, and risk assessments. The data collected is also essential for slope stability analysis, where factors like geology, hydrology, and topography are analyzed to calculate safety factors (FOS) and recommend appropriate mitigation measures such as retaining walls, drainage systems, or soil reinforcement. Combined with monitoring and instrumentation, this service helps detect potential ground movement and supports long-term slope and structure performance.

Geophysical Surveying

A geophysical survey is the key to provide the best solution for all the matter above. It comprises a non-destructive ground survey such as electrical resistivity, seismic refraction /reflection/Multi-channel Analysis of Surface Wave, ground penetrating radar (GPR), gravity and magnetic survey. Each geophysical methods uses either electrical injection, waves penetration or recording passive gravitational and magnetic forces. Data recorded were translated into 2D and 3D anomalies with specified depth, giving an insight of potential mineral deposits, groundwater aquifer, settlement-cavity hazard zone, geothermal activity and fracture zones. In comparison to other conventional mapping methods, geophysical survey effectively reducing cost for site investigation and planning works of a large area.

Digital Shoreline Analysis System (DSAS)

DSAS is a geospatial tool used to calculate shoreline change over time using historical and current data. By analyzing satellite imagery, aerial photos, and GPS data, DSAS helps identify erosion or accretion trends, monitor coastal dynamics, and support sustainable shoreline management. It is a valuable solution for planners, developers, and environmental consultants working in coastal or riverine zones.
