Identifying Underground Cavities
Underground cavities, whether formed by natural processes (such as karst formations) or human activities (like mining), can pose significant risks. These risks include ground subsidence, structural collapses, and potential harm to infrastructure and human safety.
Our Solution:
-
We employ advanced geophysical techniques, including Electrical Resistivity Tomography (ERT) and Ground Penetrating Radar (GPR), to detect underground cavities at an early stage. These non-invasive methods provide complementary insights into subsurface conditions, ensuring accurate and reliable detection of voids or cavities.
-
• Electrical Resistivity Tomography (ERT)
Measures the electrical resistivity of the subsurface to identify anomalies that may indicate the presence of cavities. Ideal for deeper investigations and large-scale mapping. Helps prevent accidents, mitigate structural damage, and ensure safety by enabling early intervention.
-
• Ground Penetrating Radar (GPR)
Uses high-frequency electromagnetic waves to detect changes in subsurface materials, including voids and cavities.
-
Provides high-resolution, real-time imaging, making it highly effective for shallow-depth investigations and detailed mapping. Complements ERT by offering precise localization of cavities and their dimensions.
-
Our integrated use of Electrical Resistivity Tomography (ERT) and Ground Penetrating Radar (GPR) delivers comprehensive detection, offering a complete understanding of subsurface conditions from shallow to deeper depths. Early detection enables timely intervention, minimizing risks such as ground subsidence, collapses, and structural damage. This approach ensures reliable and efficient risk management without compromising sensitive information.
Evaluating Landslide Risks
Landslides pose significant threats to lives, infrastructure, and the environment. Accurately understanding their size, boundaries, and the depth of slip surfaces is critical for effective risk mitigation and planning.
Our Solution:
-
We utilize Electrical Resistivity Tomography (ERT) to assess landslide risks with precision. This advanced geophysical method enables us to:
-
• Map Landslide Boundaries:
Identify the spatial extent of unstable areas and high-risk zones.
-
• Determine Slip Surface Depth:
Locate the depth of potential failure planes to understand landslide mechanics.
-
• Estimate Volumes
Calculate the volume of material at risk, supporting targeted mitigation strategies.
-
ERT measures subsurface resistivity variations, highlighting contrasts between stable and unstable materials (e.g., saturated zones, weak layers). By delivering high-resolution data, ERT empowers proactive risk management, infrastructure protection, and community safety. This non-invasive approach ensures informed decision-making and long-term stability in landslide-prone regions.
Optimizing Quarry Expansion Through Subsurface Insights
-
As quarry operators expand extraction zones, accurately mapping subsurface composition is critical to avoid costly missteps. Challenges include:
-
• Identifying High-Quality Resources:
Distinguishing gravel, sand, bauxite, or massive rock formations from unproductive materials.
-
• Minimizing Waste:
Avoiding investment in areas with low-value or unusable materials.
-
• Maximizing Efficiency:
Preventing missed opportunities by locating resource-rich zones with precision.
Our Solution:
-
We utilize Electrical Resistivity Tomography (ERT) combined with chargeability measurements to deliver high-resolution subsurface imaging. This integrated approach enables:
-
• Resource Targeting:
Pinpoint zones rich in gravel, sand, bauxite, or massive rock by detecting resistivity contrasts between materials.
-
• Material Differentiation:
Chargeability data helps distinguish between exploitable resources (e.g., dense rock) and low-value or saturated layers.
-
• Validated Accuracy:
Our findings are cross-checked with verification drilling, ensuring reliable data for confident decision-making.
-
By mapping subsurface composition non-invasively, we empower operators to optimize extraction plans, reduce exploration costs, and maximize resource recovery. This proactive strategy minimizes risks while unlocking the full potential of quarry expansions.
