Seismic Imaging

Seismic Imaging

Wave & Vibration Based

Simple Explanation

We use controlled vibrations to reveal subsurface layers, weak zones, and stiffness changes before construction starts.

Best for: Layering and bedrock depthBest for: Fault and structural interpretation

Techniques:

Seismic Surveys (Reflection & Refraction)

Analysis of seismic wave propagation for high-resolution subsurface mapping.

Multi-Channel Analysis of Surface Waves (MASW)

Surface wave analysis for shear wave velocity determination and soil profiling.
