Bridging Subsurface Imaging with Engineering Parameters for Reliable Design and Risk Reduction
Reduce Uncertainty Between Data and Design
Traditional site investigations often rely on limited borehole data, leaving large uncertainty between investigation points. Geophysical surveys provide continuous subsurface imaging—but without engineering interpretation, their value remains underutilized.
At GeophysicsPro, we integrate geophysical data with geotechnical parameters, transforming subsurface information into engineering-ready models that directly support design, risk assessment, and construction decisions.

Why Integrate Geophysics with Geotechnical Investigation?
Boreholes provide accurate but limited point data
Geophysics provides continuous spatial coverage
Integration reduces uncertainty between boreholes
Enables interpolation of engineering properties across the site
Improves reliability of design models
👉 The result: better decisions with fewer unknowns
What We Integrate
We combine multiple datasets into a unified subsurface model:
Geophysical Data
Electrical resistivity (ERT/IP)
Shear wave velocity (MASW)
Compressional velocity (SRT)
Ground Penetrating Radar (GPR)
Geotechnical Data
Borehole logs and lithology
Standard Penetration Test (SPT)
Laboratory test results
Rock Quality Designation (RQD)
From Geophysics to Engineering Parameters
One of our core strengths is converting geophysical measurements into engineering-relevant parameters.
Shear Wave Velocity (Vs) → Soil Stiffness
Determines deformation behavior
Used in seismic design (Vs30)
Correlates with soil density and compaction
Vp & Vs → Elastic Moduli
From seismic data, we derive:
Poisson’s ratio (ν)
Shear modulus (G)
Young’s modulus (E)
Bulk modulus (K)
👉 These parameters are essential for:
Settlement analysis
Foundation design
Numerical modeling
Resistivity → Material & Fluid Conditions
Differentiates clay, sand, and rock
Identifies groundwater zones
Detects weak or saturated layers

Frequently Asked Questions (FAQ)
Why not rely only on boreholes?
Boreholes provide accurate data at specific points but cannot capture variability between locations. Integration with geophysics fills these gaps.
Is geophysical data reliable for engineering design?
Yes, when properly calibrated with borehole and laboratory data, geophysical results significantly enhance engineering models.
Can this reduce investigation costs?
Yes. Integrated surveys often reduce the number of boreholes required while improving overall understanding.
What is the main benefit of integration?
It transforms fragmented data into a continuous, interpretable subsurface model.

A notable lateral variation is observed between 40m and 70m distance, where a deeper "pocket" of lower modulus material may indicate a localized zone of higher porosity or soil saturation
