Multichannel Analysis of Surface Waves (MASW)

Multichannel Analysis of Surface Waves (MASW)

Nexgen specializes in MASW, a non-invasive seismic method for evaluating subsurface stiffness and profiling shear-wave velocity. Ideal for site classification, foundation design, and ground response analysis, MASW helps mitigate geotechnical risks. With precision data and expert interpretation, we deliver actionable insights to optimize construction planning, reduce uncertainty, and enhance safety across diverse infrastructure projects.

Seismic Refraction Tomography

Seismic Refraction Tomography

Nexgen delivers SRT to generate high‑resolution 2D/3D P‑wave velocity models for near‑surface characterization. The method maps bedrock depth, weathered/fractured zones, faults, rippability, and lateral lithologic changes—informing route selection and foundation design. With dense sensor spreads, advanced inversion, and rigorous QC, we provide dependable interfaces and velocity contrasts for quarries, highways, metros, and industrial sites, reducing uncertainty, optimizing excavation, and minimizing construction risk.

Seismic Crosshole Test

Seismic Crosshole Test

Nexgen provides Seismic Crosshole Testing to obtain high‑resolution shear (Vs) and compressional (Vp) wave velocities between closely spaced boreholes. The method delivers precise layer continuity, small‑strain stiffness, and dynamic soil parameters for seismic site classification, ground improvement QA/QC, and foundation design. Our calibrated sources, synchronized sensors, and rigorous processing produce dependable velocity profiles and moduli, supporting earthquake engineering and critical infrastructure projects with confidence.
