The seismic refraction technique is an advanced geophysical method that is applied for routine investigation of subsurface ground conditions by using surface-sourced seismic waves. Data acquired with the help of this technique on site is further computer processed and interpreted to attain models of the seismic velocity and layer thickness of the subsurface ground structure. We are one of the best Seismic Refraction Survey Services in India.

THE TECHNIQUE

The seismic waves disseminate downward through the ground till the time they are reflected or refracted off subsurface layers. Refracted waves are identified by arrays of 24 or 48 geophones spaced at regular intervals of 1–10 meters, based on the required depth penetration of the survey. Sources are placed at each end of the geophone array to generate forward and reverse wave arrivals along with the array. Use of additional sources may intermediate positions for entirely covering at all geophone positions. If you are looking for Seismic Refraction Survey Services then you are at the right place.
