Seismic is the measurement of wave’s velocity through and around the earth’s surface, recorded in meters per second (m/s). Different substrates permit slow or fast propagation of sound waves.
This method along with Reflection and MASW is used to detect any changes in-ground type, bedrock, voids, sinkholes, shafts, ground stiffness, and soil strength.
Seismic refraction is commonly used for the detailed study of the shallow subsurface (less than 30 meters).
A proven track record of working along roads and railway’s projects.
Applications:
Lithological and structural interfaces
The level of groundwater table
Landslide areas, potential slip surfaces
Boundaries between different weathering zones in the rock mass
Unfractured solid bedrock and rock rippability in quarries
