Want a fast, cost-effective, low-involvement imaging solution? GeoSonics/Vibra-Tech’s seismic refraction delivers more bang for your buck.
The seismic refraction technique induces a sound wave into the subsurface and measures the velocity of sound at intervals along a traverse line to obtain depths and velocities of various subsurface strata. The velocity of the strata provides an indication of the ease with which the material can be excavated. One advantage of the seismic refraction technique is that it allows you to determine subsurface conditions inexpensively over large general areas. Typical refraction survey applications include depth to bedrock; depth to water table; dig, rip, or blast assessment; fault location; mineral exploration; sand and gravel reserve assessment; and subsurface sinkhole and pinnacle location.
