Seismic Refraction Surveys
Our company conducts seismic refraction surveys worldwide to determine subsurface characteristics such as the thickness and depth of geologic layers. Seismic refraction surveys can map depth to bedrock, clay layers, or the water table.
Seismic refraction surveys can be used for mining investigations, rippability surveys, and foundation studies, and can be used at hazardous waste sites. Our field crew can set up the seismic refraction survey equipment quickly and start obtaining subsurface information immediately. The seismic refraction survey crew can provide preliminary in-field answers and can print preliminary cross sections.
We use the GeoMetrics SmartSeis seismograph for its seismic refraction surveys. The SmartSeis is a high resolution, fully automatic seismograph.
Some typical uses for a seismic refraction survey include:
GeoMetrics SmartSeis Seismograph
In-field and final cross sections obtained on the SmartSeis Seismograph during a seismic refraction survey
Ground Penetrating Radar Surveys
We also can conduct GPR surveys to investigate the subsurface soils and rock. GPR surveys are fast and cost efficient.
