Seismic refraction surveys for rippability and depth to rock

Before excavation or blasting, knowing where hard rock starts can save a lot of money. I run seismic refraction surveys across Ohio and neighbouring states to map depth to bedrock and estimate rippability. - Survey design and field acquisition - Tomographic processing - Velocity profiles and rippability classes - Report with cross sections One field day typically covers 500–800 m of line.
