DEPTH TO BEDROCK SURVEYS
Earth Scan has conducted numerous projects where depth to bedrock has been an important consideration in designing pipeline routes, HDD river crossings, and also as a way to explore for gravels or determine overburden. Surveys can be conducted through most natural environments with no line preparation and no environmental impact. Several kilometers a day can be acquired in difficult terrains with greater production possible in open areas.
The GPR section below shows coarse boulders and a deep paleochannel down to 27 meters in depth.
The section below is excellent data profiling two stages of sand and gravel deposition over a plunging bedrock horizon. Note the highly fractured bedrock high, as well as the fracture zone that represents risk to a directionally drilled pipe installation.
