Rock Coring

In bedrock or solid rock , wire-line rock coring collects bedrock cores for engineering and geological study.

A diamond bit attached to a core barrel is lowered into the hole, and core rods of the same size are attached to reach the bedrock starting point. Rock core samples are obtained by removing the inner barrel assembly from the core barrel of the drill rod using an overshot retriever attached to a drill rig winch.

Typical uses include foundation investigations, material sources, rock cut investigations and general rock coring of native bedrock substrates to obtain geotechnical data and samples.
