Concrete coring is typically performed using a diamond coring bit. The bit is attached to a drill rig and rotated at high speed. Water is sprayed onto the bit to cool it and prevent the concrete from becoming too hot.

The core sample is extracted from the concrete and then transported to a laboratory for testing. The tests that are performed on the core sample will vary depending on the specific purpose of the coring.

Concrete coring can be used to assess the quality of concrete in a variety of structures, including bridges, buildings, and pavements. It can also be used to investigate defects in concrete, such as cracks, voids, and delaminations.

Concrete coring is a valuable tool for geotechnical and structural engineers. It can provide valuable information about the condition of concrete structures and help to ensure their safety and durability.
