Core Drilling

Definition

Core drilling is the process of drilling that extracts a cylindrical sample of concrete, rock, or soil. It is sometimes used to install pipe or conduit in or through an existing concrete or masonry wall.

Purpose

The purpose of core drilling is to obtain samples for testing and analysis or to create precise holes in concrete or masonry structures for the installation of utilities or other structural needs.

Examples of Use

• In construction, core drilling is used to create holes for plumbing or electrical conduits in concrete walls or floors.
• Geological surveys use core drilling to extract soil and rock samples for analysis.
• Engineers use core drilling to test the strength and composition of existing concrete structures.

Related Terms

• Boring: The process of creating holes in a material, typically less precise than core drilling.
• Sample Extraction: The process of obtaining samples from a material for testing purposes.
• Percussion Drilling: A method of drilling that uses repeated impacts to break material and create a hole.

Notes

Core drilling requires specialized equipment and expertise to ensure that the extracted core and the resulting hole are accurate and meet the project requirements. Safety measures are essential to protect workers from dust and debris.
