Concrete coring, or concrete drilling, is the process of extracting a concrete cylinder from a structure. It is used in a variety of fields, such as plumbing, electrical, drainage, manholes, air conditioning and structural testing. Concrete drilling is the process of cutting or drilling concrete, whether it's ceilings, walls or floors. It is not typically used for DIY projects such as drilling small holes in a wall for furniture or hangings.
The process of drilling or cutting concrete floors, walls, and ceilings is called coring. Circular cuts in walls and slabs are made by a process called concrete coring and are used in construction for many reasons. These openings are created to provide spaces for conduits, cables and other utilities. Special attention must be paid to limit vibrations when coring is carried out in buildings where sensitive equipment has already been installed.
Concrete coring uses a diamond cutting drill to cut a perfect round hole in any concrete structure: in a floor, wall or ceiling. An undisturbed concrete core can also be used by engineers to test the strength and soundness of any concrete structure. Reverse drilling is the drilling of cores upside down through the underside of a concrete structure and is often used in applications where access from above is restricted. Concrete cutting is a set of techniques used in the professional field to cut large concrete slabs, rectangles or squares.
Another use of concrete core drilling is to take sample cores from poured concrete so that quality control companies can test its strength. A homeowner may need to use a concrete core drilling service supplied by a furnace drilling company.
