Concrete coring is a process of cutting a perfectly round hole in any concrete structure, such as a floor, wall or ceiling. It is a low-noise, dust-free and non-punching method that is used for a variety of purposes in construction. It is often used to make way for new electrical conduits and cables, plumbing pipes and reinforcement, as well as to create openings for plumbing, electrical and fibre optic cables, and HVAC equipment. Concrete coring is also used to remove large quantities of concrete with minimal dust, and to strengthen the foundations of buildings by creating a concrete core.
The process of drilling or cutting concrete holes is done with a diamond cutting bit attached to a steel tube. It is an essential technique for utility penetrations and can be used for more complicated tasks such as coring specific piles and removing abdicable concrete from a property.
