What is Coring?

Coring is the name for the process of cutting small, surgical circular holes through a hard surface to access the infrastructure beneath it. This is largely used for utility operations but can also be beneficial for consumers and the public. Some of the benefits for consumers include less disruption and noise, faster repair times, fewer and shorter service interruptions, and reduced traffic blockages. 

18” diameter cores are the industry standard, but 24” diameter cores are also used when the application requires it. 


The Benefits of Keyhole Technology for Coring

Keyhole technology for coring has many benefits. It is much friendlier for the environment and also easier on the crews. It saves a substantial amount of money for both the community and utility companies when compared to traditional methods.
