What is a Cross Bore and How Does it Occur?
What is Cross Bore and How Does it Occur?
Per the PA 811 – “A cross bore is the intersection of an existing underground utility or underground structure by a second utility installed using trenchless technology. This results in an intersection of the utilities, compromising the integrity of either or both utility or underground structure.”
Trenchless technologies, such as directional drilling are increasingly used in urban areas to install new underground utility lines thus increasing the risk of a cross bore, which in some cases can be very dangerous as well as disruptive. With a thorough understanding of the complexities of cross boring, our expert team at EcoTech can be brought in to help identify and excavate safely and effectively with our hydro or air services thus helping to avoid significant damage to utilities and properties.
