A cross bore is the intersection of underground utilities.  A cross bore can occur between any underground utilities- electric, communication, sewer or gas. It's most dangerous when a gas line intersects a sewer. 

Most cross bore inspection projects highlight high-risk areas with an average of two to three cross bores per mile of sewer line. As trenchless technology installation methods continue to evolve, the demand for our multi-level inspection and assessments help mitigate risks and allow your business to operate as safely and efficiently as possible.
