Underground Utility Mapping is the process of identifying, locating, and documenting buried infrastructure such as water lines, gas lines, electrical cables, communication lines, and sewer systems. It provides a clearer understanding of what exists beneath a property or construction site.

Professional mapping can combine utility locating technology, GPS/GIS data, GPR scanning, and field markings to create useful records of underground infrastructure. This information helps project teams visualize utility routes and understand their approximate locations before excavation or construction begins.

Accurate utility mapping supports better project planning, reduces uncertainty, and helps contractors make informed decisions about excavation and site development. It is especially valuable when existing utility records are incomplete, outdated, or unavailable.
