Utility Locating in San Marcos, TX
Locating private and unmarked utilities ahead of excavation, often paired with potholing for verification. San Marcos, Texas's oil & gas, construction, telecommunications sector relies on utility locating for safe, code-compliant work around the area's 60,684-resident metro and dense underground utility footprint.
What is Utility Locating?
Utility locating combines electromagnetic detection, ground-penetrating radar, and One-Call public utility marks into a single map of what's underground at a site. Hydrovac potholing is then used to physically verify critical lines at depth. Together, locating + potholing produces the SUE (Subsurface Utility Engineering) Quality Level A data that engineers and contractors need to design and dig safely.
Key Benefits in San Marcos

- Quality Level A SUE data for engineering, design, and construction
- Single-vendor coordination — locating + potholing in one mobilization
- Reduces utility strike incident rate to near zero on located sites
- Documentation suitable for damage prevention, permits, and as-built records
