Our Services

We use advanced technology and proven techniques to accurately locate underground utilities and subsurface features — protecting your crew, your project, and existing infrastructure.

Underground Utility Locating

Electromagnetic locating to pinpoint gas, electric, water, sewer, telecom, and fiber lines before excavation. We identify depth and horizontal position so you can dig safely and stay compliant.

Concrete Scanning / GPR

Ground penetrating radar to locate rebar, post-tension cables, conduits, and voids within concrete slabs. Essential before core drilling, cutting, or anchoring into any concrete structure.

Private Utility Marking

Locate and mark private utilities on your property that 811 / DigAlert doesn't cover — including private water, sewer, gas, and electrical lines from the meter to the structure.

Built on Accuracy & Accountability

When you call us, you talk to the person doing the work. No call center. No runaround. Just straight answers and reliable results.

Years in the Field

A decade of hands-on utility locating experience across California. We've seen the easy jobs and the tricky ones — and we show up ready for both.

811

Beyond the Call

DigAlert marks public utility lines, but private lines are your responsibility. That's where we come in — filling the gap that 811 doesn't cover.
