Underground Utility Locating in San Diego
Electromagnetic locating and ground penetrating radar to map water, sewer, gas and conduit runs across coastal fill and decomposed granite before anyone breaks ground.
- GPR through concrete and asphalt
- EM tracing on metallic and traced lines
- Depth estimates and surface marking
- Pre-excavation site sketches
Non-invasive locating
Four technologies, one square foot of certainty before anyone touches your slab.
- Acoustic
- Correlated listening on pressurized lines
- Thermal
- Hot-side imaging through finished floors
- Tracer gas
- Inert helium/nitrogen for silent leaks
- Pressure
- Zone isolation to confirm the failing loop
Dispatch & scheduling
(619) 923 - 0033Know what's under the site before the excavator arrives
Public 811 marks stop at the meter. Everything past that — irrigation mains, pool plumbing, private sewer laterals, landscape lighting conduit, propane runs and secondary electrical — is the property owner's responsibility, and it's what actually gets hit.
San Diego ground conditions
Decomposed granite through the inland valleys returns clean radar signal but shifts backfill over time, so as-builts drift from reality. Coastal sand and lagoon fill along the Oceanside–Carlsbad–Encinitas corridor hold moisture that attenuates GPR at depth, which is why we pair radar with active electromagnetic tracing rather than relying on one method.
Deliverable
Surface marking in standard APWA colors, estimated depths, and a site sketch you can hand to your contractor or attach to a permit package. Add water leak detection or gas leak detection to the same visit when a located line is already suspect.
What we locate
Leak detection services in San Diego
Every call starts with electronic locating — acoustic, thermal, tracer gas and pressure isolation — so the repair in San Diego is surgical instead of exploratory.
Water Leak Detection
Acoustic correlation, thermal imaging and tracer gas to pinpoint pressurized water line failures inside San Diego walls, ceilings and service laterals — no exploratory demolition.
