What is Ground Penetrating Radar?

Ground penetrating radar pushes short radio pulses into the ground from a wheeled or handheld antenna and records what reflects back off boundaries between materials. Because it reads a change in material rather than a current on a wire, it reaches the targets electromagnetic locating cannot: PVC and HDPE with no tracer wire, clay tile, concrete pipe, septic and storage tanks, vaults, and voids. It is also the instrument that shows what is NOT on any map, since it images whatever is down there rather than only the lines someone thought to record.

What Paso Robles Clients Get Out of It

• Finds non-conductive targets — plastic, clay, concrete — that carry no traceable signal
• Images tanks, vaults, voids, and washouts as well as pipe
• Confirms depth of cover over a line that is already marked
• Works over pavement, slabs, and finished surfaces without opening them
• Pairs with electromagnetic locating so the two methods cover each other's blind spots

Ground Penetrating Radar in Paso Robles Conditions

Paso Robles sits in a mediterranean climate. Local ground: Clay, Sandy loam, Alluvial. Soil conductivity is the variable that decides how much of a locate radar can contribute, because conductive ground absorbs the radar pulse instead of reflecting it. Primary industries — oil & gas, construction — drive steady demand for ground penetrating radar across the San Luis Obispo County area.

DigAlert (Southern CA) / USA North 811 (811) requires 2 business days of advance notice before any excavation in California. That notification is free and it is separate from ground penetrating radar: it brings out the member facility owners to mark the lines they own, and stops at the meter or the right-of-way. Wait for every member to respond before ground is opened.

When Paso Robles Clients Use Ground Penetrating Radar

• Locating plastic water and gas services past the meter
• Finding clay tile and concrete sewer laterals with no map
• Mapping abandoned or unrecorded lines before excavation
• Void, washout, and sinkhole detection under pavement and slabs
• Underground storage tank, septic tank, and vault location
• Confirming depth of cover over an existing utility
• Scanning for irrigation mains and drip laterals on acreage

What a Ground Penetrating Radar Quote in Paso Robles Depends On

Locating is quoted per job rather than off a rate card, because the work is a search and a search scales with the site rather than with the clock. On a Paso Robles job, the things that move the number are how much ground has to be covered, how many targets are in play, whether there are meters, valves, risers, or panels a transmitter can be clipped to, what the lines are made of, what the local ground (clay, sandy loam, alluvial) does to the instruments, and whether you need surface marks or a record you keep.
