GPR Locating in Ocala

We Find All Sorts of Things Underground: Metal or Plastic

In Ocala the limestone can start right at the surface, sinkholes are a real concern, and on big properties almost every line is private. GPR Bros has already done GPR locating here, scanning and marking work areas before the digging starts. Across Ocala and Marion County we find the metal and plastic lines 811 won't mark, scan concrete before you cut, find water leaks, locate electrical faults, run pipe cameras, and sweep for buried oil tanks.

GPR Locating Across Marion County

How GPR Locating Works

Every GPR Bros locate follows the same three steps: you tell us about the job, we scan the site and mark every line we find right on the ground, and you get the paperwork.

Step 01

Contact

Tell us the site and what you’re planning: digging, boring, coring, building. We figure out which methods the job needs and send the right tech with the right gear, same day when it’s urgent.

Step 02

Locate

Our tech sweeps the site with ground penetrating radar plus electromagnetic tracing, finds every line and target we can detect, metal or plastic, and marks it right on the ground in APWA colors with paint and flags.

Step 03

Deliver

You get paint and flags on site, a PDF report with depth estimates within 24 hours, and GPS-referenced KMZ maps or CAD overlays if your team needs them. A record you can actually build from.

We Find What 811 and Metal Detectors Miss

Florida law says you call 811 at least two full business days before you dig, and the ticket is good for 30 days. The utilities then come out and mark their lines. The catch is what they don’t mark. In Sunshine 811’s own words, “member utilities only mark the facilities they own.” Everything past the meter is yours: the water line to the building, the sewer lateral, irrigation, landscape and parking-lot lighting, power to a shed, sign or gate, gas to a pool heater or grill, fire lines, and lines running between buildings.

Those misses add up. Florida logged 37,275 underground utility damages in 2025, at an estimated $4.2 billion in total cost. The average gas or electric line hit runs about $147,000 to $151,000 once everything is counted, and the repair itself is only about 6% of what a hit really costs nationwide. The rest is downtime, delays and everything that follows.

No single tool finds everything. Radar sees plastic, concrete and metal, but wet clay, muck and salt water cut down how deep it reaches, and it can’t see past a metal line sitting on top of another one. An electromagnetic locator follows metal pipe and wire very precisely, but it can’t find plastic or fiber unless a tracer wire was buried with it. We bring both, and use whichever one the ground and the line call for.

How We Find What's Underground

Ground Penetrating Radar

Ground Penetrating Radar (GPR)

Our core tool. GPR fires radar pulses into the ground and reads what bounces back, so it picks up plastic, PVC, concrete, and voids that metal-only locators walk right over. No metal required.

Electromagnetic Tracing

Electromagnetic Tracing (EM)

For metal lines, we put a signal on the utility and follow its path and depth: active mode when we can connect to a line directly, passive mode to pick up live power and telecom.

Acoustic Leak Detection

Acoustic Leak Detection

For pressurized water lines we listen. Ground microphones and correlators amplify the sound of escaping water to pinpoint the leak before anyone digs.

CCTV Pipe Cameras

CCTV Pipe Inspection

When we need to see inside a line, we push a camera through it, confirming pipe material and condition and showing exactly where a sewer or storm line runs and where it's failing.

What We Locate With GPR

GPR Bros runs seven services off one core skill: finding what’s underground and telling you exactly where it is. Ground penetrating radar is the through-line, backed by electromagnetic tracing, acoustic sensing, and CCTV where the job calls for it.

Private utility line locating icon

Utility Locating

Water, sewer, gas, electric, telecom, and the private lines past the meter that 811 never marks. Radar finds plastic and metal alike.

Concrete scanning icon

Concrete Scanning

Rebar, post-tension cables, and conduit inside slabs and walls. We mark safe cut zones before your saw or core bit touches the concrete.

Electromagnetic signal tracing icon

Leak Detection

We trace pressurized water lines, then walk them with ground microphones to pinpoint the breach, so you dig one hole, not ten.

Sonde and duct rod tracing icon

Fault Locating

Underground electrical fault? We trace the cable and isolate the failure point so the repair crew digs only where they need to.

Buried metal detection icon

Oil Tank Detection

We sweep with radar and magnetometry to find buried oil tanks, cisterns, and piping before a sale, closing, or dig.

Video pipe inspection camera icon

Video Pipe Inspection

We push CCTV cameras through sewer laterals and storm drains to find cracks, roots, bellies, and blockages from the inside.

Void & Sinkhole Detection

GPR finds voids, sinkholes, and buried structures that don't show on any drawing, before they become a problem.

If your looking for a reliable company with great customer service and quality work! GPR Bros are the way to go!! Highly recommended!

★★★★★August 2026

​GPR Bros delivered top-tier service! 811 only marks public utilities, so we hired GPR Bros for private locating before excavating. Their tech arrived on time, used advanced GPR equipment, and precisely mapped out all underground utilities on-site. Fast, accurate, and professional—they saved us from costly line damage. Highly recommend!

GPR BROS is the only place I will ever get GPR Scanning from going forward. they took care of us and beyond. And all the scans were very accurate a special thanks to Aaron

★★★★★March 2026

We used the Ground Penetrating Radar services to locate our underground utilities in our HOA community. It was done in a timely manner from scheduling to service it could not have gone better.

Types of Lines and Targets We Locate

GPR Bros marks all located utilities with paint and flags following the APWA Uniform Color Code. Your excavation crew sees exactly what type of infrastructure runs beneath their equipment before breaking ground.

How to Get Ready for Your Locate

A little prep makes the locate faster and the marks more useful. Here’s what helps:

  1. Put in your 811 ticket first. The utilities mark what they own, and we find what they leave off.
  2. Mark the dig area in white paint or flags, so everyone is looking at the same spot.
  3. Tell us what you’re doing and how deep: a fence, a pool, a bore, a trench, a core.
  4. Send whatever plans you have: site plans, as-builts, irrigation maps. Old drawings help even when they’re wrong.
  5. Give us access to meters, cleanouts, valve boxes, the irrigation controller and the electric panel. That’s where we hook onto metal lines to trace them.
  6. Keep the marks visible. If they get scraped off, or the ticket runs past 30 days, get them re-marked before you dig.
  7. Within 24 inches of any mark, Florida law calls for extra care, like hand digging or vacuum excavation, not the bucket.
On-Site Paint and Flag Marking

Every job gets marked with APWA color-coded paint and flags to prevent damage and increase work safety. We use water-based paint that makes semi-permanent marks visible throughout your project. Dirt and grass areas get flagged. We adapt our methods to ensure no existing structure gets damaged during mark-out.

Written Job Report

Our reports document everything: technician name, time on site, utility types located, depth estimates, methods used, obstructions encountered, and any other findings from the investigation. You get a complete written record of what we found and how we found it.

Photographic Documentation

Photos document our work and provide permanent reference points for years to come. We photograph utility marks alongside permanent landscape features so locations can be verified long after paint fades. Every report includes a Dropbox link with all project images.

Satellite Overlay Maps

Upon request, GPR Bros provides satellite imagery overlaid with visual illustration of all utilities located, depths, and other job-relevant information. Maps show exactly where gas lines, water mains, electric, sewer, and telecom run across your site.

GPS Survey Files for CAD Integration

All GPR Bros technicians carry geo-satellite receivers. Upon request, we perform a basic GPS survey and deliver KMZ and KML files you can import directly into your project software or CAD systems.

About Ocala

Ocala is horse country that keeps growing. Farms, barns, and long private runs of water and power sit next to new commercial sites and subdivisions, and on big properties most of the lines are private, so 811 won't mark them.

We've scanned and marked sites in Ocala, including a paved and landscaped work area off Gainesville Road.

Ground Conditions in Ocala

UF/IFAS describes the limestone under Marion County as sitting anywhere from right at the surface to about 50 feet down. The aquifer here is open to the surface, so slightly acidic rain soaks straight into the rock and slowly dissolves it into cracks, crevices, and sinkholes near the surface.

Up top, the soils run from deep, dry sand to clay-rich ground. The sandy soils common around the city rate high for radar; the clayey ones, some with water about 6 inches down, cut it short. On a farm or a big lot that can change across a single property, so we read the ground as we go and mark both the lines and any soft or disturbed spots worth a second look before you set posts or pour.

What’s Under the Streets in Ocala

Ocala runs most of its own utilities. The city handles water and sewer, with more than 145 lift stations, and its electric utility, in business since 1898, serves more than 59,000 customers over 1,200 miles of line. The city also owns 781 miles of fiber. Two city plants send reclaimed water to the Wetland Recharge Park, and Peoples Gas runs the gas.

In June 2022, an 18-inch sewer force main broke on SR 464 and spilled 595,950 gallons, and in 2023 the city spent $645,000 replacing a corroded force main on SE 17th Street. Force mains run under pressure, so when one breaks, it spills fast. If your trench or bore is going anywhere near one, you want its exact line and depth before you start. That's the job.

We work across Ocala and Marion County, from downtown to the farms northwest of town, plus nearby Belleview, Dunnellon, and Silver Springs.

Frequently Asked Questions

Common questions from Ocala contractors, engineers, and property owners about GPR locating.

Can you locate the lines on a farm or large property?

Yes. On big properties most of the lines are private: wells, water runs to barns, power to outbuildings, irrigation, and fence charger wiring. We trace and scan them and mark them on the ground so posts and trenches miss them.

Radar can show loose or sunken soil and some voids near the surface, which is useful screening on a site with limestone this close to the top. It isn't a full sinkhole investigation. If the scan shows something that needs a deeper look, we tell you so you can bring in the right engineer.

Yes. Clay soaks up the radar signal, so on clay-rich ground the scan doesn't reach as deep as it does in sand. We tell you the depth we got and trace metal and wired lines past that point.
