GPR Locating in Orlando

We Find All Sorts of Things Underground: Metal or Plastic

Orlando keeps pouring concrete, and every new tenant wants to core it. GPR Bros does concrete scanning and GPR locating in Orlando, finding rebar, post-tension cable, and conduit in the slab, plus the underground lines past the meter that 811 won't mark. Central Florida's sandy ground is good for radar, and we tell you plainly where clay or soft spots change that. Leak detection, fault locating, pipe cameras, and oil tank sweeps are on the truck too.

GPR Locating and Concrete Scanning Across Central Florida

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.

Technician feeding a sewer inspection camera into a drain

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.

Seven Services, One Call

Utility locating, concrete scanning, leak detection, fault locating, oil tank sweeps, pipe cameras and void detection. One crew covers all of it, so you make one call instead of four. Call 954-873-6000.

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.

Ground penetrating radar cart icon

Void & Sinkhole Detection

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

​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!

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.

Local Knowledge · Orlando

About Orlando

Orlando never stops building. Hotels, distribution centers, hospitals, apartments, and offices all go up in concrete, and then get cored and cut again for every change. Each cut can hit rebar, post-tension cable, or live conduit inside the slab.

Cutting a post-tension cable is dangerous and expensive. We scan the slab first, find what's in it, and mark safe zones to core or cut right on the concrete.

Ground Conditions in Orlando

Orlando sits on sand over the limestone of the Floridan Aquifer, and that rock is why Central Florida gets sinkholes. In May 1981, a sinkhole in nearby Winter Park opened about 300 feet wide and 80 feet deep when the ground dropped into a cavity in the limestone. Most of the city's soils are sandy, with the water table anywhere from about 2 and a half to 5 feet down, and some areas carry a loamy, clay-rich layer underneath.

Sand is good news for radar: federal soil surveys rate most of Orlando's sandy ground high or very high for GPR, so we can usually see a long way down. Where the clay layer shows up, the signal gets cut short, and we tell you that instead of calling the ground clear. Radar can also pick up loose or disturbed soil that's worth a closer look before you set a slab or heavy equipment on it.

What’s Under the Streets in Orlando

In Orlando, OUC supplies water across about 200 square miles from seven treatment plants that draw on the Lower Floridan Aquifer, and it supplies the power across much of the city. About 68% of OUC's electric lines are already underground. The city runs the sewer, and Peoples Gas runs the gas. Reclaimed water is available in some parts of town, and Water Conserv II has been piping treated water nearly 20 miles out to citrus groves since 1986.

On October 2, 2022, right after Hurricane Ian, a 36-inch sewer force main broke, affecting Audubon Park, Mills 50, College Park and the Lake Ivanhoe area. The city is now replacing Lift Station 2, which is more than 80 years old, for $19.5 million. A lot of Orlando's buried pipe is old, and a lot of its power is buried right next to it. With two thirds of OUC's lines underground, a trench or bore in Orlando has a good chance of crossing live power.

We work across Orlando, including Downtown, Lake Nona, Baldwin Park, College Park, MetroWest, and the tourist corridor, plus nearby Winter Park, Kissimmee, Sanford, and Winter Garden.

Frequently Asked Questions

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

Can you scan a hotel or warehouse slab before we core it?

Yes. We scan the slab, find rebar, post-tension cables, and conduit, and mark safe spots to core or cut right on the concrete. It's a short visit that keeps a drill from hitting something expensive.

It depends on the slab, its thickness, and how much steel is in it. If something limits the scan, we tell you on site instead of guessing.

Radar can show loose, sagging, or disturbed soil and some open voids, because they bounce the signal back differently from solid ground. In Orlando's sand it can often see well below the surface. It can't promise a site is sinkhole-free, and if something needs a deeper look, we say so.

OUC marks its own electric and water lines when you call 811, up to the meter. Anything past that, like site lighting, irrigation, gate power, or lines between buildings, belongs to the property and won't be marked. That's what we find.
