- in this video I run through the process of elimination in order to try and locate a pipe that is in the area but that no offset is available and no surface feature is visible.

Geelong Cable Locations are the experts to call when you need to know where underground cables and pipes are buried.
We service Geelong, Melbourne and Country Victoria.
We offer:
- Electromagnetic Field Locating (also known as digital locating, or just cable locating)
- Ground Penetrating Radar
- Non-Destructive Digging (also known as hydro excavation, or vacuum excavation, or even just known as NDD)
- Concrete scanning
- Acoustic locating (perfect for locating poly water pipes)
- Drafting
- GPS plotting
- Project management
We’ve been in business since 1998, making us one of the oldest and most experienced service locating companies in Victoria.
Our manager Ben Minutoli was the first in Victoria to obtain his Dial Before You Dig certification and, to date, we’re still the only company in Victoria to have multiple technicians within the company who are DBYD certified (if you don't know, that’s the highest level of certification for a locator in Australia).
Great video keep them coming. I'm in the United States and I am also a locator
Cheers, thanks buddy.
Up in western Canada, I am also a locator. What size is your GPR, I have an LMX 100 Sensors and Software? 250 MHz.
Hi Brian, good to meet you.
This radar here I am using is a GSSI and it has a 400 MHz antenna on it.
I am looking to see if GPR can help me. I have a neighbor who has a bunch of buried plastic 4 inch gutter downspout pipes on my property, buried by the previous owner. The neighbor isn't trying too hard to find them and I need to locate any before they become the basis of a claim on my land. Will a GPR like this work for locating 4 inch plastic buried pipes for downspout drainage? They are buried about 6 inches. Also, I see that ditch in the video -- I have a ditch just like tis separating the street and driveway from area to search and need to know if a GPR operator would be able to get their equipment across such an obstacle to the search location? It's about 2 to 3 feet wide.
Hi Don, I have just done Somme googling to see what downspouts are as we call them a different name in Australia.
If I understand this right it is simply the drainage pipes that go from your neighbours to the street or the lowest point and your saying it goes through your property.
They should be pretty simple to locate.
The way I do it when customers call me and ask me to do it over here is by pushing a cctv camera up the pipe from the house to where they exit. Or the other way round of access is easier.
The reason I use a cctv push camera is so that I can see what the pipe itself is like this way I can let the homeowner know if there are any cracks where water can be leaking. But also so I can see if there are any interconnecting pipes that also need to be located.
I then walk along and locate the cable from the cctv that is now in the pipe.
This is a lot more accurate than GPR and it is a lot quicker.
Of course if it doesn't work then yes GPR is the next technique I use.
What country are you in? Did you want me to try and refer you to someone that might be able to do this for you or are you ok to look someone up?
Regards Ben
@@GeelongCableLocations Thanks Ben. My problem is the neighbor isn't cooperating. He doesn't want me to find his plastic roof gutter drain pipes. They run 150 feet from his house to a stream on my property. I found one when the lady next door was looking for them because they didn't even know exactly where they were when they bought the house. She was sneaking around my property looking nonchalant with a weed whacker. Now they are protecting them from me and harassing me whenever I enter that part of my property. So I cant do a trace from the origin, their house -- because they wont let me. Any contractors I call out will be interrogated by them (they are very entitled). Since posting this comment I requested a GR quote and the GRP operator said GPR will not work in my area due to the presence of many vines, roots, water underground as it is drainage and he would need to trace a wire from the house like you descried. So I have been using a hand soil probe which does not work very well as it hits hard soil, rocks and roots and doesn't really give you any feedback if you hit a plastic pipe. I found the second one from looking at aerial photos where there was some old pictures of colored lines in the grass. Now to look for more, I dont know what to do. I dont want them to steal my beloved property!! THank you Ben
Dam, yeah he is right, GPR would struggle to find them in those conditions.
Who actually owns the pipes? What happens if you dug through the area with an trencher, would you have to pay to fix them, or could you tell your neighbour to remove these pipes that you have just damaged while you were trying to dig a trench in your property?
What does the local municipalities say about it?
I know the neighbor doesn't want to cooperate, but if you tell them you are digging in the area and you don't want to damage the pipes on them, then maybe they will give you full access.
Just an idea :)
Good luck
@@GeelongCableLocations The neighbor owns the pipes. Good idea. I'll have to come up with a good pretext for digging a trench in this wooded area.
Hello everyone.
hello
Is the GPR good to reach down 8 meters ? . And how to calibrate it ?
Hi юнас путин, no this radar can't go 8 meters deep.
Generally I can get around 1 maybe 2 meters deep with this one, depending on what the soil conditions are like.
You can get different antennas that can go a lot deeper, but you can't use those to look for underground services. Instead they use those to find different soil conditions, or if you are looking for ruins in ancient lost cities and stuff like that.
I just detected a void . I understood that it is a tunnel because it has specific dimontions
congratulations.
