Underground services . There are supposed to be colour codes but it’s unclear if used correctly here . R means detected using the radio wave function on the CAT ( well it did 2 years ago when I did my last EUSR certificate) I do the refresh next week
Zap, hiss and spit.
It’s some form of Elvish. I can’t read it.
The red is Power, hence the P next to it and it leads to the streetlight. The orange has a R next to it so Radio, normally picks up power cables but also BT, Water if metal pipe, etc.
The long line indicates the location and. direction of cable a C over the line with the line going through it creating a capital E but curvy stands for electric. An R will mean radio frequency on the CAT (cable avoidance tool) but we would use 2 dots either side of the long line to make a long ÷
That pavement will never be that smooth again!
Usually means there’s going to be some works going on, or as that patching suggests, work has been done already and they did a CAT and Genny scan to make sure they don’t strike any mains during the works! Think someone has already explained all the colours and letters pretty well.
Try fingers. But Hole.
I read a article about these kind of markings once and I said that there are regional variations kind of like local dialects
Here’s the full guide on service location colours.
Red: Electric power lines, cables, and conduits.
Yellow: Gas, oil, steam, petroleum, or other flammable materials.
Blue: Potable (drinking) water.
Green: Sewers and drain lines.
Orange: Communications, alarm, or signal lines.
Purple: Reclaimed water, irrigation, and slurry lines.
Pink: Temporary survey markings, or unidentified or unknown services.
White: Proposed excavation limits or route.
Red means electricity, yellow means gas I believe.
The yellow ones that look like a P or an R are junctions in the pipes
Results of scanning technology to mark sevices beneath
Typically, such markings are done, when you have a ground penetrating radar survey. It’s good for detecting voids, ie ducting and empty pipeware. Iron pipeware used to be easier to find, especially using a genny to generate a signal down the metal pipe or wire. MDPE for gas and water makes that impossible, unless its a big mains or road crossing and they’ve put a a tracer wire in. I don’t think there’s a standard for squiggles, but the person who needs to understand it is the one digging the hole, by hand if its near a service..
The different colours are related to different services and different symbols meaning different types of fixtures etc, manholes, wire runs etc
Well, it’s an older code, but it checks out:
“We cannot get out.
We cannot get out.
They have taken the bridge and second hall. Frar and Loni and Nali fell there… Five days ago… The pool is up to the wall at Westgate.
The Watcher in the Water took Oin.
We cannot get out.
The end comes… drums, drums in the deep.
They are coming.”

I don’t know, but I’d keep a tight hold on my dog if I were you. xx.
Markings on where things run underneath. Stuff like water, electricity, internet etc.

I’m not a roadworker, but I always presumed (or was perhaps told) it was marking off underground services locations.
“These are the end times”
“He is arisen”
“Take some time for biscuits”
Not sure that’s completely accurate 🤔
“They’re watching. They’re onto us. They know we’re going to dig a hole and then do nothing for weeks. We better hide”
The bbc did an article on this a few years ago https://www.bbc.co.uk/news/magazine-25915468.amp

Utilities survey spray marks.
