Hello everyone,

While working on some foundation projects and excavating soil, I encountered the following underground pipes:

Pipe Depth https://drive.google.com/file/d/1i0B3RQ6l5EzKJHzuZUbCEnRsfmOwYoCK/view?usp=sharing

There are two pipes situated next to each other at a depth of approximately 250mm. The auger scratched the surface of the pipes, revealing a black outer plastic layer and a shiny white metal-like material underneath.

There are no leaks; the pipes are simply wet from the weather. However, I am unable to determine if these pipes are for gas, water, or electricity.

Can anyone help identify these pipes? Is it safe to proceed with concreting over them?

Thanks
 
You ought to upload the photos directly into the thread, we shouldn't have to open external links even if they seem legit.
 
Did the piling company get you to sign a waver so that any damage to services will be at your cost?
 
They won't open for me. But depending on the diameter it sounds like armoured cable.

Two cables identical cables, suggests loop in and loop back out to next door. Check where the supply cables enter your cutout, near your meter - if you see two cables there.
