Material membrane 50cm below driveway

[Egnaro]

Not sure where to put this, so I do apologise if it's in the wrong section.

 

Due to a soil pipe, I'm hand digging a post hole for some driveway gates. Around 50cm down, I've come across what looks to be some kind of material membrane. Can anyone tell me what this could be (photo attached).

Was it maybe covering the soil pipe at one time and slipped when backfilling?

Probably something like Terram. Used to separate soil from stone surrounding the pipe

@Egnaro  If it’s Terram / weed barrier it’s in an odd place but should be inconsequential in terms of what you’re doing.

 

Weed barrier is usually to do exactly that when landscaping, eg stop organics from growing.

 

Somebody may have put this over the pipe as a marker, just a bit odd due to how close it is to the pipe.

 

If it’s all backfilled with concrete then you’ll get the same effect, but you should wrap the pipe of concrete will be meeting / encompassing it, to allow movement.

It runs under the soil pipe and appears to extend in all directions. The path is around 90cm wide followed by the outer wall of the property. The was none, or indeed anything wrapped around the soil pipe except an odd chunk of concrete and the chalk /limestone filling.

Odd, but not a life changing issue. 
 

The only reason to wrap this pipe is if your intended concrete work is going to come into contact with it, or encapsulate it.

I have some Geotextile laying around, so will wrap it in that with some pea shingle (once I've dug around the pipe).
