House connection electric / electricity / telephone

Hello,

the last utility provider (electricity) was here and installed the house connection. In doing so, he extended the underground cable and pulled it into the house.

When asked whether the underground cable should be additionally protected with a protective conduit, he said that was not necessary. I should refill the lines with sand and then backfill the trench normally with gravel.

Only the waterworks wrapped their PE pipe with a cheap corrugated pipe.

Is that no longer necessary nowadays? The cables and pipes that go directly from the ground into the trench are not even surrounded by sand.

I am a bit afraid to close the trench like this, and later a pipe might get damaged and everything would have to be dug up again.

The answer is rock-free soil. That is all one needs today.

The ground where the cables and pipes come out is not free of stones...

refill with sand

Is the important statement... nothing more is needed.

Additionally, you would have to order pipes around it before installation and at your own expense. I have also had an empty conduit laid in case another cable connection is needed (after the development area is further developed).

Hello,

I also have a question about this.
Do you all have these expensive branch connections to protect the entries against water? Or is there a more affordable solution?
