Is it possible to lay KG pipe in gravel?

A trailer with sand might cost about 30€. Well.

That may be true. But you save renting a trailer, time, and 30 EUR. And if the gravel happens to be at the neighbor’s, who says you could have it, then I just ask. Because maybe someone here can tell me something definitive about it.

we have also laid in gravel.

Only the pipes for house entry water, electricity, internet have we laid in sand (compacted).

Thank you for the answer. Okay, what was the reason for you to use gravel instead of the usual sand?

There is a reason why a compacted sand bed is always laid during earthworks with pipes, soakaways, and similar. I would definitely not use gravel.

Yes, the question is whether it is solely the price reason
or if splitting can be life-threatening for a KG pipe?
