Hello everyone,

Normally, KG pipes should be embedded in sand underground. What confuses me, however, is that drainage pipes are supposed to be embedded in gravel (e.g. 22/32), even though the drainage pipes appear to be much less stable than KG pipes (e.g. KG-2000).

Why is that?

Best regards

The gravel in a drainage is supposed to direct the water into the pipes.

And the sand around the [KG Rohre] is supposed to protect the pipes from damage caused by stones etc.

Thank you. So far so clear. But, can't the gravel damage the drainage pipe, but a KG pipe can?

Gravel will not damage a [KG pipe] either...

No idea if it’s allowed, but I think the pipes should be able to withstand it.

Why risk a fracture? Is it going to fail because of a few shovels of sand? And what kind of load is to be expected on the topsoil? Sidewalk or [Speditionshof]? I might possibly still live with the sidewalk, but the latter is definitely too risky.
