ᐅ Backfilling behind L-shaped blocks / corner blocks

Hey everyone,

does anyone have good experience with installing corner stones?

I'm unsure about the backfilling:

the stones are being installed without drainage, so is it necessary or advisable to backfill with gravel anyway?

My understanding is that this would allow water to seep down, but then not drain well since there is no drainage system.

Wouldn't it be more sensible to backfill directly with soil in this case?

Best regards

Using gravel provides the ground with a bit more buffering capacity than soil. However, that has nothing to do with proper drainage. If water doesn’t infiltrate well or at all in your area, you need a plan, because the water must go somewhere. Either you have an open water management system and create suitable trenches or swales, or you have a closed water management system and install a drainage system. There is no middle ground.

Of course, you can also do nothing and just backfill. In that case, I kindly ask you to post pictures of your new "pool" here after the next heavy rain. 😎

Thank you first for your reply.

The plan now is to seal the joints between the stones not with bitumen, but with a sandbox fleece.
If there is really heavy rain, the water that does not drain into the ground can flow away.

Can anyone bear the sight when this happens? I have a case like this in my neighborhood; after autumn and winter, the stones look completely filthy. Not even crystal-clear spring water would seep through here ;-)

That's true, of course, but it doesn't matter because there are bushes in front of the stones, and I can't see anything there anyway.

Technically speaking, this shouldn't cause any water to accumulate, right?
Would you still fill in with gravel behind it?

I'm a bit unsure about this.

Best regards
