Can anyone tell me what these are?

New fence installed today and on one side of the gravel boards it's all like this. The rest is smooth like it should be.

They're the remnants of air bubbles that formed on the surface of the wet concrete as it dried rapidly in the mould.

Will they go away? They look awful

No, they're concrete. Once it's set, it's set

Oh no. Should I contact the people? Would you? It's all over 2 boards and 3 posts, not just a little bit

Anyone?

Looks like bubbles from when the mix was setting (when the boards were made), but don't know why it would have happened. The bloke installing probably saw it as structurally OK, so may not have realised the appearance would bother you.

Apparently it's normal. Iv looked on google and a few posts saying about etiquette with neighbours and who gets the "rough" side when installing a fence.
I'm going to see if I can sand it down, it's really bugging me and strangely making my skin crawl arghhhh

Can you grow something in front of it?

If you're responsible for the fence, you show the best side to the neighbour.

That's why those fencing panels are so popular - they look the same both sides.

This should have a trypophobia warning. Eep.
