I set 10 fence posts in postmix/postcrete last weekend, and accidentally didn't fill the holes completely to soil level (varying from 10mm to 80mm from top of hole).
My question is - should I top it up with more postcrete to soil level? Should I fill it with shingle? Should I just put soil over it?
I'm worried about water sitting there rotting the wood away but then thought if I do more postcrete as its two separate layers it might allow water in the gap between the two concrete layers and make it worse as the water would sit in the gap rather than draining away?
Any help appreciated!
