Hi. I'm laying flags in my front garden adjacent to the house. I've layed down stones (sandstone) that have come up from my garden (I live on stony ground) - for the purpose of a hardcore base. I've got a 8x8 Roughneck tamper and I've managed to compact the stones. Now, this compaction is not to a professional standard, I mean the compaction does not match what would be obtained by a large roller machine. On top of the hardcore I'm laying down a 1 inch layer of sharp sand. At the moment the sand is damp, not dry.
Q1: So, given that the compaction is not to a professional standard, would it be advisable to lay down a membrane on top of the hardcore and lay the sand upon that?
Q2: Is it OK to lay the flags on damp sand, or should it be dry?
Thank you. Rich
