Hi all,
Just need some advice on vapour sheets as well as laying the sub-grade.
Anyway it has been raining a lot here in Melbourne (Australia) and the dirt was like rock before all this rain. The dirt underneath the gravel has become very wet and soft, it's more like Clay than dirt and this has in-turn made the gravel very wet - Pictures in link below.
My question now is does this pose a problem when laying concrete? Will a vapour sheet be needed? or can the concrete simply be poured on top of the gravel once it has been compacted.
If a vapour sheet is necessary can the concrete be poured directly onto the vapour sheet or should gravel be put on top? It will be easiest if we can just pour on top of the vapour sheet.
My friend who is doing the concreting said that a vapour sheet isn't necessary but he hasn't been in the concreting business all that long and I am a bit worried. The shed will be used as a living quarters eventually.
