I have a boring office job, so please excuse me if this seems obvious- I've never done anything like this before.
I am creating a shed base and am following the instructions of a B&Q video on YouTube. After laying the sub base and compacting it, they suggest to use a dry mix of 9 parts sharp sand to 1 part cement. They then lay concrete slabs on top of this dry mix.
But they do not say how thick this layer of dry mix should be. Is there a thickness I should aim for?
I notice they do not compact the dry mix at all - so maybe not so thick??
