    Hi all,

    Are any of the pre-mix concrete (just add water types) any good? I have a couple of loose paving slabs and no sharp sand/cement to hand so thought I could give one of these a go to get things do quickly instead of doing the mix myself.

    Or am I trying to cut a corner that isn't worth cutting?

    Thanks,
    TFT

    I've never used the pre-mixed bags, but concrete usually has gravel/stones within it (adding strength). If the bed you're laying your slabs on is only thin, a stone may stick up out of the bed and cause a slab to rock or crack. so unless the concrete bed is to be quite deep (at least a couple of inches, which may be unnecessary), it you might consider using a pre-mixed mortar (which is smoother consistency with no gravel/stone).
    Alternatively, buy a few bags of sharp sand and a bag of portland cement - dry mix the two thoroughly at a ratio of 6:1 then add a little water.
