Soil touching against Fencing

I am making a raised garden bed on either side of my garden using sleepers
Once I fill them up with soil,some of the soil will be against my garden fences
What would I do to protect the fences from the moisture of the soil and also the weight(if that's an issue)
Thanks

    How deep will the soil be in the beds?  Is your fence wood or plastic/vinyl?

    It's wooden 
    I think about 20cm deep

    I'll be adding another 15cm of topsoil

    I would build a back to your raised bed with more sleepers.. or better yet, concrete blocks like these..
    That fence looks like it will need replaced in the not-to-distant future.. and looks like it belongs to your neighbor (?).  Place concrete blocks in a row about five inches from the fence, and use that as the back boarder of your raised bed.  You can get concrete toppers for the blocks, if you don't like the looks of the holes.. or a board.  They are cheap, not going to rot, and can be removed easy if the fence needs replaced.

    The fence is part of a party wall but my neighbour unfortunately is somebody not worth dealing with!!
    I have a narrow garden hence the garden bed is only 60cm wide
    I beleive putting the concrete blocks would make it even more narrower
    That would be same issue with sleepers plus the cost of the sleepers  
    Are there any other options 
    The cheaper the better
    How would putting damp proof membrane between soil and fence work?

    You could use concrete 'gravel boards', intended for the bottom of fencing panels.  Something like these:
    If you drive some 50x50mm wooden stakes in between the fence and the gravel boards, they will be strong enough to support the weight of the soil.  Scaffold planks supported the same way would also work, but would need lining to stop them rotting after a few years.

    A trowel in the hand is worth a thousand lost under a bush.

    Thanks for that 
    Scaffolding boards sounds cheaper 
    Lining would mean damp proof membrane 
    I am planning on changing the fence after a few years so do you think just allowing the soil to sit against fence would not even last that much

    The fence will start bowing out under the weight - wet soil is very, very heavy, even if only 20cm deep and even good close-board fencing like yours isn't strong enough.  Aslo, any damp getting between the liner and fence panels will rot them very quickly - it's just not worth the risk.
