SWMBO wants some raised beds made, railway sleepers or similar.

They are going on an area which is currently slabbed with those
attractive 70's pink & yellow slabs - which will be removed.

Carpentry no problem - but should raised beds be lined with anything?

Not worried about the timber rotting - it will be pressure treated. More
moisture retention.


I would line the inner face with Terram ... keep soil in and let water
permeate.
Wood might not 'need' it, but it will keep it cleaner.

If you are in S.Wales area at any point ... I have plenty.


Or less technical just line it with a DPM poly sheet (thick black
visqueen or similar)
