I was considering resting the corners on 1/4 paving slab "pads" to deter
them from settling into the soil and shifting around, as mentioned
earlier I am considering lining them, weed membrane would be porous, so
would have to be a full waterproof membrane to stop soil within the beds
rotting them from inside out, rather than from ground-level up


Why not use paving slabs or half slabs on edge to make the beds, they
will never rot
OR a run of concrete blocks
