for me at all or will it become waterlogged.

KK.
Well the jury is still out on copper rings and tape (since when it gets tarnished it is no longer viable, and it's expensive).
However ... do you have WD40 in your shed? I did a trial this year on 6 pots of hostas and only one got attacked by the wealth of snails that live here. You have to spray once a month but it has proved to be far more successful than that 'garlic liquid' potion I tried as well - all plants well eaten so clearly my snails like a bit of garlic!
The makers of WD40 also mention its slug deterrent odour.
I think the cheapest and probably best solution to your pond requirement is either a plastic storage crate , available in DIY stores for c. £5, or a heavy duty crate used by house movers, usually blue and much stronger than the storage crate, cost about £10.
It is in the ground so cannot be seen, is not expensive, and will tide you over for two or three years.

Try sawdust or wet vermiculite around the base of your plants and petroleum jelly round the base and top of your containers...its stick or slip for mr slug.
