Im just looking for some quick advice regarding using oak railway sleepers for a retaining wall



Idea is to have a wall similar to this... ...



The height difference of my garden between the lower ground and upper ground level is 40cm, (dimensions of the sleepers are 10x20cm), so 2 sleepers would be in contact with the soil, then I intend on having 2 sleepers on top, making the overall height of the wall 80cm (4 sleepers) tall.

Would untreated oak railway sleepers be ok?

Would a plastic weed membrane be recommended behind the wall against the soil?

What would the best method be to make it a sturdy as possible?

A few pictures I've just taken of the area they'll be sitting up against...



And the sleepers...



Would these be ok to have put up without any treatment?

The builder I'm having the garden done has said he'll put in a solid concrete base, stick concrete posts around the back, and (he never said how) attached the sleepers to the posts.
He also mentioned having steel rods going through the centre of the sleepers, right through into the concrete base.

Timing will be an issue now with treating them, they're due to be fitted tomorrow.

I asked the opinion of a few different people, some in the know, and they all seem pretty adamant, if it's oak wood then it's not necessary.... Though looking at them, they absolutely look like they'd need some sort of treatment for them to last more than afew years...

I'll end up putting some sort of vanish/oil coating on the fronts, but obviously once they're fitted getting to the back won't he possible

You have time. I have treated wood and used it the following day. Protecting the bit you can see is not as important (at this stage) is protecting the bits you can't
Is there any specific product you could recommend?

I would have thought not treating them would be a big error... Why did you not buy treated ones?
I was under/given the impression that because its oak, they wouldn't need treating, though reading some of the posts, im getting the feeling that's not the case?

I could as an act of desperation try delaying getting them fitted, and give me tomorrow to put some sort of treatment on them...

Is there any specific brand/type that anyone could recommend?
