What timber for shed base and floor

sarah_id1

I have a concrete shed base already build in my garden. I suppose I still need a wooden base and wooden floor as given in this link "Choose your Floor" and "Choose your Base option".

I was looking for the right timber to build this in B & Q but still not sure what timber to pick as it would need to be long lasting in all weather conditions.

If you've got concrete down, just remember that water is the killer of wood, so make sure you waterproof and seal the base so it doesn't come from underneath.

Plywood or OSB will work fine for the floor

EDIT: On that link, Plywood looks to be the economy option at a guess. The premium one will be easier to fit and look better. As long as it doesn't get wet and is supported well enough, it shouldn't matter too much

The bearers need to tannalised wood. You may find railway sleepers are the better option (they aren't actually railway sleepers, but that's name they are sold under). As for the floor - are you buying a shed from website link? If so, i would choose the tongue and groove floor.

Put the bearers on 3 high engineering bricks, any wood is going to rot even hard wood. That's if you want the shed to stand for more than 50 years.

I built my shed base bearers from pressure treated wood, then stapled a damp proof (plastic sheet) over the bearers, then used OSB on top of that to make the floor.

We bought a shed from them. Quite a large one. Went for one of their higher end sheds. But it was really poor quality. Everything was cut back to the bare minimum. The wood and every support was as thin as possible.

Thankfully we moved house not too long after we got it. Not sure if it is still standing. They are cheap for a reason.

Thanks for the suggestions.

So it would be pressure treated bearer with OSB timber board over it.

To prolong the life of the bearer I liked the idea of having engineering bricks underneath, but it may raise the height a bit too much! and the bigger issue is movement over long time as it cant be nailed in!
