I've just had my new garden shed delivered and before I put it up I'd like to make sure the base/floor will be ok.

The shed is an 8x6 ex-display one and the wooden floor has 6 joists running along the length of the shed. The shed will be on a paved area of the garden but I was wondering if it would be worth putting something under the joists to help stop them rotting.
I was thinking along the lines of getting a roll of damp proof course from Screwfix and tacking it to the bottom of the joists to keep them away from the surface water.
Is it worth doing this?

Also, what's the best thing to treat the wood with?

I'd purchase some tantalised battens and sit the shed on them. That way, if anything rots, will be easy to replace.

Yup - the place you got the shed from might be able to supply 6 foot treated bearers to rest the shed on.

I built some short piers all round from two breeze blocks on their sides (per pier), then rested the bearers on those and built the shed up from there.

That gives enough room for a terrier to get under after rats if they are a problem (my shed is in a line of sheds used for storing horse feed etc.)

Think like water would.

Lift the shed on either treated timber or fence posts or blocks or bricks along the line of the shed joists. Roll out some DPC (you could use any old polythene if you keep it outof sunlight) between the shed joists and whatever you rest them on. If it extends past the end of the shed, drop it downwards so any water will run off.

One other tip, make sure the base is dead level, if its not you will struggle later.

This: http://www.thompsonsweatherproofing.co.uk/products...

Empty a couple of inches into a bucket and stand the timbers on end for a day, do the same for the other ends.
Spray/brush the remainder of the timbers.
Dont fart about with dps or membrane, it traps moisture.
If you want to be a real tart about it blackjack (bitumen) the timbers.
