What's the cheapest sort of panel boards (6x4 ideally) that we can use as
flooring for a newly installed metal shed.

As there's no effective barrier to prevent water seeping in from its
concrete slab, we're thinking of using a pond liner as a waterproof layer
and cut down couple of 6x 4 panels to use as a flooring material.

What's the best type to use on cost/resilience basis?
OSB (what used to be Sterling Board)
MDF (thick or thin)
Marine ply
Chipboard.

I'm not really up on new board technology so any guidance would be
appreciated. The shed will be used for storing tools / garden stuff.

Cheers all

mdf is useless when wet, but not sure if you would actually need and
damp proof layer and boards, seal/mastic the shed sides to the base is
all I would have done

So is chipboard. But if it's going to be wet, any of them will rot.

Given the way the base is assembled, I can't guarantee that running sealant
around the base would be 100% reliable, so the idea of a liner with boards
appeals.

I probably will run sealant around anyway.

Any more thoughts on boards? What's the cheapest per m^2 boarding?

Maybe not a good advertisement, since mine's been damp for the last 5+
years*, but 18mm OSB/Sterling board has survived remarkably well.



* I really *should* do something about it, but the amount of junk I've
got stored makes the job tiresome.

None of the above.

I had the same problem with a metal shed & made a slatted floor from treated
roofing battens. Keeps stuff off the concrete base, allows it to drain.

Lay 50mm x 50mm floor beams (pressure treated) on the concrete. Tack strips
of DPC along the top face of the beams. Screw 18mm OSB down onto them. The
DPC will prevent water ingress from the beams and the under-floor space
should provide sufficient ventilation to keep things dry enough.

I wouldn't use the a pond liner or any waterproof sheet across the floor
area. If water does get in it will be trapped there.

Don't try and keep it perfectly dry, make sure it's ventilated, i.e.
have space between the wooden flooring and the cement.

I've just used some wbp ply to replace a rotting shed floor (soil and
sand had spoilt the ventilation), but I'm not sure it's necessarily
the best material, just easy to work with.

Yes, definitely, I've posted a similar comment. Air space to let it
dry is what's needed.

Which is why a raised wooden floor is ventilated.

I would put down 50mm polystyrene board and then 20mm Chipboard over that.

Thanks for all the tips.
In the end, I ignored the suggestions about keeping the underfloor
ventilated by raising the floor - the headroom isn't brilliant any way, and
losing another 2 or 3 inches didn't appeal.
We've put down 2 layers of pond liner pulled up to at provide at least 4cm
depth all round and 11mm OSB on top of that.
We'll see how things go on over the winter, and if the OSB seems to be
getting damp in any way we'll re-consider.

Thanks all.

If I understand that correctly, you have made a shallow pond and put the
shed in it. You are now hoping that the rain running down the sides of
the shed will not fill the pond up. Even if the liner is pulled up at
the edges *inside* the shed, any condensation will be trapped.

sounds like it :-)
not one reply thought the pond liner was a good idea yet the OP went
along with that idea ,
lets ask for help and as long as its what you want to hear its ok if not
ignore the answers,OP must be a manager eh :-)

You misunderstood :-) Of course the liner is inside the shed - anything else
would be daft!

Any condensation on the walls will run down the walls and will be 'outside'
the liner.

There is a fair amount of ventilation from under the eaves so condensation
shouldn't be a significant problem

Any condensation on anything stored in the shed will drip onto the
floor, and accumulate. It better be dry.

Ask yourself why no-one else ever does this.
