Concrete Base/Pad for Shed

kennyb3

I'm looking at upgrading our current wood shed which is too small and starting to fall apart due to rot and wood lice.

Looking at an adman shed.

I want to put it on a concrete pad, that goes out 6inches further than every side of the shed. Dont want any wet grass in contact with it even if it will be steel this time.

Is there anything else I need to know/consider other than just paying a builder to put in a level concrete pad to sit the shed on?

I assume the shed can just sit direct in the concrete pad?

Want to do it once and do it right.

Thanks

Standard best practice is to a double pour, first the slab, then the shed, then an second upstand/rebate pour inside the shed to act as a barrier to water ingress.

Some shed suppliers will sort all of this for you.

Any recommendations of those suppliers? Most seem to be only doing the shed structure itself, I'd like to have someone do the whole lot.

I think it was Shanette, but it looks like their website has been hacked so maybe stick to the phone!

I am looking at a shed from adman. They wont pour the concrete for you, but if you ask they will send you a drawing for the slab that is required.

Steeltech will do the base for you these days I believe.

I got an adman shed assembled onto a block surround filled with whacked hardcore. it's basically a subfloor built on a sloping site years ago for a wooden shed and adman fit a wooden floor . Very nice job

3x2 for shutter, 1000 gauge polythene, A142 mesh. 30n concrete. Bolt shed to concrete. No need for pouring screed on top of the concrete. Done.

That’s interesting. As in a 4inch wide x 4 inch tall up stand or a full new slab. Would it be possible to pour the upstand at the same time as the initial slab?

Unfortunately this is all second hand info, I'm not sure how deep.

Everything is possible with enough skill, but the installers my friend used did two pours.

Sorry I can't be more useful!

I think Calahonda52 did an upstand, maybe try to find his shed thread.

Steeltech's method looks fairly comprehensive;

Have asked them for details of the supplier in my area to check that's what they ll do and get a price.


Adman seem to more want to stick down a concrete base and the shed come out over it (assume this stops water ingress). I prefer their shed - the look/accessories etc. but I'm bit unsure now. I've left a message for their base supplier to see what the story is re damp proof sheet or whatever.

Anyone any thoughts? Can you just stick a steel shed on a concrete base like Adman are saying?

I'm not sure on this stuff, just want to do it once and right.

Edit: spoke to base supplier for Adman and yes they do a 1200 gauge damp proof sheet

Keen to hear what you ended up doing with respect to the base?

I’m looking into Steeltech at the moment
