Foundation question....
Discussion
Morning all,
I'm putting up a shed at some stage and need a bit of advice...Now to most this should be pretty straight forward but I appear to be struggling. Now, if I want to put down a foundation of 6ft x 8ft x 3ins deep, how much "stuff" do I need to order??!! I was planning on buying a dry mix, which I'm told will go off with a bit of water/damp.
Thanks for any advice!

Why not level the site, blind with sharp sand, and slab? Then, if ever you feel the need to reposition the shed, twill be easy.
Thanks all...Max Factor, honestly
Not a bad idea this. Don't like the idea of wet cement.....Bit tricky for an office boy. The sand is a good idea. I trust it won't "move"??!!!

Many sheds don't actually need a solid slab foundation , as they have wooden floors.
You may be able to just position the shed's floor joists on small concrete "pad" foundations , which need much less concrete ( all the pads will need to be at the same level )
I just did the sharp sand and slabs trick for mine

If the subsoil wants to move theres nothing that you can do to stop it moving (within certain financial constraints). But for a shed, the above is perfectly acceptable.

you could even use a few levelled-up breeze blocks on some comapcted sand or harcore to support the floor. ( much less mess than concrete)alfaman said:

This is the one......Nine breeze blocks strategically placed, and held in place by a dry mix...Ok?!!
However, would the floor of the shed be ok to hold the weight of my bike (165kg)?!
Thanks again.

Thats the fella.
Or about .33 cubic metre?
Or just over a third of a tonne.
The Density of concrete is on average 2400 kg/m3, therefore 0.33m3 will be approximately 0.8 of a tonne. (800kg)
How much mass does the water add?
I did a foundation for my kiddies play house last weekend and worked out that i needed .5 cumeter of concrete, the chap at the builders merchants said that I'd need half a tonne of sand and gravel mix for that, and lo and behold, he was right.
What ive done with shed foundation/supports,is mark out the area and dig equal holes in that area big enough to take half or a full concrete block laid flat then lay the block on a bed of sand...level these all in...then lay the shed bottm on to double check level and also checking give in floor....if there is too much give in one area add another block accordingly.
A little tip before laying the shed bottom on permanatly is to staple/pin some waterproof plastic where wood meets block to help stop rot.
