shed build - foundation advice

[stephen low]

Guys

Just chasing some advice for my small shed transformation.

I had a simple 3 x 3m garden shed that became chockers with assorted crap and I started looking for a replacement alternative a long while ago.

Found a modest fleabay special sometime back and am gearing up to install the 8 x 4m replacement soon. Its a standard steel frame, hardwood beam construction and colourbond sheet affair. Frames bolt to uprights that need to be pre-concreted into place.

Have planned on pouring a slab that is 150mm thick but with an additional 50mm beam depth, some 300mm inwards from the outside edge, ie an edge beam of 200mm thickness.

Am thinking down the track the shed might house a car hence the edge beam treatment but do want to put in re-inforcement too.

I am thinking just 1 layer of reo but what sizing do you guys suggest?

The old 3 x 3 was just 100mm thick and without reo and performed very well, including resistance to being chopped up - ha

After suggestes lads please.

Mininum F62, F72 better.

A 100mm slab will be fine for a car or light truck.
150mm for a truck.

Thanks guys

Tomcat I assume just one layer for a small slab like this - yes?

And for the limited variance in cost I'd go the F72 anyway.

I agree with the F72 mesh and gal if near coast. If you are thinking of hoist....you might need pad footings to support hoist. Better to provide now than later.

Youre all over it, many years ago all we ever used was F62 in house slabs, F72 now and F82 in raft slabs, 100 mil thick plenty 25 mpa.

Only 25 mpa needed in this application?
