Evening all.
Im getting a high security heavy duty shed for the back garden. The instructions say to fit it on a level base 3.1m x 2.5m x minimum 50mm thick.
The shed weighs almost half a ton without the contents.
In the garden where i want it to be built, there is top soil around 25cm deep, and then an old concrete slab 10cm thick (not sure if it has any rebar).
What would be the best way to build a foundation for the shed? Ive considered the following:
Hardcore and then slabs - wondering if this will be robust enough?
Pure concrete slab with rebar on top of the current one - thinking this is a bit of an overkill, costly, and heavy.
Hardcore with concrete slab on top of the current concrete slab - is it ok to put hardcore on top of concrete? Will it compress?
Any thoughts or ideas?
Thanks
