Base for SummerHouse

[Brianatmersea]

Hi
Need to do concrete base for above approx. 3 m*3m by 4ins. deep roughly.
Is there a way to work out bags of cement needed & amount of ballast.
Will have to be done by hand.
Many Thanks
Brian

Thanks for link,I was a few bags of cement out
Is it ok to put base on top of ground,rather then digging down,as will struggle to get rid of soil ?
Cheers Brian

Not really, you need to get to inert subsoil, this may be closer than you think! You've got to consider the building weight, and how it will move the ground below it, or how the ground will support the building without shifting, top soil cant do this. Think how you can utilize this soil on site if poss...poinenot
