Hi was wondering how much ballist and cement I would need for a 6 x 6 shed? How deep I would need to go and would you put hardcore in the bottom to start it off on? Thanks

The best option would be to fix a timber frame together to the size of your shed. Place the frame in the area you wish to put the shed. This will then be your guide to excavate. You should then dig to a depth of 6 inches and fix and level the frame with Wooden stakes around the outside. Infill with concrete, you will need 500 kilos of ballast( best to buy 1 bulk bag) and 6 bags of cement. A strong mix would be 4 ballast to 1 cement no need for hardcore just use 6inch timber for shuttering. Good luck!

Construct a timber frame the size of your shed using 6 Inch x 2 inch timber. Place the frame in the area you want to put the shed. dig a trench for the frame to a depth about of 3 inches ,so as to make the highest point of the shed base prominent to the surrounding ground . fix and level the frame with Wooden stakes around the outside. Infill the edges with the the smallest hardcore available to you . You will need approximately 500 kilos of ballast and 6 bags of cement.Infill the rest the frame with small or crushed hard core and a 5-1 mix reasonably wet to the very top and slightly beyond of your frame work .
use a straight bit off timber to screed straight on top of the two longest lengths of your framework to remove any excess cement and obtain level shed base ,then allow to dry up to 48 hrs depending on weather conditions.
