garden shed base

[wulbert2001]

does anyone know how much sand cement and aggrigate ill need for a 10ftx12ft base.

320 is the magic number. 320 divided by any depth (in inches) will give you an "x" factor to divide into your square footage.
Example: The form is 120 square feet and is 4 feet deep. Four feet is 48". 320 ? 48 = 6.7 as your factor.
120 ? 6.7 = 17.9 yards of concrete needed.

or

just lay 30 2x2 paving stones and build shed quick and cheap

classic
four feet deep sounds very deep mate do ya not mean 4 inches

everything is metric now mate 10 feet is 3.1 m
12 feet is 3.7m

3.7 x 3.1 = 11.5 m squared

1.2 m cubed of cement should do ya from a cement company save ya all the hassle of mixing it
this will give ya a floor ten cm high
so ya could make the frame for the floors from 4x2 and just pour the concrete in and level it easily
