In the spring I will be building a new shed/play house for my kids and it will be built on an old hard-standing that needs new concrete.
The area I am working on is 8 foot x 10 foot and 4" deep. I believe it equates to 0.99 cu. yds.
I already have 20 bags of ballast (25kg bags) and 10 bags of Cement (25kg bags) from a previously cancelled project.
Does anyone have any idea of how much more of each I will need to fill the above area to the top.
I have had different answers from Wickes, B&Q and a couple of Building Merchants and I am wanting to get the rest of the materials on site well in advance of starting but I do not want to buy more than I need.
I would be eternally grateful to anyone who can answer this.
Thank You in advance.
