Concrete volume

[surreygooner]

Hi,

I'm putting down a concrete base for a patio and just want to double check my figures. The area is 11sqm and I'm putting down 100mm bed so I've worked out I need 80 x 25kg bags of ballest and 20 x 25k bags of cement.

Just don't want to be short over the weekend!

That's about right.

Wouldn't it be cheaper to get a couple of dumper bags and make up the remainder in 25kg bags?

Quite right...

Thanks for the comment, as this is a terraced house and i've laid a tiled and heated floor in the kitchen, I didn't want to barrow materials through the house.

Thanks
