Determine the number of bags of premix cement you will need. If you have a cubic yard, or 27 cubic feet, you will need 40 to 2077kg. bags. The amount of water you will need depends on the actual type of cement you are choosing. Bags of premix cement (36.3kg.) range from £2 to £4, as of 2011, depending on where you live and the brand you are purchasing.
