How much would a concrete slab cost to lay?

Get 12x25kg bags of cement and a tonne of ballast so price those up you probably have some left over that you might need for the future where I come from a bag of cement is a fiver and ballast too is cheap enough and a mixer would be less than 20 a day so it would be cheaper than a truck but there may be some guys who have their own smaller trucks to do smaller deliveries in your area a quick look at the yellow pages might throw up a few for ya ok,good luck.
