Slit the bag to let the contents spill onto pavement where it will be dead easy to shovel off, 10-15 barrows and your done.
Don't have a wheelbarrow. I do have a shovel and a bucket though.
I will have a go at this over the weekend. I am a skinny tiny bloke. I was thinking of shifting it over a month. But, then again, if only I had know that the driver wouldn't have a crane!
