How much ballast (weight) will I need to fill a space 40mm x 0.8m x 0.1m?
I need to fill a void with ballast before laying a cover, probably of slate chippings, over the top, i.e. the ballast is only to avoid using too much expensive material to fill a void. Alternative fill materials, if cheaper, would be acceptable.
