Pleasing colour. What do you use it for?

Depending on the size of the chunks, most of it is the bluemetal road that people dive on, but in this case it was for a subsoil drain underneath the future building so that it doesn’t get mould creeping up the walls.

The big chunks(40mm) are the ballast under railway lines, and the even bigger chunks (100mm) are what you chuck into a drainage ditch to stop erosion.

Versatile resource.
