Clean hardcore (Kinnerton LD8)

UPDATE: Sorry but these stones are NOT suitable for a small rockery or wall building only hard-core

As you will see from the photo I have a stone wall that I have lowered and remove some of the smaller broken/delaminated stones.
I have 5 "animal feed" bags of mostly clean stones. Any mud will be minimal and wash off.
These stones would be great for a small foundation BUT not for a rockery or wall.
They will easily go in the boot of a car.
Any question please ask
