Hi all, having never used cement/concrete underground, I would appreciate any advice?
Having to cement boulders back in to whence they came to fill a hole.
Do you just use standard 4:1 cement or is a concrete mix better?
They won't be near water but obviously the cave is a damp environment so anything special need to be done?
Many thanks in advance, Mark
