Does crushed granite passageway crack? ...
Answers: Are you actually discussion about crushed granite, or are you chitchat about paving setts made from reconstituted crushed granite (i.e. crushed granite stuck wager on together again)?
If the former, then no, it can't crack - it's be crushed.
If the latter, then it will be ok as long as it's installed properly, on a compacted dais, in accordance beside manufacturer's instructions.
Shouldn't this be in the trick section
