Question

Can i use crumbled concrete as gravel under new concrete?

Answer 1

Irv is on target.

I have used very small pieces but I use my plate compactor.I do use recyled concrete as a perfered base,but that is crushed.You would be much safer for a lasting job to just dispose otherwise.

Thanks Irv

Answer 2

absolutely.  No problems with that and a good place to get rid of it.

Answer 3

Provided that it's thoroughly broken up, raked and tamped level, yes.

If it's otherwise, you will have problems.

Good place to get rid of it!
