I think you will have a hard time getting that out

 

[Geokhan]

Its not hard..after two or three tapping from side its easly out

Fair enough, but what is your question in relation too?

Can you try explain it a bit more with some more details.

I thought the pipes through lined channels or retaining structures were drainage pipes. Never heard of pipes used used to prevent soil heave.

have seen it done before but i prefer not to grout riprap. there are too many failure modes, such as cracking, seepage and erosion. better to use larger riprap, good bedding and no grout, even though it might cost a bit more.
