Can someone tell me the reason for encasing drainage pipes in concrete when they run under an extension. Is this for structural reasons, i.e. the possible loading on the pipes. I presume its nothing to do with possible leakage ?
I am constructing a raft foundation and have found storm water drainage about 500mm below where the raft will sit. I know these pipes can stay in place, just unsure whether I need to encase them in concrete, especially as the raft will be one big lintel over this pipe, if you see what I mean.
Any help appreciated, thanks.
