Clay drain pipe on concrete bed - Adding junction

[StuM]

Hi All,

Firstly, thanks to all at Paving Expert for an excellent resource!

We're doing some extending and alteration of our house which is resulting in having to alter some of the original drainage - laid in 1951. Basically, we have two new SVPs that will need to be joined in to clay pipe.

The original plan was to install a new plastic IC in line - as per the superb photo-guide on this site. However, unlike the pipe in that photo-guide, ours is sitting on a 250mm bed of concrete, haunched up the sides.

I've had a search around, but was unable to find an answer to.... what is the best way to get a clean end on such a pipe to allow fitting of a rubber coupling? I'm guessing that it is going to be painful?

The drain is shared with the neighbours, so I need it to be out of action for the least time possible.

Thanks in advance for any tips/advice/sympathy etc..

Regards,
Stu

Use a small breaker, hilti, or similar. You can also try an hammer and pointed chisel, cold chisel etc. Start away from the pipe and slowly work towards it chipping away, taking great care not to crack/break the pipe. The concrete shouldn't be that hard after such a long time.

Thanks Sean. So slowly, slowly is the key.

Will let you know how it goes.
