I have an old, approx 5", soil pipe that runs below a solid slab that I need to fill/block/seal before laying insulation etc. I can only see 4" expanding plugs at Toolstation which aren't big enough.
The other end of the pipe connects to the mains sewerage pipe below ground level, which I will eventually disconnect when it's dug out.
For now, I need a quick/easy way to seal the pipe (opposed to the current plastic bag rammed down it).
Will wire wool + expanding foam to the trick?
