I have a new soil stack run externally.
The holes that were drilled in the wall for the 40mm waste pipe were drilled slightly to big.
Shall I use some cement on the outside and then some foam on the inside?
The inside will not be seen as there will be kitchen units on the covering it but I just want to keep out the draughts and damper slight movement.
I have some of that quick drying cement mix that you just add water to will this be OK to use as I do not want to use anything that can would attack the plastic pipe and make it brittle View media item 7214
