thunderhorse Posted August 11, 2008 Share Posted August 11, 2008 I've just punched a hole through the exterior stone wall in preparation for a 100mm polyprop waste pipe. The pipe is tough and I can't see why it shouldn't be mortared in, but would it be advisable to somehow pad it and avoid contact with the stone/mortar (or even facilitate removal in case of a fault?)Cheers Link to comment Share on other sites More sharing options...
jondeau Posted August 11, 2008 Share Posted August 11, 2008 Well I must admit I have never sleeved any soil pipes.........and I have installed a lot, never had any complaints about it either, in fact about the only thing I have ever sleeved has been copper gas and oil pipes.

Anton Redman Posted August 11, 2008 Share Posted August 11, 2008 If it were me I would put some form of lintel accross to protect it. You never know if you ever have to remove or replace it it would be a real pain if it is cemented in. Link to comment Share on other sites More sharing options...
buckdendave Posted August 11, 2008 Share Posted August 11, 2008 You can mortar it in without any concern.Dave Link to comment Share on other sites More sharing options...
BIG MAC Posted August 11, 2008 Share Posted August 11, 2008 Really depends on the make up of the wall but ideally you dont want anything bearing directly on the pipe so careful choice of location using a tie stone as a lintel may be an idea. Dont be tempted to squeeze pipe into a gap that is too tight its better to have a bit more mortar than a split pipe inside the wall. Link to comment Share on other sites More sharing options...

BIG MAC Posted August 15, 2008 Share Posted August 15, 2008 Because dear Katie its a failing of blokes generally! French soil pipe is a more brittle type of plastic in my experience also it seems a lot less UV stable . If a pipe is surrounded by a good bed of mortar the some loads will have the opportunity to pass around it. A point loading from a slighly shifted stone could crack the pipe inside the wall. I didnt spend ten years of my life fitting bogs and not learning a bit about soil pipe..........Oh how I miss it............not! Link to comment Share on other sites More sharing options...

Alane Posted August 16, 2008 Share Posted August 16, 2008 I used UK 110mm pipe as a sleeve on 100mm French pipe where it passed through a flint wall - perfect fit allowing movement/removal but not insect or rodent access. It was just lucky that I'd kept that short length of 110mm pipe from when whe had our UK house extended in 1990. I knew it would come in useful one day.

Nearly Retired (I am now) Posted August 16, 2008 Share Posted August 16, 2008 Alane,UK 110mm pipe as a sleeve on 100mm French pipe I sincerely trust the membership of this forum will permit my rather presumptious move by awarding you a top 20 place in the Best Building Tips category.
