New flue - support wall
"GB" wrote in message ... "BigWallop" wrote in message ... "GB" wrote in message ... Putting a new 100mm flue through a rather crumbly brick wall. There is a fair sized hole left over from the old boiler flue, and when I break out this old cement flue, one or two of the bricks above will be unsupported. The new flue is quite thin plastic. So, can I get something to put round the outside of this to give a bit more strength? Maybe a bit of cast iron drain pipe with a 100mm bore. Any other suggestions please? Geoff Isn't there enough room to take the new flue through the old one ? Then all you'd need to do is fill in the gap between with some sand / cement mix (mortar mix in a small sack from DIY Store). Thanks for the suggestion, but it does not really work as the old flue sloped upwards whereas the new one is horizontal. Also, we've chopped out nearly all the old flue and it was quite brittle. Still, you've got me thinking, because we have some fair sized chunks left over. Ah Ha !! Isn't there enough movement in the new flue pipe to allow it to rise at the same angle ? Pity if there isn't as this would have been ideal. If the old pipe is the same shape and will go around the new flue, then it will make things easier to fill back in though. --- http://www.basecuritysystems.no-ip.com Outgoing mail is certified Virus Free.
