A Non-Standard Repair for Masonry Chimney

[Rob From Wisconsin]

I remembered several years ago reading about technique
that was infrequently used to repair damaged/cracked
masonry chimneys. It involved filling the flue with a thermal
cement material & pulling a bell-shaped device through it,
making it into a circular flue packed w/ this special cement.
I don't remember all the details beyond that....
Anyone else out there shed some light/experience with this???

Still a lot of them done. A great way to reline a chimney. Here is one outfit on the web:

Just search for "poured chimney liner".

Thanks Bart!!
I'm pretty sure this is what they did on the masonry chimney of the
house we just bought. It may not be the exact type. Some heat can
still be felt on the cinder block rising through our house, but even after
a day's worth of hot fires, it is barely warm to the touch.....

Funny you should bring this up. I just researched it for my neighbor. The method I found is Ahrens Chimney Technique:

I take it these liners are reinforced with some special fibers? I would think it would crack over time like concrete, but I guess its different. Seems like a good option to redo a chimney. I seen it done on this old house.
