Thanks Thomas that's what I'm leaning towards. Maybe throw a couple of biggies under the wall if they seem to be missing when I take the thing down

It's going to be rebuilt not repaired or patched up.. so...  Given all that. Who thinks I need a poured concrete foundation?

There's nothing too huge no

Hi Glenn. I was planning on using nhl3.5 for the rebuild

Did you read what you actually typed?
There seems to be something missing.
I think your self appointed advisors need to be grilled for their experience in wall building  and their depth of knowledge ton the subject.
I have experience, but I would need to see the wall and have some local experience on hand to help me.
The issue of water getting inside the wall, that is a key point.

To explain further. This is not a boundary wall it is the wall of an outbuilding. Not a particularly important one but one I would like to keep all the same. The site is on a slope and this is the highest building. Connected to it is a larger workshop of the same material. It is both higher and deeper it you get my drift. I will attach pictures tomorrow..
When I say th wall has been moving and flexing I'm assuming that is the case in a wall built of stone and clay. Not the issue that brought it down. The water got into the wall through broken roof tiles. My fault for not patching it up in time but I have only had the place 6 months and there are a lot of roofs to repair amongst a long list of other jobs.. thanks for replies

I'm about to rebuild a stone wall that has tumbled in the December rains. The wall is I'm guessing at least 100 year old and built with clay mortar. The reason the wall fell was water entering the wall through the top where there was a broken tile, expanding and washing out the clay inside..
As far as I can see there is no problem with the foundation (literally just dug down to subsoil and build there on). However people have advised to remove the whole wall, pour a concrete foundation and build th new wall on that. My worry is that it only one wall connecting other outbuilding that have been flexing with the moving ground and a slab of rigid concrete may disturb the equilibrium?🤔 Moreover if it is an expense I can do without paying all the better!
The wall btw is not huge around 9m long and not quite 2m high..

I wouldn't want to call it anything other than what it is. If I have an electrical fire or a burst pipe I don't want my insurance company coming around and voiding a claim because of the rhm..
In any case I've spoken with them and provided some links for them to check out. They seem unfazed which is encouraging. I plan to build it this spring or early summer time and will provide any updates regarding the insurance situation that may be of use or interest to anybody.

Thanks for quick replies!
Yes I did mention it was a masonry heater (also not too well known here).  With somewhat of a language barrier and the unknown nature of the rhm we agreed the best thing to do would be to email some details so they can get a grip of what I'm planning.. even if it is just to say they won't insure it and have an exemption on the policy to say everything but the rmh is covered..

Hi I was wondering if anybody has a link to some concise information about rocket mass heaters? I am planning to build one in my home in South west France this spring but first my insurers would like to know what exactly it is they are dealing with. There is very little information available in the French language that I could find but any links I can translate for them. Also if there are any people out there who have had one passed by their insurers or building inspectors I would be interested to hear their experiences.
Many thanks in advance!
