thermolite told me that they still offer a structural guarantee if their cracks are vertical.
i used that glue system on my own house with the big format blocks.
i have 1 metre deep foundations in virgin soil.
i had a 9 metre wall with three seperate expansion joints when i didnt need them. the blocks were 7nm blocks
i had the thrmolite rep and one of their technical staff watching me as i laid the blocks as i was their first private customer.
it is my house, i did all the work. every screw is stainless steel, all the wall ties are stainless and way over specified. everything is over specified because im a fussy git.
all of the block walls split vertically !
as you can imagine i was not impressed.
thermolite said it was normal.
i cut off the render and put on a plastic/fibre glass mesh and re-rendered.
that was several years ago and there has not been a problem since.
my concern was that water would get behind the old render and blow it.
i was ****ed like you are but i dont think it is a big worry at all.
