Hi all, another query. We have some AIB's that - due to a damaged chimney I believe, that is allowing water ingress - keep being exposed to water; not much of it, and more around the edges from what I can see. My query is, if the AIB's are contiually exposed to water and then dry out, are they likely to become more friable? The AIB's are made from a mix of crocidolite and chrysotile. I believe that water is a good way of keeping fibres out of the air, but I also realise they are insoluble and still going to be present when it dries out. I've scoured all the HSE info I can regarding it, but I just cannot seem to find an answer to this specific query. I want some evidence so I can push ahead with getting the roof repaired; if I get some, along with recent HSE prosecutions, I'm hoping this will be enough to get the ball rolling. Thanks once again.

Another thing to consider, if being weathered and asbestos id being eroded by the water, when the water evaporates you could be left with fibres.

If water can ingress then frost can split - in other words your AIB will be loosing integrity (and fibres)
