Hi. I've an old shed in my back garden made of pre-cast slabs bolted together and roofed with corrugated asbestos/concrete sheets. It looks like it's been there for about 40 years, at a guess. I know I need a specialist contractor to remove the asbestos roof - and any recommendations would be welcome.
However, someone recently mentioned to me the possibility that the slab walls may also have asbestos content. So I'm wondering if anyone here would happen to have a Mastermind specialist subject of "cheap and nasty building materials from 1960s-1980s" and would be able to say if this is likely. One side of the slabs (inside the shed) is smooth and dished, and looks just like ordinary plaster/concrete. The other side - outside - is slightly textured (like very small pebbles). And where there's a hole cut for a pipe, you can see the cross-section and again it looks like small pebbles embedded in concrete. It doesn't look in any way fibrous.
Does anyone recognise these slabs? Thanks!
