Hello having a chimney built its a concrete linear with vermiculite infill to chimney stack read on the bag the vermicuite comes in that it can be used with cement mix for infill the bricky however says that on all the work hes ever done on chimneys they always pour the vermiculite straight in the brickys a good bloke and i believe thats how it can be done as well but wondered if any one.
