    RSJ lintel calculations?

    Won't the beam only be supporting the equivalent of one bedroom floor (half of one and half of the other)? Also half of the total ceiling area as long as the ceiling joists are supported on the bedroom dividing wall.

    Overboarding

    Thanks jbonding, I have not seen any signs of damp so I think I will go with Hardwall as I have used it before and was happy with the results. Just out of curiosity is there any reason for using sand and cement other than cost? Many thanks again
