    RSJ Help

    We've been having a Dorma loft conversion done, the build included the need for 5 RSJ's. One of the main issues we had been facing was freshly plastered ceilings cracking on the 1st floor, which effectively were directly below 3 of the 5 RSJ's. I decided to rip the ceilings down, I found that...

    How do I stop a cold RSJ rotting my joists?

    Hi, we're doing up a stone house, and have lots of vapour-related potential problems. Today's problem: we have an RSJ across a room, both ends in external stone walls, supporting the first floor joists.

    is RSJ correctly supported?

    Guys, I have a builder in doing some work for me. He put up an RSJ where there was previously a load bearing wall. Can you comment on the photos? I'm not 100% confident in what's been done. New RSJ spans 5 metres and also supports smaller pre-existing RSJ. Areas of concern, - Pad stone 80mm...
