Huraah! The Building Control inspector was happy with my RSJ, so I now have to shim it with steel shims - he wasn't happy with slate, the old fashioned way - and cement it in.
Two questions. Does anyone sell steel shims or do I have to make my own? I can if I have to.
Secondly, do I use an ordinary 3:1 mix or something stronger?
Thanks
John D.
