    Treating joists and rafters??

    Thanks Gregors, I'll go and buy some tomorrow and make sure it covers wet, dry rot and woodworm and contains biocide as you have suggested. Thanks for your help, I'll just be spraying it on all exposed timber

    Underpinning and foundations???

    Thank you very much for the advice......I spoke with North Hertfordshire building control today and spoke to one of their seveyors. He said I don't need to go down more than a foot as I'm already in the celler and my house is on chalk, already a solid substrate unlike clay. .....but he did...

    Underpinning and foundations???

    Ive recently installed an RSJ which sits on two steel posts. One of these posts sits on the top of my celler wall. I want to lower my celler floor and therefore do some underpinning. I will do this at a later date, but for now I'd like to just do the section under the steel beam load as I...

    Steel and joists

    Noseall- just seen your reply and this sounds I better idea of using a trimmer to pick up the last cut joist. You mentioned using sleeve anchors to fix the trimmer into the wall but how would I do this if the trimmer is going head on into the wall? I'd use a joist hanger for the end on...

    Steel and joists

    I've racked together joists using a nail plate. I have only done this on one side as I cannot get to the other side because of the wall. I have bought a meter length bit of wood which I will use to span the joint and bolt using M10 coach bolts and nuts. My question is should I be buying...

    Well yes....if I could extend the joist to also sit on the steel that would be great but I wasn't sure if it was sensible or if there was a practical way of joining timber to timber and extending the joist whilst still maintaining its strength and stability. Id like to hear some solutions...

    Steel and joists

    I've just looked up thunderbolts. Not used them before. My bricks are a type of brick with around 16 hollow holes in them. It's annoying because whenever I drill into my bricks they just crack and split as the hollow holes cause this to happen. Which is why I initially thought of resin and...

    Steel and joists

    Thanks for reply, the white thing is actually just the wall, but painted plaster. It looks deceiving in pic i know. Would you use chemical anchor bolts with the resin?

    Steel and joists

    I have put in a steel beam today which is bolted to two steel posts which in turn sit on pad stones under the floor. On the bottom of the steel is also welded a plate for the joist to sit on. I'm an hiding the steel within the floor so have cut the joists. However the joist closest to the...
