Hi, What is the minimum distance allowable from the bottom of a 32mm hole in a 200x60 joist. The joists to be drilled are 5ft.from the inside wall in a dormer house bathroom.
Thanks for your prompt reply.I have got 5 of these 32mm holes in my joists with a 50mm to bottom of hole.Is this ok.If not can you suggest any remedial work necessary.
If there is no major weight on the joists,then I wouldnt worry.BUT if your installing a bath on the joists then you need to brace the joists.Use the same size joist 200mm x 50mm by 1m in length then fix it to the original joist over the holes with 4 x 10mm thick bolts and dog washers.
