Hello, I'm currently looking at a project where I wish to re-locate the bathroom to the first floor. In order to gain some height in the room I want to move it I am looking at removing the existing floor joists and installing new ones. I have researched on the NHBC website and have decided to use C24 75*147mm timber for the joists. It also stated about embedding them 100mm into existing masonry, however reading online it maybe easier and more accurate to line the joists up using a Ledger/Wall plate using same dimension joist timber. What I cannot seem to find are °What size threaded Rod to use and spacing. °Best Epoxy Resin to hold threaded rods into masonry. °Depth of rods into masonry. Many thanks in advance
