Do I need a timber on top of my drawf wall or can the joists sit directly on the wall on top of DPC?

Anonymous user 15/03/2024 - 2.40 PM

Hi all, I am installing new floor joists on my ground floor. I was hoping to remove the 2x4 timber laid on top of my drawf walls to give me 2 inches extra space. Is the original timber laid on the drawf wall required, or can I lay DPC and the joists directly on top? Thanks!

Are you a tradesperson and able to answer this question?

Hello Theoooo, the wall plate is used during construction to level the floor and fix the floor joists to it, It should also have a damp proof membrane underneath it. On an old property that may have been a layer of tar. You will have no way of fixing the joists to stop them moving, prior to re boarding the floor. You must always use a damp course in any event. I would replace like for like, or use a 1 x 4 wall plate gaining one inch. Just a thought, but if you l lower the floor you will need bigger skirting boards or to adjust the plaster work.
