So I'm still trying to get to the bottom of why we have to tip-toe across our master bedroom otherwise the floor flexes causing all manner of things to move.
Anyone able to tell me what the MiTek software used in designing PosiJoists 'Vibration Checks' section is trying to explain please?
Yes, nearest the camera is joists that make up the floor that bounces most annoyingly - you can just see the chimney.
I'm going to try measuring the flatness of the floor using a rotating laser level as a reference - though with carpet and underlay down it is going to be tricky to note less than a mm but now that I can see the difference just across the bathroom door gap I think there will be something I can measure
