[Picture 1] The room 11.48m long and 3.98m wide. My friend in WA said it is unnecessary to have this expansion joint inside house unless over 12m. And I went through the pictures I took when the builder took to another house with the same floor plan, and there was no expansion joint. [Picture 2, 3] Moreover, my friend also said if this joint was designed to be placed here, it is supposed to be on my floor plan which isn’t showing. [Picture 4] The supervisor told me that the room is to long and this joint is to prevent ceiling from cracking, but I wasn't sure why other houses don't have one. So I am here asking for help if anyone knows about this in Tassie. Appreciate your help!

I was looking for some guidelines so I can send over to the builder and ask them to redo the whole ceilings. Re: Ceiling expansion joint 3Aug 01, 2020 8:33 am 11.48m is pretty close to the 12m rule so maybe the builder was just being cautious. As for the direction the sheets were laid, are there battens nailed or screwed to the underside of the trusses before the plasterboard was installed? If there were then the plasterers have laid the sheets the correct way. Also by the time the builder has applied some caulking compound to the expansion joint and it is painted you will hardly notice it - as per most joints.

Stewie Thanks Stewie My builder took me look through my house last week as they were really busy. And I checked to make sure the steel battens are installed. But it is a bit weird that my builder said they never draw expansion joint on their floor plan, and they will leave the expansion joint as what it is, will not use anything to fill in. Regards, Tom To my understanding early saw cuts are to control shrinkage cracks, so doing them now would be pointless. Control joints may reduce ugly cracking during periods of soil… 3 9830 Hi all I need a guidance on how far I need to space expansion joints in the concrete driveway and its type (keyway/foam.)
