Expansion joints in screed

fclauson

Any advice on how often and where to put expansion joints in the screed which has UFH in it - we will be tilling over the top.

I have read it should be max 40Sqm per segment and the at least every liner metres 8M but the sqrt of 40 is 6.3M so does that mean 6.3M squares are the max ?

I got these cut into my floor (with a grinder and masonary blade) by the flooring conctractor a week or so after the floor was poured.

He cut them where the concrete polishing contractor told him.

In the case of a house, as opposed to industrial uints, where the floor area is relatively broken up by internal walls, the prevention of cracking tends to happen where walls and floors meet rather than a sq meterage/linear meterage rate.

Any good flooring contractor with experience will be able to identified spots prome to cracking for you

I was always told every 5-6m in both directions for expansion joints
