Expansion joint needed or not?

[burncross]

Doing a shop floor over the weekend, Its a wooden floor measuring 8m x 5m (40sq/m), using 1000 x 500 and 500 x 500 porcelain, skirting to go on after tiling completed so a expansion joint can be incorporated around the edge, Is a expansion joint needed along the 8m part of the floor? or is every 10m?

What thickness is the ply?

Those 1000 x 500 are big babies, might be worth putting in an expansion joint if the pattern allows?

 

[david campbell]

there should be an expansion joint every 5m so ever

 

[Perry]

would suggest one number divide it into 4x5 mtrs ete
