I tiled a 250 m2 steel and concrete balcony floor in a seafront pub some 12 years ago now the owner has started to extend a third of the balcony out by about 4 metre's with the intention of putting up a conservatory which will give a floor area of about 100 m2 .He has decided that he wants geometric my concern is where the old and new balcony is joined in my opinion it is bound to crack,and with using geometric how would this look if there was a expansion joint in the pattern,I dont think a uncoupling mat would prevent this and the only other alternative would be to have a movement joint profile but what I decide on I think it might look odd with the pattern,any suggestion's would be much appreciated.
I will be using the matting anyway in general.
