HI All We have largeish (12") floor tiles in the sunroom. There was always one by the outside door that 'clicked' when you stood on it (didn't more enough to actually see - but just to hear)
After three or four days & nights of 40mph winds (may not be relevant) I heard a noise like somebody knocking over a load of broom-handles - and now a large area (maybe 6ft square) of the tiles appear to be 'live'.
Again - not enough movement to see - but when you stand on them there's a sound like thin ice creaking....
I think I probably know the answer - but is there any alternative to lifting them up and re-laying ?
Thanks Adrian
