Should I be worried about tiling over a hairline crack. The screed is 65mm thick and was layed early April. The crack is about 3' long but hasnt moved in the last couple of months. Its so small it can only be seen if covered in water. I'm asumming the UFH pipes are OK but dont know how deep the crack is or if the expansion/contraction of screed will crack the tiles.
