Civil Engineering/Tiling


Dear Sir

In some instances tiled floors get pop up withperiod of time. Can you explain the reason/s

Dear Priyantha

I would be due to lack of proper sub base or lack of due care about water saturation of tiles when installing them. To prevent this situation you would pour light mortar ( in totally liquid state on the finished level and after that wood powder on it to remove and clean. In some cases the presence of quick lime (CAO) in the mortar may cause tile uplifting because of humidity absorbsion.
