Causes for bathroom leakage
	
	
		Hi,
I have newly done up my bathroom. Yesterday I got a call from my apartment maintenance guy that my bathroom is leaking. On examination I found water mark on the outer wall of the bathroom close to the floor level. Also this side of the wall on which leakage is appearing, there are no concealed water pipes, taps etc.
Could the leak be because the gaps between the tiles are not properly filled with with cement? Could there be nay other cause?
Thanks for your time.
Regards,
Aparna
