Water stay at some random places on terrace , is it have to to do with marble ragrai ?? Did poor ragrai is cause or bad sloping is cause or the marble ragrai wala did not do his job well ?? Solution
Its not the marble ragrai walla. Its the marble fixer who did not check the water level. The regarai guy can only fix hardly 10% of the prob. Any more can damage the marble,
Solution is to take off the marble and fix again with proper sloping
