Topic: leakage in new slab

I am constructing new house. After completion of slab , next day it is observed that water is leaking in 2-3 locations. After 8 days 1 leakage is stopped but 2 locations still have leakage. It  seems that this may be due to not doing proper compaction.
Pl. provide suitable suggestion

Dear Milind
        This problem is either due to defect in compaction or putting  the mix which is lifted from side not having proper ratio but have more bazri and less sand and cement contents.
For remedy clean the affected area, make the area rough and  put cement water mix and finish the top with cement and coarse sand mortar. properly and cure properly.
The second option after making top surface rough pure cement coarse sand and 6mm to 10 mm bazri mix in the ratio 1;1.5;3 on the affected area overlapping the area at least 6'' on all side and thickness of mix should be 2'' thick and thickness  will be cover by floor or tile terracing cure the area.

It clearly suggests that slab was not properly constructed. This points are the defects but are very common as well due to issues with the material ratio, shuttering, labour etc. That can be fix by having a layer of cement mix with water done on the entire lantel before tiles. The more fix would be done by having proper plaster below it later.
