Water entry and capillary action – GreenBuildingAdvisor

Any advice would be appreciated . Had a wireless internet line installed and buried next to my foundation , well it was placed on the ground because its  path was not  completly covered with dirt  . We had some rain and water made its way under my foundation  . I know because my tile floor started bulging with the rain  . Slab foundation climate 2 . What can I do to stop water making its way under my foundation? I can pack dirt tightly or should I add cement to the dirt like a slurry mix ?  

I did pack dirt and I got capillary action.
