Sunken Den in my house with water table seepage.

Have searched youtube to no avail for suggestions on how to keep rain water from getting in my sunken in den in my house when we get more than 3 or 4 inches of rain in 3 or 4 days. I know it is a water table problem because it is not pooling up in the same spot every time and happens in different areas every time it gets in the house. It is never more than a half an inch of water that gets in and it never covers the entire den floor. The den is 2 steps down (about 8") from the other areas of the house and the den area is about 20 ft. by 20 ft. with porcelain tile and grout. We shop vac every time it happens and it has happened 7 times since the "GREAT" flood of 2016. I've been told that we probably need to pour concrete at least an inch thick and that will send the water elsewhere. I'm not gonna do anything until I know exactly what needs to be done so the problem is fixed. I don't mind throwing money at this problem as long as I know it is gonna work. I'm desperate O-T Lounge fellas. Any suggestions are appreciated and I know the first step is to call a specialist in this area but I'm not sure who to call? Thanks in advance.
