It all depends on your situation. If your problem is due to the water table, they will probably work if installed correctly. However, I would do more investigation. Is your basement floor cracking? If you truly have a water table problem, it probably would be.
My advice is to do as much work outside as you can. Get all water away from your house. Do some light reading:
