You may be able to seal the driveway, but i would look into where the moisture is coming from and can it be eliminated. If you decide to seal, be sure it is correctly cleaned prior to sealing, and if you are doing it yourself, I would use the water based sealer, WITH shark grip added so you do not end up with a very slippery surface when wet.
