sealing basement walls

For those of you that have either finished or are in the process f finishing, what did you do about the concrete floor? Did you just put carpeting on top of the concreate? Did you put a subfloor in?

The basement of my house was waterproofed almost 30 years ago by a company that's no longer in business. The outside perimeter was dug up and two sump pumps were installed and a weeping pipe was laid that empties into the sump wells. My problem now is that the weeping pipes seem to be clogged and when there is heavy rain or spring thaw the small drainage holes that are in the side of the wells do not drain fast enough to keep the ground water levels low, resulting in water seeping in at floor level. Can anyone give me some tips on unplugging the weeping pipes? Thanks for any help!!!! :)
