Wet basement floor.

I would tend to agree with most everythign Tomh said, he is a regular and I can't remember disagreeing with him much at all.

Here is what I would do with that basement...

Start the project in the winter after the rains are done and finish it before the thaw in spring.

Cut the concrete all the way around the perimeter of the entire basement and remove it, I'd probably go for about 12".

Cut a trench/trunkline to a location where you can install a sump pump, cut out the area where you will put a sump bucket, probably make it about 30" square.

Remove the dirt and install a cloth wrapped 4" perforated flexible drain with a minimum 1/8 pitch all the way around the perimeter and through the cut to the sump bucket.

Apply gravel pea rock over the drain and apply plastic over the drain.

Fill in any remaining areas with the dirt in the basement and apply a minimum of 3" of concrete. Given your problems, I am undecided about whether to use beavertail corrugated drains because you might have more trouble with water bubbling up than condensation not running down. Do some more research on that one...

Drain the sump bucket to daylight, not the house to a point where the water can't return to the dwelling or a neighbors house.

You will no longer have a seriously wet basement.

After this, I would be inclined to raise the floor using green treated 2x4s and green 1/2 plywood. I might be inclined to do this in order to eliminate wet or moldy carpets.

This must be done with consideration for venting..

Good luck, gotta run.
