Maybe you need to address the cause of the wetness. Here is my list on the best means to address this: Make sure your downspouts have a pipe that collects the water and sends it as far away from your foundation as possible (downhill). If you don't have gutters I would put them on to collect the water. Pull away the dirt around your foundation walls (the lower you can go the better) Be careful here as you don't want to cause the foundation to shift if you have stone or rubble walls. If you can get to the top of the footing thats ideal. Then get water emulsified tar (only sold during the warm months) with a brush and/or roller paint the foundation walls on the outside with a good coating. Once it has dried go over it again this time while its wet put 2x4 foot Styrofoam sheets against it (gluing the sheets to the wall) make sure to butt up the seams tightly and make sure you don't go above the soil line as you don't want the tar or the Styrofoam visible. If you can't get to the outside walls you can try sealing the inside walls with hydraulic paint to prevent the moisture in the concrete to enter the living space. The last issue is the floor. Here you will need to see if the drainage is adequate. Locate the lowest point the house sits this is the ideal placement for a sump pump as you want the water to collect at the point you can discharge it away from the foundation. If you do get a lot of water you may need to look at using injecting grout along the hill side wall to reduce the water going under (moving it away). If you can't do that you may also find using a hydraulic floor paint can help. Lastly, try to create as much ventilation as you can. The only problem with this is in the winter time and humid days this won't help. We're back into needing a dehumidifier. But maybe with the other stuff fixed you won't need it as much so it will last longer.
