Seeling Basement

Hi, What do you use to seel the basement of your house? Like if some moisture and dampness come in the walls/floor? Not flood or water, but just damp. What can be done to dry it out?
Possibly a dehumidifier... but I also believe there is stuff you can slap on the walls that seels the water out.. anyone know more info about this stuff?

First, check that the surrounding grade has some pitch away from the house. Downspouts should extend at least a few feet away, and not pool. See if that helps. If not, your next job would be to dig around the foundation and coat the exterior walls with some type of tar or impermeable membrane. Then gravel backfill to promote drainage,and slope the final grade away from the house. Tom Work at your leisure!

Nothing you slap on the walls on the inside is going to work.
Step one is to determine if the moisture is coming in through the walls or is condensing on the walls. Tape some aluminum foil to the wall (like a foot square) come back in the morning and see if it is moist on side you can see. Take it off and see if it is moist on the side you can't see.
If the side towards the room was moist, you need a dehumidifier. If the side towards the wall was moist, you need to get the water away from the OUTSIDE of the wall.
Getting water away from the foundation is the first step to getting it away from the wall. The ground and walks should all slope away from your home for at least 10 to 20 feet. No downspouts etc. should empty in that area. If you got that done and it still leaks, then it means digging adding drainage and waterproofing the OUTSIDE of the wall.
Working from the inside to prevent water from coming in is like herding cats.

Go to HomeDepot, Lowes, hardware store and by some Drylock Masonary Waterproofing paint. http://www.ugl.com/DRYLOKframes02.html It works very well.
Good luck!
