Sweaty Basement Floor & Laminate

My concrete basement floor sweats during periods of high humidity. I use a dehumidifer, but it only helps a little. A contractor advised laying DriCore over the entire basement, then applying the finished flooring. This seems like an extra expense. Can't I just lay the padding and a laminate product? This seems like it would avoid the humid air from coming into contact with the cold concrete. Does anyone have experience with this problem and/or solutions?

two problems. The condensation you are dealing with and the moisture that typically migrates up through the concrete. If the floor normally looks dry it is because that moisture is evaporating. Cover it with something to hold the moisture in and it will accumulate and who knows what will begin growing. Basements that were not built to be dry right from the start will always have to deal with the moisture that migrates through the concrete.

Start with a humidistat to get a reading on the moisture levels you are dealing with. Next would most likely be a bigger/better dehumidifier. Third is ti identify where that moisture is coming from. Humid weather conditions can carry a lot of moisture inside and air leakage into a basement is common. That can be reduced. Next is the foundation, walls and floor. Tape a 3'x3' piece of plastic over an exposed area of the concrete floor. Wait a day and remove it to see if there is moisture or a darker color indicating moisture.

Landscaping around the house to move water away before it can seep in can help.

Wood is not a good choice for wet basements and laminate is not even wood, it's a picture of wood on something closer to cardboard, it will definitely not hold up to moisture.

As Bud indicated, you need to do some more investigation of your moisture problem and then you can figure out the solution.
