This is the answer to the question How to avoid condensation under the floor?
Revision 1
Moisture appears from temperature differences.
If the temperature of the basement and the living space are not much different, there will be no condensation. The source of moisture in the basement may be upward flows from the ground beneath the house or moist air driven from the street by your ventilation system. Or both. In order to calculate the cause.
1. Seal your vents. Make the air communication between the basement and the room above-align the temperature (sometimes simply opening the lid (hatch) or organize the air vents through the adjacency of the floor to the wall. You can equalize the temperature by heating the air in the basement with an electric heater.
2. If after the alignment of temperatures the moisture remains-the source of upward flow from the ground. Cut them off by waterproofing the soil (floor cellar) and waterproofing of the foundation.
A common mistake is to first let the moisture into the basement and then heroically air it out through the holes in the basement, while launching new portions of moisture.
