Concrete Sweating

Concrete sweating is the phenomena of gathering of water droplets on the surface of concrete due to the difference in temperature of the outer environment and concrete.  Causes of concrete sweating 1. Dew Point The concrete needs to be below the dew point temperature for concrete sweating to occur because Dew point in the atmosphere is the most common cause of concrete sweating. Concrete sweating can happen when warm and humid air hits cold concrete inside a building. The moisture in the air cools and condenses on the surface of the cold concrete, thus makes it wet and slippery. 2. Wet adjacent soil Concrete sweating can occur in retaining walls and basements where the soil on the other side of the wall is wet. Although concrete is a solid material, water and moisture can seep through it. Water from the soil can slowly creep through the concrete wall and appear as concrete sweating on the other side. 3. Salt deposits Salt deposits in concrete can attract
