Why Garage Floors Sweat Condensation occurs when moist air comes into contact with the cool concrete of the garage floor. Upon this meeting of two conflicting temperatures, the air begins to cool below the dew point, condensing on the concrete’s surface. The result is a misty looking garage floor.
How do I stop moisture in my concrete floor?
Methods Used to Stop Moisture in Concrete Floors Low-permeance Vapor Barrier or Retarder. A Low-permeance vapor Barrier or retarder can effectively keep below-slab moisture from reaching the flooring system. Allow Natural Drying of Concrete Slab. Ad. Keep Excavation Free of Water.
What causes damp garage floor?
When warm, humid air comes in contact with a cold concrete slab, water vapor in the air can condense on the surface of the concrete in the same way that a glass with ice sweats in summer. This can allow moisture from the ground to penetrate up through the concrete, resulting in damp conditions.

How do I stop my concrete garage floor from sweating?
How to stop concrete sweating Dry out the room by air movement: a high volume low speed fan works well. Turn down the air conditioning/turn up the heat to keep the concrete floor temperature and the air temperature at similiar levels. Use a dehumidifier to remove moisture from the air and reduce the condensation.
How do I stop my garage floor from sweating?
Stopping a Sweating Garage Floor Decreasing the humidity in the air. Increasing air circulation in the garage. Increasing the air temperature in the garage. Changing the garage floor surface. Keeping doors and windows sealed.
Why does my concrete garage floor get wet?

The issue could also be caused by poorly installed concrete (moisture below the slab). There is a simple test you can perform to find out which you are dealing with.
Why is my floor sweating?
SSS happens from moisture that accumulates from the difference between the inside air temperature and the floor temperature. When the air vapor cools down and matches the floor temperature, condensation forms on the concrete, this is also known as concrete sweating.
What happens when water sits on concrete?
Water containing bicarbonate ions and carbon dioxide causes a reaction known as carbonation in concrete. As the concrete becomes more acidic and damage progresses, the acids will eventually affect the protective layer of iron oxide on steel reinforcements, leading to corrosion. Steel expands as it corrodes.
What causes wet basement floors?
There are just three sources of moisture: Liquid water from rain or ground-water. Interior moisture sources such as humidifiers, unvented clothes dryers, bathrooms and cooking, as well as the moisture in concrete after construction. Exterior humid air that enters the basement and condenses on cooler surfaces.

How do I stop my concrete from puddling?
The best way to prevent patio drainage problems is to plan for them when the slab is installed. If your landscape prevents you from pitching the patio to allow for natural water runoff, your concrete contractor can install an in-slab drainage system with gravel-filled channels to carry the water away.
How many days should you water concrete?
Minimum curing time for cement concrete:- Concrete is kept moist for at least 28 days. Nowadays, due to lack of time, the curing can be achieved by following modern techniques in 14-20 Days. Nevertheless, it is always advisable to keep concrete moist for at least 14 days.
Why are my basement walls sweating?
The concrete in your basement walls and floor will absorb the heat from the exterior temperature in the summer, which makes it warmer that your conditioned air. When the air in your basement meets the concrete wall, the moisture in it will condense and your walls will sweat.
Are garage floors sloped?
Garage floors, unlike floors inside your home, are sloped to promote drainage. In most cases, the angle of the slope is gentle enough to be barely perceptible. The floor may appear flat until you try to install a level bench or floor-mounted cabinet.
