Sweating makes concrete slippery and dangerous.
Why does my concrete floor sweat in humidity.
Causes of surface dampness on concrete slabs and garage floors.
While the industry doesn t have all the answers it can be said that moisture issues in concrete floors tend to arise from one of two sources.
Why does my concrete floor sweat.
This usually happens when concrete slabs and the other materials that sweat reach dew point temperature.
Continue reading to learn how to stop concrete sweating.
This is not actually a problem with the construction however but an issue that can often be controlled or eliminated by changing the upkeep of the area and in some cases the controlled climate conditions.
Usually warm moist air and relative humidity enter the structure through the several openings windows doorways and vents.
Concrete sweating usually occurs when warm air comes into contact with a cooler concrete slab and it causes the concrete floor to sweat.
Faulty missing vapor barrier moisture from the ground can seep up and surface through the concrete if no vapor barrier has been installed or is faulty.
The concrete mix itself in the event the slab is insufficiently cured or is otherwise holding moisture.
After a humid night water vapor in the air will come into contact with the cooler concrete floor and will condense into morning dew.
Why floors sweat for most floors condensation is the main reason for the sweating especially in warm weather.
Why tile floors sweat.
If you have concrete in your home that routinely appears to be wet or feels damp then you may have sweating slab syndrome.
Moisture as you would guess is the underlying cause of sweating on concrete floor slabs.
When the air with water vapors enters your house through windows doors or vents and comes in contact with the cold tile floors the air rapidly cools and condenses on the surface causing the wetness if nothing is done about the condensation the concrete slab becomes darker.
Humidity warm and humid air condenses into surface moisture when it comes into contact with the cool surface of your concrete floor or slab.
As the concrete surface is at dew point the moisture of the air tends to condense on the concrete surface where it is not readily absorbed and form water droplets on the surface thus leading to concrete sweating.
