For most floors condensation is the main reason for the sweating especially in warm weather.
Why does my concrete floor sweat in humidity.
Concrete science is still evolving.
If you have concrete in your home that routinely appears to be wet or feels damp then you may have sweating slab syndrome.
Concrete sweating usually occurs when warm air comes into contact with a cooler concrete slab and it causes the concrete floor to sweat.
Why does my concrete floor 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.
When warm humid air from outside comes into contact with the cold concrete the air rapidly cools and condenses on the surface causing the wetness.

Causes of surface dampness on concrete slabs and garage floors.
Why tile floors sweat.
After a humid night water vapor in the air will come into contact with the cooler concrete floor and will condense into morning dew.
Moisture as you would guess is the underlying cause of sweating on concrete floor slabs.
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.
Why floors sweat for most floors condensation is the main reason for the sweating especially in warm weather.
This usually happens when concrete slabs and the other materials that sweat reach dew point temperature.
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.
Humidity warm and humid air condenses into surface moisture when it comes into contact with the cool surface of your concrete floor or slab.
Sweating makes concrete slippery and dangerous.
The concrete mix itself in the event the slab is insufficiently cured or is otherwise holding moisture.
