Reasons For The Moisture On The Concrete Floor

Concrete is actually a very porous material. At its heart, it's made of rocks and water. When the water dries, you're left with tiny holes all throughout the material. Therefore if you don't have some kind of sealant or other protective solution, you will always have moisture in concrete slabs.

After all, what causes concrete to sweat could be a variety of things: humidity outside, liquids used on or around the concrete floor, or foundation leak.


Especially in Georgia, the humidity makes surfaces sweat. Concrete's no different and is not immune without proper coating.


It's common to use concrete floors as workshops, public works areas, and other project spaces.

Naturally, liquids are going to spill here and there. The more corrosive or chemically loaded the liquid is, such as gas or cleaning solutions, the more likely it is to damage the concrete. Therefore, you're more likely to notice sweating.

Foundation Leaks

Your concrete itself might be cracked, but a deeper concern could be the fact that moisture is seeping up from beneath the concrete layer. This could be due to a foundation crack or leak.

How To Get Rid Of Moisture In Concrete

If you've got moisture coming up through your concrete floor, don't worry, there are solutions. Depending on where the floor is located and what it's being used for, you can apply different coatings.

For instance, unfinished basements do very well with epoxy coatings. They protect the floor from abrasion, wear and tear, and also moisture. Garage floors should be treated with polyaspartic coating.

This is stronger and more durable than epoxy coating. It stands up better to external elements like UV rays and humidity to prevent corrosion. It also resists tire markings and heavy vehicle abrasion.

Therefore, by applying the right sealant to your concrete flooring, it will last longer, look better, and stop moisture from coming through the floor.
