If you own a property in Tampa, chances are you could be dealing with crawl space humidity or efflorescence, a white, powdery substance that forms on concrete due to high moisture levels. Oftentimes efflorescence can form on concrete walls or foundation slabs due to wet soil. High moisture levels in your crawl space or the soil beneath your foundation can cause structural damage if left untreated. While mold is common in wet crawl space areas and can create poor indoor air quality, if you're seeing a white substance on your concrete slab foundation in Tampa, it may be efflorescence rather than mold growth.
Efflorescence looks very similar to salt or other crystal-like formations. It occurs when moisture moves through cement and forces salt to the surface. The salt hardens, leaving a bumpy texture.
How can you tell whether you're seeing mold growth or efflorescence in your Tampa crawl space? The good news is that efflorescence is not harmful to your health. The best way to determine the difference is to spray some water on the growth. If it disappears, it's efflorescence, because mold thrives in excessive moisture.
A few factors can cause efflorescence on concrete surfaces, such as on a slab foundation or on concrete blocks. Wet soil and water vapor can contribute to the formation of efflorescence. Installing a waterproofing system to your home in Tampa, like a foundation moisture barrier system from LRE Foundation Repair, can help prevent efflorescence.
While the appearance of efflorescence may seem concerning, it isn't hazardous to your health. However, it can be a sign of potential problems with your foundation. Efflorescence is often a sign of excessive soil moisture, which can cause hydrostatic pressure and damage your foundation, so you should call a Tampa foundation moisture barrier system professional as soon as possible if you're concerned about the presence of efflorescence on your property. Additionally, excessive water in your crawl space area can lead to mold growth, wood rot, and further damage to your foundation.
