How Mold Can Infest Your Foundation And Concrete Areas

Have you noticed grey or black patches in your concrete floors or walls? Your home could potentially be facing mold invasion.

The formation of mold can occur on virtually any surface in damp conditions. For instance, dirty concrete areas can become a breeding ground for the fungi.

Home foundations are typically porous, so they’ll absorb water from the exterior, allowing it to enter your home’s interior. If you wish to know how mold can invade your foundation and concrete areas, check this out.

Mold on Your Foundation

Your foundation is your home’s lowest point besides being adjacent to soil, which has considerable moisture. If minor cracks exist in this part of your home, the soil moisture may even penetrate into the smallest opening, resulting in mold development.

Water drainage also affects the foundation, so if you own a suitably graded yard with appropriate rain gutters and drainage, this may be a minor problem.

However, numerous homes lack proper drainage equipment or yard grading. Furthermore, sprinkler or rainwater frequently penetrates into the space between the surrounding soil and the foundation, contributing further to the mold issue.

Another possible cause of foundation mold is the fact that this part lies under the ground with negligible air circulation. You’ll therefore discover that some water in your attic can dry easily because of circulation and subsequent evaporation.

However, water in your basement or foundation doesn’t evaporate as easily, leading to mold growth. Foundation leaks permits water to damage your home’s structural integrity, potentially causing mold.

The fungi can grow within your flooring, carpet, walls, and personal property once water leaks into the basement, home, and foundation.

Bear in mind that the infiltration of mold in your home, your family’s health is at risk. Mold exposure can affect your family’s capacity to inhale clean air while causing allergic reactions.

Water accumulation in the yard and around your home’s base could cause frequent water issues for your home’s foundation.

If the ground around your house slopes towards your home, rainwater will consequently accumulate at the foundation. If this generates constant issues, you might need to perform landscaping to alter the ground’s slope for water to drain away from your home.

Concrete Mold

Concrete isn’t an organic material, so the material itself doesn’t serve as a food source for mold. ¬†However, concrete surfaces and walls can trap organic materials, for instance dirt and dust, which offer a food source for the fungi.

This material is also porous, so it can be excellent breeding ground. The problem with this material is that it absorbs moisture very slowly. For this reason, water damage can exist for a considerable period before it becomes obvious.

The key to mold prevention is checking concrete surfaces routinely, especially in areas with high moisture such as the crawlspace and basement.

Sources of Concrete Mold

Humidity

Air always contains some moisture or humidity. Humid air typically sinks and finds its way to your basement.

When humid air contacts a cool basement wall, it condenses into liquid water. In this case, condensation, air, and food promote mold development.

You could build airtight walls to prevent humid air from reaching the walls, insulate the home’s exterior to prevent condensation, or install a dehumidifier to maintain low humidity levels.

Liquid Moisture

While concrete might not appear like it, it’s fundamentally a huge sponge. It comprises water and it is porous enough to allow water in and out via capillary action.

The key to maintaining relatively dry concrete walls is keeping water off the walls. You can achieve this by:

  • Repairing any foundation cracks
  • Installing a French drain or sump pump to eliminate water from the basement’s interior
  • Maintaining the cleanliness of your downspouts

Are you suspecting mold infestation in your foundation and concrete areas? Ensure you adopt the necessary measures to eliminate the problem to avoid further damage.
