The hidden biology of your sidewalk's toughest surface
In short: Concrete is often viewed as an inert, solid material, yet it frequently hosts thriving mold colonies. This video explains the specific environmental conditions and microscopic structures that turn a construction staple into a breeding ground for fungi.
While concrete appears solid, it contains tiny pores that can trap moisture from the surrounding environment. Mold thrives in these damp spaces, particularly when organic materials like dirt or food particles settle on the surface. The video explores why certain surfaces are more susceptible to growth than others based on how they manage water and debris.
