Big Moose Pressure Cleaning is here to talk about why sidewalks become discolored and black, as well as how to fix it.
Black Film on Sidewalk Makes Them Slippery
There is no denying that Georgia is a humid climate. When a humid climate and porous concrete come together, it can be a recipe for moisture collection and spores can start to grow. The blackness on the top of sidewalks is usually algae, mold and bacteria growth. This can leave the sidewalk looking grimy and dirty. However, in all actuality, it can leave the sidewalk slippery and a hazard to those walking on it. While algae, mold and bacteria are the common issues that discolor sidewalks, this can also be caused by vehicle oil and airborne pollution as well.
