What grime does to brick pavers and concrete
In South Florida a paver walkway is wet, then baked, then wet again, most days of the rainy season. That cycle feeds mildew and algae into the pores of brick and concrete, and foot traffic grinds the dirt in. What starts as a faint shadow turns into a dark film that makes a clean entrance look neglected.
Washing is not only cosmetic. A slick green film on a sidewalk is a slip hazard when it rains, and grime left to settle hides cracks and loose joints. WGG has washed brick pavers at a commercial plaza and cleaned the lane at a bank drive-thru, and every job starts with looking at what the surface is actually carrying.
