Concrete parking lots, walkways, and entryways catch everything. Over time, dirt, road grime from your tires, mold, mildew, oil, grease and other materials from automotive traffic and foot traffic cause the concrete to become gunky, slippery and just dirty. Our professional grade high-pressure concrete surface cleaners generate high pressure to wash all these contaminants. We use specialized equipment designed to agitate and deeply clean concrete. This special machine reaches down through the porous concrete to draw out material that causes concrete to become stained and dirty.
