Costco has a unique need; they are super busy most days and are limited when they can close their parking lot to seal it. On Labor Day, one of the few days during the year when the store is closed, our team swooped in to take care of business. Within one day, our team cleaned and sealed almost 400,000 sqft of the parking lot. Our striping crew followed behind, putting down the lines to ensure we completed the project in one day.
