Parking lots that are not maintained properly develop bigger problems such as loose gravel and dirt. The build-up of gravel and dirt creates a “sandpaper” effect when vehicles drive over the loose debris. Broken glass, wet papers, and loose leaves left to accumulate, further contribute to lessening the life of the asphalt as well as create safety issues and environmental hazards. PBC develops and implements proper maintenance programs that expands the life of the asphalt and removes any safety risks and hazards.
