When snow melts, or water pools on the road and then freezes during winter, it expands, causing the pavement to weaken and crack. Temps rise, ice under the surface of the road melts and leaves a gap. The road surface breaks down under constant traffic, creating a pothole. Potholes are one of the biggest problems for commercial parking lots and commercial paved spaces and it is important to handle them promptly before they create a danger to vehicles and drivers.
