A hardstand is a paved area for parking heavy vehicles.
Heavy vehicles can sometimes be parked on areas of unpaved compacted earth for short periods of time. But if left parked in these areas for extended periods of time, heavy vehicles can sink into the soil and become mired.
Hardstands are paved with materials including concrete heavy duty pavers which give a lot of maintenance flexibility over other products as well as strength for the life of the project or asphalt/macadam. The paving is usually designed to be thicker and more durable than drives, city streets, or automobile parking lots in order to support the weight of heavy vehicles such as large airplanes, tanks, or heavy trucks.
