❶ Drainage Systems
One of the most common solutions to a flooding parking lot is adding a drainage system. Also known as “underdrains”, these must be installed below your pavement’s subgrade, which means it will require a certain degree of demolition and repaving. Drainage systems direct water runoff below the subgrade and into a lower gradient. This diverts water from paved surfaces and back into the natural water table. It is also helpful to have asphalt poured thicker in areas where heavy rain fall is common. This will provide more permeation room, allowing water to drain fully.
❷ Sloped Asphalt
Another common method for preventing flooding and subsequent water damages is to pour asphalt pavement in an angled position. This diverts water runoff away from pavement, thus preventing flooding. If your parking lot is flooding on a regular basis, it may be time to have it repaved using this method of asphalt pouring. It is a proven effective method that it compatible with various types of parking lots and paved surfaces. Again, talk to your Indianapolis asphalt paving company for specific recommendations for your particular paved lot. They will provide accurate and current information that will help you choose an effective diversion against flooding.
