Web1) Maintaining mixing water in concrete during the early hardening process. Ponding and immersion Ponding is typically used to cure flat surfaces on smaller jobs. Care should be taken to maintain curing water temperature at not more than 20 degrees Fahrenheit cooler than the concrete to prevent cracking due to thermal stresses.
