How to Cure Concrete With Water and Plastic Membranes

The concrete curing process involves a reaction between Portland cement and water helping on releasing heat from the concrete at a desired and controlled rate. Without curing, moisture is lost too quickly and there isn't enough water necessary for the crystals to grow, resulting in weaker concrete.
