Calcium Chloride keeps water-filled Plastic Jersey Barriers from freezing in wintry conditions
For Plastic Jersey Barriers that are used in cold-weather conditions, calcium chloride has been employed to prevent the water inside from freezing. Calcium chloride is the chemical compound resulting from the combination of calcium and chloride, usually comprised of dissolving marble or limestone chips in hydrochloric acid.
When kept at room temperature, calcium chloride remains in a solid-state. However, even at very low temperatures calcium chloride will readily dissolve in both water and ethanol. Because of this characteristic, it is very effective in lowering the freezing or melting point of water.
Calcium Chloride is the fastest ice melting chemical compound which is why it is used on roads and highways in winter conditions to reduce the risk of ice forming. In chemical terms, calcium chloride is relatively cheap, costing about fifty cents to a dollar per pound.
Each Jersey Barrier requires roughly 12 pounds or 1 ½ gallons of calcium chloride added to the water.
Please note calcium chloride is the acceptable solution by the EPA and in all states. Sodium Glycol is no longer accepted by the EPA and therefore is not offered.
