TETRA Road grade calcium chloride is used mainly for maintenance of gravel and dirt roads and in de-icing applications on paved and unpaved surfaces.
Calcium chloride is both hygroscopic and deliquescent. These related properties both involve absorption of atmospheric moisture and retention of moisture present in the soil, making it ideal for dust binding on gravel and dirt roads. An unpaved surface treated with this product, when cured and compacted, forms a hard and smooth riding surface, significantly reducing dust displacement.
Calcium chloride is a very effective de-icing agent. Calcium chloride is effective to temperatures as low
as -25°C. The use of calcium chloride to melt snow and ice and to prevent low friction conditions is an efficient tool in any winter road maintenance program.
