De-icing salt

Winter road servicing

Making sure that the road network is well serviced in the winter saves many lives each year and helps economic activities to keep running.

The use of de-icing salt is the best method for this.  It is cost effective, efficient as well as being environmentally-friendly.  To reduce the environmental effects even more, the Salins Group encourage “smart salting”.

The effects of sodium chloride on the environment are limited if it is used in the correct conditions :

  • the salt is stored in hangars, and when this is not possible, it is covered with a tarpaulin.
  • when it comes to the actual salting, this should be done wisely: just the right amount of salt should be used.  In this case, the salt is greatly diluted (10 to 30 g/m² of road) and its concentration mixes rapidly with natural levels.
  • The best way to reduce the impact of salt on the environment is to optimize its use, especially when it comes to training the people in charge of the actual salting.

The technique known as “salt brine” is a mixture of rock salt and brine which is simultaneously spread onto the road which increases the effectiveness of the product while reducing the amount of salt used.  This practice was started in the 1970s by the Compagnie des Salins du Midi et des Salines de l’Est and is steadily becoming standard practice throughout the country.  The progress made in the spreading equipment, enabling regular low doses to be spread, also contributes to minimizing the amount of salt used.
