Under the Essex County Council Salt Bag Partnership, Little Clacton Parish Council has salt available for locations considered important by the local community. Residents should contact their local councillor in the first instance.
How does salt work?
Water freezes when it reaches 0C. Salt mixed with water or moisture lowers this freezing point. The colder the temperature and the more water present, the more salt is required to lower the freezing point. The effectiveness of salt begins to lessen at about -3/4C, and by -6C the quantity of salt required to remove snow or ice becomes ineffective. A small handful of salt (approximately 20g) can treat approximately 1m/3ft squared of cleared surface. If snow and ice have already formed on the roads and pavements, then adding salt will not help because there is no direct moisture for the salt to dissolve into. Snow and ice must be manually removed first.
What about pre-salting in preparation for snow?
Pre-salting areas before snow falls will not stop the snow from settling, but it will create a layer of moisture that will freeze at a lower temperature than the snow settling above it. This layer will reduce the risk of the snow bonding with the pavement, making it easier to remove.
What about compacted ice?
If snow has compacted and bonded to the pavement and cannot be removed by hand, do not use salt on top of it. Instead spread cat litter, cinders or coarse graded/sharp sand (not building sand) or something similar over the area. This will become embedded in the ice and will make it safer to walk on.
