WHY WE SALT ROADS

Living in Canada, where temperatures are often below 0°c you have most likely seen large commercial trucks spreading rock salt on the ground. Applying rock salt or deicers to our roads and streets is the most effective way of ensuring that ice does not form and the roads are safe to drive on.  Did you know, road surface condition is the single most important safety factor during a winter event; more important than visibility, precipitation intensity, air temperature, wind speed or exposure. Applying rock salt ensures that everybody can safely get to their destination. It not only is used on roads, but our walkways, parking lots and side streets. Did you know applying rock salt to ice does not actually cause the ice to melt? When rock salt is applied to the ground, it lowers the freezing temperature of the moisture which means that now for ice to form on the road, the temperature would have to become much colder

HOW ICE MELTERS WORK

When rock salt is applied to ice and snow, it creates a brine that has a lower freezing temperature than the surrounding ice or snow. Rock salt is relatively easy to store and handle, easy to spread, relatively harmless to skin and clothing and believed to be harmless to the environment when used and stored properly. The use of rock salt for winter maintenance is founded on the theory that dissolving one substance in another alters the freezing point of the second. Rock salt lowers the freezing point of water. The greater the concentration of rock salt, the lower the freezing point, although there is a limit of temperature below which salt will not melt ice. This is called the eutectic point (-21° C). The effectiveness of salt however can vary due to a number of factors, but on average melting begins on contact when salt is spread on ice or snow. This produces water, dissolving more salt and producing further melting. The rate of melting will depend on the surrounding air and ground temperatures. Other influences on melting rate are the particle size of the salt and the amount of mixing often caused by traffic.

DIFFERENT TYPES OF SALT STORAGE DOMES

Storing your salt on your own property saves you time and money. But, it is imperative to pay special attention to your storage facility to protect your investment. Salt needs to be kept dry and contained. Depending on how much salt you use in a year, we’ve compiled several salt storage options that can work best for you.

THE LARGEST SALT MINE IN THE WORLD, GODERICH ONTARIO

The world’s largest salt mine is right here, in Goderich, Ontario. You can find the salt mine located beneath Lake Huron. It’s so extravagantly large that it’s hard to visualize: the mine is as deep as the height of the CN Tower. Yet, all of this salt was discovered by accident...

SALT STORAGE DOMES: A BUSINESS SOLUTION FOR YOUR SALT

Road salt becomes a very profitable business when the winter months hit us. Motorists need it for traveling, companies need it so their customers can get to them, and snow removal contractors rely on it to help their clients keep roads and lots clear. Buying road salt in bulk saves time and money, so it needs to be protected and that’s where salt storage domes come in.
