Salt Brine is an excellent option for Ice prevention.
Slick sidewalks and roads are hazardous! Removing compacted snow and ice with shovels or snow blowers is not always an easy task. Salt can help by “undercutting,” or loosening the snow or ice. Contrary to popular opinion, salts primary function is not to completely melt snow and ice but can facilitate snow and ice removal by lowering the freezing point of water.
Salt melts down through the ice or snow to the hard surface, then spreads out underneath. This undercuts and loosens the snow making shoveling and plowing more efficient. Products are available as either solids or liquids, but the majority of commonly used products are applied as a solid.
Before a solid deicing chemical can do any melting, it must absorb moisture and create a brine solution. The concentration at which chemicals melt ice and create brine depends on the ratio of the chemical to the amount of water in the brine. More isn’t always better when it comes to chemical concentration. If you increase the concentration of the product beyond what is recommended, the brine solution’s effectiveness decreases substantially. “Snow Patrol” quality control, assures the optimum solution for our local conditions.
Brine is a recent choice for businesses to implement Transportation departments located in the season’s icy grip are implementing new strategies to keep roadways safe. Governments have been quick to adopt “Brine” deicing systems. Private business has been fast on its tail.
Salt has always been applied to roadways since it lowers the freezing point of any water it comes into contact with. Traditionally, this was accomplished by applying solid rock salt before and after snowfall to reduce ice and snow. However, this strategy is only effective when temperatures are above -10 degrees Celsius. Most days in the Fraser Valley this is acceptable.
The limitations of dry “Rock Salt” has led transportation departments to implement new strategies to combat winter weather. In recent years, there has been a growing transition from reactive strategies to more proactive strategies.
Using salt brines, which is any liquid salt mixture, before anticipated snowfall was discovered to be more effective than using solid rock salt. Brines have the same melting characteristics of solid rock salt, but since it is applied in liquid form, the salt can begin to work immediately. The brines are also more effective in lower temperatures.
The use of brines is known as anti-icing or pre-wetting measures. Anti-icing can be accomplished by using traditional salt brine and applying to roadways in preparation for snow and ice. Using salt brines proves not only to be more effective on roads, but it is also cost effective.
Brine works exceptionally well if we expect to have prolonged periods of sunny and dry conditions. Brine will prove to be a cost savings measure for our customers. Rock salt tends to migrate due to traffic from its intended position. This tends to require more applications to keep ice under control. Since Brine is applied as a liquid, it will stay put for a longer period of time.
Being proactive to prevent Icing is also efficient and cost effective. It takes four times less salt to prevent ice accumulation than to remove ice after it has formed. Pre-wetting [using salt brines] has been shown to increase both the performance of solid chemicals and abrasives, as well as their longevity on the roadway surface, thereby reducing the amount of materials required. Combined with accurate weather forecasts, anti-icing is a more proactive technique for winter transportation and pedestrian safety.
