Some of our frequently asked questions.
No. Salt will not have much of an effect on snow until traffic mixes the salt into the snow which will form a much less hazardous slush. If snow is predicted, we will spread in advance so when the first snow falls it can start to mix with salt to create a saline solution which can reduce the build-up (accumulation) of snow and prevent the formation of ice at road surface.
However in prolonged periods of snowfall, we may need to plough the snow constantly to slow the build up of snow which can cause huge problems if left too long. Accumulated snow will have to be ploughed away from the roads or cleared in the pedestrian areas, but this is made much easier by salt spread in advance of the snowfall as the salt that has already been applied reduces the risk of snow freezing on the road surface.
Treatment of road surfaces with salt is carried out to prevent frost and ice forming and reduce the build-up of snow to help provide safe access around the site. Our clients have a legal obligation to control slips, trips and falls. Our services ensure you have acted upon the H&S guidelines to help prevent such occurrences.
Frost and ice form when water/moisture in the air freezes. When salt is applied to the road, it attracts moisture from the ground and air and creates a saline solution. Saline solutions freeze at a lower temperature than water (usually around -6 degrees), so frost and ice doesn’t form on the surface, even though the temperature is below freezing.
The best time to grit is during the night. Gritting at this time ensures the best performance of the grit, it means we can apply salt to more areas of the site due to vehicles not being present. It also reduces the risk of any incidents on site that may involve the public and cars being struck with the grit salt.
Spreading salt at these times also means the roads are treated in advance of workforce arrival. In most cases we will need to visit your premises prior to a volume of cars & people being on site, so that we can get the best possible application down.
We aim to have a reaction time of 2hrs from your request to us being on site. However, this is not always achievable due to main road traffic, especially in rush hour and if the highways are congested due to dangerous conditions.
