Winter Gritting

winter-gritting-1What we do

After a sub-zero temperature has been predicted we start spreading the salt, it is much better to treat the roads in advance of the temperature falling to freezing conditions i.e. before the roads become icy and dangerous.

How our gritting works

We begin gritting based on the weather forecast and conditions, which is monitored in advance in order to predict low temperatures in different areas, most importantly looking at surface temperatures, which can be a number of degrees lower than the actual air temperature.

How much salt do we use?

This can vary depending on the area, however according to guidelines the recommended quantity of salt for precautionary salting is approximately 10-15gms/m2 and 40gms/m2 when we are salting during ice and snow conditions.

How the salt works.

Salt can stop the ice from forming (hence the importance of precautionary icing) and melt the existing ice or snow by reducing the freezing point of moisture on the road surface. It is important to be aware that salt does not work immediately and needs to be trodden down by pedestrians or vehicles to start working – we use specialist machinery to speed up this process.

After gritting will our surfaces be 100% safe?

Unfortunately no road surface can be guaranteed as completely safe. It is important to know that salt always melt all the ice, so care and safety must always be taken. However we can promise 100% that we do everything possible to ensure we keep the ice to be as little risk as possible.
