Dealing with snow and ice on Imprinted Concrete Paving
Published on 13th Dec 2013.
With regards to your Imprinted Concrete during icy and snowy conditions it is ok to use small amounts of salt if conditions are very bad but the problem arises when we get a cold and dry spell like the winter of 2010 as the surface doesn’t get rinsed off and the salt is in contact with the concrete for long periods.
Coarse sand is a good alternative to give some grip to the surface of the snow / ice; you just have to make sure it hasn’t frozen into a big lump when you come to use it. As we know conditions can be quite different so there is no straight answer but I would tend to use the rule that if it is very cold and dry as last winter then sand would be the answer and if it is cold and wet the salt would be acceptable.
Another factor to consider is whether your sealant is up to date as then the salt is less likely to cause problems aswell. If the surface hasn’t been sealed in the last few years and is looking dull and worn then it is better to avoid the use of de-icing salts as this may result in corrosion of the Decorative Concrete surface as the concrete surface will be lacking in its protective Sealant.
I hope this helps to keep you safe.
