De-icing products are vital in many settings such as pavements and driveways so that people don’t slip. We know a fair bit about rock salt, a common choice which can have negative effects on concrete surfaces. It is important to understand this so that you know the best way to prevent ice without causing damage in the process. You should also look into less harmful alternatives to rock salt.
People apply rock salt to a surface because it lowers the freezing point of water. This is important to keep in mind because it will only work to a certain temperature but if it lowers further, it will freeze again. As a result slipping becomes a problem again if the weather gets worse.
Using rock salt on concrete can be a very bad decision. This is because it is a porous material which will absorb water. The salt and water mix that lays on the surface in cold weather will be absorbed. If the temperature remains low, it can then freeze and expand. This results in hydraulic pressures which can exceed the compression strength of the concrete, causing damage. The likelihood of this will increase when the freeze/thaw cycle continues.
You also need to note that rock salt is hydroscopic so it will attract water. This will end up in the concrete and as it freezes and thaws, there will be additional hydraulic pressure. This pressure is upward and will lead to spalling, ruining the surface.
You still need to use something to stop surfaces icing over and becoming slippery. Our products aren’t corrosive or harmful to pets and will prevent water re-freezing. We are proud to offer alternatives to rock salt that won’t damage concrete surfaces.
