Salt is definitely the number one enemy of concrete. Salt damage to concrete is widespread and common. Yet every winter we spread ice meltigypsum mine mining machine in orissang salt compounds all over our streets, sidewalks, driveways, stairs and walkways as if concrete salt damage was of no concern at all. There is a choice to make between safety and appearance, and safety wins every time. Drivers and pedestrians need to be the priority. So, out comes the salt trucks, the trips to the hardware store for ice melting products and for three or four months every year we bombard our concrete with enemy number one: salt. And concrete salt damage is the inevitable result.

Even if you choose not to salt your own property, salt finds its way into your concrete driveways, concrete garage floors, and walkways. As the salt melts the ice and snow on the roads, the slush is transferred to the underside of a vehicle and onto its tires. When the vehicle pulls into your drive and parks in your garage, the slush drips off the vehicle, and soaks right into the concrete. Salt is then stepped on and carried by shoes and boots to all the nearby walkways. And now the problems begin.

Concrete is the oldest man-made building material on the planet. It is made from easily found natural materials and is considered to be hard and durable. But one look at a salt damaged concrete walkway can tell you that this notion of "hard as concrete" has some holes in it... literally.

The problem is actually in the chemistry. Without getting all scientific and technical, it can be explained this way: do you remember learning about pH in school? PH is the measurement of alkaline/acid. Concrete is naturally very alkaline, being made up of lime, sand, stone... and has a very specific optimum pH range to maintain its strength, hardness, and cohesion. When a highly acidic compound is introduced into the concrete, the pH level is thrown completely out of whack and the concrete begins to deteriorate....
