As some of you know. Applying Rock Salt to either old concrete or new in excess or at all may damage your concrete. If you have a new installation it is not recommended that you use salt within the first year from the date of installation.
New concrete may be de-iced using what is called Mag Ice. This product can be purchased at Home Depot or your local concrete supplier. It is the safest way to melt ice on new and old concrete.
Unfortunately in some areas of the country State and Local Governments are using a liquid salt that may be brought in on your car without you knowing it. This is extremely caustic and will ruin both old and new driveways that are even sealed.
Prosoco makes a product called Salt Guard that has been showing some good results as a protective measure against salt damage. It is easily applied and can make a difference.
