Does salt damage concrete driveways?

The answer is yes, salt does indirectly damage your concrete driveways, patios and sidewalks. Bumps and potholes don’t just appear due to regular wear and tear – salt damages concrete over time by causing corrosion to occur under the surface, leading to discolored, cracked and crumbling concrete.

How do you protect concrete from salt damage?

The only way to stop this type of damage is with a water repellent sealer, such as a siliconate water repellent or a silane siloxane water repellent. Water repellent sealers such as these form a hydrophobic barrier that caused water and other liquids to bead off the surface.

Can I put salt on my concrete driveway?

Rock salt is not only poisonous for your pets and plants but also highly corrosive. Its harmful chlorides cause health risks to children and pets—salt damages concrete driveways, patios, and sidewalks indirectly.

What kind of salt does not damage concrete?

Magnesium chloride is a great choice! While magnesium chloride is more expensive than sodium chloride and calcium chloride, it is less likely to damage your concrete or your lawn.

Does salt help melt ice?

When added to ice, salt first dissolves in the film of liquid water that is always present on the surface, thereby lowering its freezing point below the ices temperature. Ice in contact with salty water therefore melts, creating more liquid water, which dissolves more salt, thereby causing more ice to melt, and so on.
