When should I add salt to my driveway?

Rock salt is meant to be put down before snow falls, and keeps it from sticking to the surface, says Nichols. “But most people shovel, get it clear, then put down the salt. If you salt and then get snow on top it can turn to mush underneath and then it gets hard to shovel.”

Salt products do provide ice control, but many of the products on today’s market attract water to the surface long after the ice has been removed.

What is the lifespan of concrete?
