Refrain From Salt-De-Icers: Salt will damage pavers, causing them to start eroding. The purpose of the salt is to melt the snow but the salt doesn’t wash away easily. It stays on the stones and refreezes because the temperature remains below freezing for so long. The cycle restarts itself every time salt is added to de-ice your driveway, walkway, and patio. As the salt builds up, the salt/snow mixture will expand causing discoloration, flaking, erosion, and other problems.
