Pass on the salt - try grit instead

If you need to de-ice pavements that run alongside stone or brick buildings, try using grit instead of pounds of salt, which works itself into stone pores and, in the worst cases, can cause complete structural disintegration. Limestone is particularly susceptible. Dissolved road salt causes problems by migrating through the masonry with rising damp, typically visible as a 'tide mark' of staining above ground level. So avoid near historic buildings if possible.
