In climate zones, exposed to frost and thaw, the stone surface is permanently stressed. Usually limestone is more sensitive to frost than hard stones (e.g. granite). To protect the stone against chipping and weathering, an impregnation is highly recommended. The impregnation will keep the vapour permeability of the stone.
