Rock salt is mined sodium chloride (NaCl) — the de-icer that clears the majority of Canada's roads, parking lots and sidewalks every winter. Its appeal is simple economics: it is the lowest-cost de-icer per tonne and melts ice effectively down to about −9 °C, which covers most events through much of the country. Working range runs to about −9 °C, with bulk delivery by the tonne and 20 kg bags on pallets.
For high-volume road and lot work, nothing beats it on price. Crews spread it mechanically at maintenance rates, and pre-wetting it with liquid brine keeps the granules on the road instead of bouncing into the gutter, so each tonne goes further and the melt starts sooner.
Its limit is deep cold: below roughly −9 °C rock salt slows and then stops, so winter programs in cold regions keep calcium chloride on hand for the coldest nights, bridge decks and priority surfaces while rock salt carries the bulk of the season.
Chloride.ca supplies bulk road salt for municipalities and snow-and-ice contractors and palletized bagged rock salt for properties and walkways, delivered to every province and territory on contract volume pricing. Order bulk for the yard and bags for the truck on a single delivery — call for a same-day quote.
salt and refined sodium chloride are the same compound, but the mined de-icing grade is coarser and less pure than the treatment grade used in softeners — which is exactly what road work wants, since purity is irrelevant on pavement and the lower price is what matters at high volume. We supply the de-icing grade sized for spreaders and storage.
