How melt products work
Ice melt has to dissolve into a brine that lowers the freezing point of water. If the pavement and air are colder than the product can handle, crystals sit on the ice like gravel with better marketing. Labels list effective temperature ranges for a reason.
Edmonton regularly sees stretches where overnight lows sit far below what basic rock salt can manage. Plan for that instead of dumping more bags on inert ice.
Rock salt limits
Sodium chloride is cheap and common. It helps in milder cold and on fresh thin ice. It also corrodes metal, stresses concrete when overused, and leaves brine that can refreeze when temperatures crash again.
After a warm afternoon melt, a cold night can turn treated surfaces glassy. That is when people think salt "failed," when the weather simply moved past its useful range.
When sand wins
Sand and similar grit do not melt ice. They add friction so feet and tires can bite. In deep cold, that is often the safer immediate fix for steps, sidewalks, and lot entrances.
Sweep up excess in spring so it does not choke gardens and drains. Commercial sites often schedule sanding with clearing; see sanding and salting for how we pair treatments with plough work.
A practical combo approach
- Clear snow first so you are not melting a full blanket
- Apply melt in the temperature window on thin ice and high-traffic paths
- Switch to sand when products stop reacting
- Revisit after freeze-thaw nights when polished ice returns
Property managers should put this logic into the seasonal agreement so crews are not guessing. The contract checklist covers how to write sanding rules down.
Surfaces and pets
Over-salting chews at concrete and metal thresholds. Use the lightest effective amount, keep piles of product off landscaping, and rinse entries when spring arrives. Pet owners often prefer sand near doors and save melt for the public walk.
