De-icing salts: concrete, corrosion and scaling
Reduce chloride exposure and recognize when scaling/cracking may hide reinforcement corrosion.
VERT / GREEN
Use the minimum salt compatible with safety and prevent salty water from ponding.
JAUNE / YELLOW
Concrete, steps, garages and metal repeatedly exposed to chlorides can deteriorate faster.
ROUGE / RED
Spalling with exposed/rusted steel, salted young concrete or section loss: diagnose before simple resurfacing.
Quick triage
What the professional checks
The concrete specialist distinguishes freeze-thaw, chlorides, poor curing and corrosion, then defines compatible preparation, repair and protection.
