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
