VERT / GREEN
Define truly critical zones and drainage before sizing.
Heated driveway and snowmelt system
Compare electric/hydronic, slab, drainage, sensors, power, energy and meltwater destination before embedding the system.
JAUNE / YELLOW
The system turns snow into water: without proper grade/outlet it can shift the problem to ice or the foundation.
ROUGE / RED
Cables/tubing in existing slab, high electrical load or drainage to neighbour/street without review: professional design.
Interactive triage
Helps choose the next step; does not replace design, permits or professional diagnosis.
Useful tools and data
- Area/power
- Slab/joint plan
- Grades/outlet
What the professional checks
