Garage slab: heave, settlement and frost
Distinguish settlement, frost, poorly compacted fill, water and threshold/drainage issues before simply lifting or resurfacing a slab.
Important: this tool helps decide what to verify; it does not replace calculations, permits or professional design where required.
JAUNE / YELLOW
Seasonal movement often suggests frost/water interaction rather than progressive fill settlement.
ROUGE / RED
Slab pushing walls/door, major settlement, affected buried service or continuing movement: diagnose soil/drainage before correction.
Indicative triage
Useful tools and data
- Laser level/straightedge
- Drainage/slope map
- Seasonal history
What the professional checks
- Distinguish frost from settlement
- Check fill/drainage/services
- Select cause-compatible repair

V14
Systems to check before closing the work
V14 connects envelope, air, fire, structure, water and code instead of treating each project in isolation.
V15
Remaining system checks not to miss
V15 covers issues that can block a project, cause a loss or become expensive once concealed.
V16
Advanced diagnostics to cross-check
V16 connects water, soil, climate, safety, materials and seasonal use to existing projects.
V17
Specialized systems to cross-check
V17 completes gas, soil, water, fire, climate and structural interfaces.
V18
Specialized diagnostics to verify
V18 connects systems that become costly or regulated when a primary project triggers them.
V19
Edge systems to integrate into the project
V19 covers interfaces that become important when multiple home systems interact.
V34
Use, excavation and construction constraints
V34 connects use permits, soil, excavation, neighbouring structures and public-space logistics before hard-to-reverse work.
