Photograph with scale and date observations.
Foundation cracks: track movement before repair
Distinguish stable cracking, leakage and active movement using photos, width, dates and related symptoms before hiding evidence.
Important: this tool helps decide what to verify; it does not replace calculations, permits or professional design where required.
JAUNE / YELLOW
A changing crack, sticking doors or distorted floors can indicate broader movement.
ROUGE / RED
Rapidly widening crack, bowed/displaced wall, settlement or major leakage: professional assessment before injection/patching.
Indicative triage
Useful tools and data
- Ruler/crack gauge
- Dated photos
- Levels/reference points as appropriate
What the professional checks
- Characterize movement and cause
- Cross-check soil/drainage/structure
- Select repair after diagnosis
