Permafrost and northern home foundations

In northern regions, monitor thaw-related settlement/heave and avoid treating foundations as if soils were temperate.

VERT / GREEN = documenter · JAUNE / YELLOW = vérifier · ROUGE / RED = arrêter/faire valider.

Rapid settlement or building tilt
Assess stability and ground conditions before improvised levelling. Drainage/heat changed near foundation
Assess thermal and moisture effects on frozen ground. Addition planned on permafrost
Require site- and future-climate-specific design. Movement monitored over time
Keep benchmarks, photos and seasonal level readings.

What the professional checks

Characterize ground, temperature and movement
Design foundation/ventilation/drainage for site
