Vegetation Proximity to Building
Vegetation Proximity to Building is a moderate-severity soil & foundation defect SURE inspectors have documented across 15 inspection reports.
Causes
- Proximity of trees to the building foundations
- Proximity of trees to the building
- Proximity of trees to dwelling
Symptoms to look for
- Potential future wall cracking due to root impact/soil movement
- Currently no visible defects or wall cracking caused by trees
- No visible defects/wall cracking currently
Remedies
- Monitor and maintain existing vegetation (including roots) to ensure no future impact to the building
Worth asking our inspector about this specifically.
This is common across Perth stock and usually fixable without drama, but the scope of the fix varies. Every SURE inspection includes 12 months of free advice. Call out the defect by name and we check for it directly.
Curated entries in Soil & foundation
- Curated 1–4/5Trees in Close Proximity to Dwelling
Large trees within the foraging radius of the dwelling - typically any tree within 3 m for small species, or within 10 m for large eucalypts - introduce two distinct risks: root-driven soil moisture fluctuation that causes differential footing movement on reactive clay, and a direct termite foraging corridor between a timber food source in the crown or root system and the building structure. Neither defect is always present, but the proximity constitutes a conducive condition that warrants ongoing monitoring.
- Curated 2–5/5Reactive Clay Soil Movement Affecting Foundation
Seasonal expansion and contraction of reactive clay soils causing cyclical foundation movement, wall cracking, and floor level changes. Prevalent in Sydney Western Suburbs and some Perth clay zones. Severity depends on soil class (H, H1, H2, E) and footing design adequacy.
