Cracked Driveway due to Subsidence
Cracked Driveway due to Subsidence is a high-severity soil & foundation defect SURE inspectors have documented across 5 inspection reports.
Causes
- Nature of the foundation material on which the building in resting
- Soil settlement or erosion beneath the path
- Moisture fluctuations in surrounding soil
- The site landscape and topography
- Inadequate sub-base compaction
Symptoms to look for
- Unevenness, sinking, or displacement of path sections
- Large visible cracks (>15mm) on the path surface
- Evidence of ground subsidence
- Visible cracks in brick fence
- Visible cracks in driveway
Remedies
- Consult a structural engineer to determine the significance of the cracking and recommend appropriate rectification
- Investigate the root cause of the subsidence (e.g., soil tests, drainage assessment)
- Repair or replace the affected path sections after addressing the subsidence
- Contact a structural engineer for assessment and recommendations
- Consult a structural engineer to determine significance

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.
