Shed Slab Cracking
Shed Slab Cracking is a moderate-severity soil & foundation defect SURE inspectors have documented across 6 inspection reports.
Causes
- Building settlement
- Ground movement
- Differential settlement of foundations
- Curing shrinkage of concrete
- Settlement
Symptoms to look for
- Cracking to slab (0-2 category)
- Doors binding or out of square
- Visible cracks in the concrete slab
- Cracking in the slab (category 0-2)
- Slab cracking
Remedies
- Monitor cracks and engage a structural engineer if cracks increase
- Engage a concreter to repair
- If cracks increase in size, further investigation should be carried out by a structural engineer
- Monitor cracks
- Engage a concrete contractor for advice and repair
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.
