Most of inner Melbourne sits on reactive clay soils. If unsure, select "Clay" or "Mixed".
Understanding Excavation Risk in Melbourne
Melbourne is built predominantly on reactive clay soils, which are particularly susceptible to ground movement during nearby excavation. Basement construction, underground car parks, swimming pool excavation, and deep service trenches can all impact neighbouring properties.
Key Risk Factors
The distance between your property and the excavation is the single most critical factor. Properties within 10 metres are at highest risk. Excavation depth matters too — anything deeper than 3 metres significantly increases the zone of influence.
Older buildings are more vulnerable because they typically have shallower foundations and may have existing structural weaknesses that excavation can exacerbate. Melbourne's reactive clay soils can shrink and swell dramatically, amplifying the impact of nearby ground disturbance.
