Hawthorn and Camberwell are experiencing a trend of luxury home developments featuring deep basements, often two or more levels deep. These excavations in the suburbs’ reactive clay soils present significant risks to neighbouring properties.
The Basement Trend in Hawthorn and Camberwell
High land values in these established suburbs drive developers and homeowners to maximise building footprints by going underground. Basements for garaging, living spaces, and home theatres are increasingly common, each requiring significant excavation. We connect you with specialist inspectors experienced with basement excavation impacts in these suburbs.
Specific Risks
- Deep excavation in reactive clay causing settlement of adjacent properties
- Dewatering lowering the local water table and drying out clay soils
- Retaining wall construction generating vibration near boundaries
- Loss of mature vegetation from changed soil moisture conditions
- Long construction timelines extending the risk period
Understanding Reactive Clay Soils
The reactive clay soils common in Hawthorn and Camberwell shrink when dry and swell when wet. Excavation can alter the moisture balance in surrounding soil, triggering movement that affects foundations and structures beyond the construction site. Read more in our soil and foundation articles.
