Soil, slabs and movement in Deanside VIC
Deanside sits on the volcanic plains west of Melbourne, where the clay soils are often reactive: they swell when wet and shrink when dry. Your lot's site class under AS 2870 is on the soil report and engineering, and it sets how the slab is designed. Once the house is built, how water is managed around it decides how much it moves.
Check the soil report for your lot's site class before the slab is designed.
At slab stage, the extra bars in wide ribs and the cover under the steel are what we look at most closely.
Keep ground falling away from the house and downpipes connected to stormwater.
Garden beds and heavy watering hard against the slab edge invite movement.
Diagonal cracks from window and door corners are the classic sign of ground movement.
