Blacktown
Blacktown foundation enquiries often involve northwest Sydney clay and newer raft slabs, with issues such as reactive clay movement, poor drainage, underpinning and pier settlement.
Housing and foundation context
In Blacktown, northwest Sydney clay and newer raft slabs means movement can show up as cracks, sticking doors, uneven floors or bowing basement walls — especially where drainage or moisture around the foundation has changed.
Common foundation types in the area include strip footings, pier-and-beam, waffle rafts and suspended floors. Our crews assess soil conditions, drainage and structural movement.
Guidance and next steps
Follow building-department and geological-survey guidance where published. Photograph cracks and sticking openings, note when movement started and keep drainage clear of the foundation.
We help you request an on-site foundation assessment.
