Ostanes Engineering provides certified structural engineering solutions for foundation subsidence, tailored to Brisbane’s specific soil conditions and environmental factors.
Structural Engineering Challenges for Sinking Foundations in Brisbane
Foundation movement can have several causes, including moisture change in reactive clay, fill settlement, drainage or leaks and tree influence. Several causes may need to be assessed. Level surveys, monitoring and soil information may be recommended depending on what the inspection finds, and any repair options are considered only after the cause is understood.
Documentation for Your Approval Process in Brisbane
- Subsidence investigation report
- Level survey analysis (where recommended)
- Repair or underpinning design, if required, is a separate scope and is quoted separately from the inspection
This documentation supports decisions about foundation repairs.

Designed to Strict Australian Standards (AS)
All structural assessments and underpinning designs for foundation subsidence comply with the National Construction Code (NCC).
- AS2870-2011: Residential Slabs and Footings
- AS2159-2009: Piling – Design and installation, relevant where piled underpinning is assessed
- AS3798-2007: Guidelines on Earthworks for Commercial and Residential Developments
These standards ensure that all our designs meet rigorous criteria to effectively address foundation issues.
