No — Expandify homes cannot be installed on concrete strip footings or slabs. All homes must use the engineered steel stump system included with the design.

Expandify’s exclusive footing system uses adjustable galvanised steel stumps, which:

Allow for elevation and levelling on various site slopes

Are engineered to suit H1-class soil as standard

Can be upgraded to suit H2, M, or P-class soil types

Provide airflow and moisture control beneath the dwelling

The system is certified and compliant with NCC footing and subfloor requirements. Alternative foundation systems such as concrete strip footings are not permitted and would void compliance and warranty.
