Can existing engineered stone still be modified?

Understand the distinction

The prohibition on engineered stone benchtops, panels and slabs is separate from permitted work on legacy installations. Limited repair, minor modification, removal and disposal work may be permitted subject to applicable conditions. A new layout or substantial alteration should not simply be described as a minor change without assessment.

Check the state requirements

Requirements include controlled processing and regulator notification where applicable. SafeWork NSW provides an annual notification process for intended processing of legacy engineered stone. Queensland work must be considered against Workplace Health and Safety Queensland’s requirements. The business carrying out the work must establish its obligations before starting.

Identify the material

A brand name or a photograph may not identify the composition. Provide original product documents and the installation date if known. Porcelain, sintered surfaces and newer zero-silica products are not assumed to be the same material as older resin-bound engineered stone.

Ask about the actual proposed job

Send the existing and proposed opening sizes, appliance manual and photos of the surrounding support. We assess the specific scope rather than promise blanket suitability. Never attempt a dry trial cut or grind the surface to identify it. Consult the linked regulators for current requirements.
