Magnesite removal Sydney for apartment slabs and strata fit-outs
Magnesite removal in a typical Sydney apartment takes 2–4 days, depending on thickness (commonly 30–60 mm), reinforcement mesh, and the level of slab repair required afterwards.
Magnesite was a popular underlay in Sydney apartments built between 1960 and 1985, but it absorbs moisture and corrodes the slab below. Our removal service handles full demolition, slab inspection, rust treatment, and the levelling required to prepare for modern finishes — with strata-friendly scheduling and dust control.
What this service delivers
- Full magnesite demolition with mesh and rust assessment
- Slab repair and corrosion treatment where needed
- Self-levelling pour to restore a finish-ready substrate
Frequently asked questions
- How do I know if my Sydney apartment has magnesite?
- Magnesite is usually 30–60 mm thick, dark grey or brown, and crumbles when scratched. It is most common in apartments built between 1960 and 1985 in Sydney.
- Why is magnesite a problem?
- Magnesite absorbs moisture and releases chlorides that corrode the slab reinforcement. Left in place, it can cause structural concerns and finish failures.
- How long does removal take?
- Most one-bedroom and two-bedroom apartments are stripped, repaired, and levelled within four to seven working days.
- Will removal damage the slab?
- Removal exposes existing condition. We document any corrosion or honeycombing before specifying targeted repairs and a structural-grade levelling compound.
