Concrete Grinding After Magnesite Removal for Floor-Ready Slabs
Prepare a concrete slab after magnesite has been removed
Site issues to consider
- Magnesite removal can leave residue, uneven surface profiles, and adhesive contamination.
- New flooring may fail if the slab is not mechanically prepared to the installer specification.
- Owners need clarity on whether grinding, patching, levelling, or moisture treatment is required.
Planning the work
- We assess the post-removal slab and scope grinding around the selected floor finish.
- Surface preparation can remove remaining contaminants and expose defects that need repair.
- Handover notes help owners and flooring trades understand the prepared slab condition.
If asbestos is suspected
Do not disturb material you suspect may contain asbestos. Arrange assessment, sampling and any asbestos-related work through appropriately qualified asbestos specialists before removal or renovation proceeds.
Common questions
Is concrete grinding always needed after magnesite removal?
Not always, but it is common. The slab condition, residue, new floor system, and tolerance requirements determine the preparation scope.
Can grinding reveal concrete cancer?
Grinding can expose cracking, rust staining, and slab defects that need further assessment before covering the floor.
