What we can help with
Grinding removes material from the surface of a concrete slab. It can reduce local high spots and ridges, remove surface residue and prepare the floor for the next stage. The amount of material removed depends on the slab and the finish required.
High spots are different from low spots
Grinding takes material away. It does not fill dips, correct every level difference or repair movement in a slab. Some floors also need patching or levelling compound, which should be agreed with the installer as part of the preparation scope.
What to send
Send your suburb, approximate area, photos of the slab and the next floor finish. Include access details, available power and the date you need the floor ready. We’ll confirm the grinding scope and what is included before booking.
Which kind of grinding do you need?
- Local high spots: raised areas, ridges and lips that need reducing. Mark the problem areas and include a photo showing the surrounding floor.
- Surface removal: glue, paint or a coating left on the slab. See adhesive and coating removal for the details to send.
- Preparation for new flooring: grinding to suit the next installation. Share the installer’s requirements for concrete floor preparation.
- Exposed concrete: if the slab will be the finished floor, compare grind and seal with mechanically polished concrete.

Common questions
Can you grind just one high spot or a slab join?
Small areas are welcome. Send the suburb or town, photos and the approximate size of the affected area. The amount that can be removed and the handover condition need to be assessed for that slab.
Is concrete grinding the same as polishing?
No. Grinding can be a preparation step before another floor is installed. Mechanical polishing involves further refining the concrete as a finished floor; grind and seal is another finish with a different scope.
