Concrete grinding removes high spots; concrete levelling builds up low areas. Some floors need both. Before choosing a method, establish what is uneven, what finish is planned and whether the concrete needs repair first.
For builders, strata managers and property owners across Sydney and Western Sydney, the useful starting question is: what does this floor need to achieve?
Grinding or levelling: a quick comparison
| Question | Concrete grinding | Concrete levelling |
|---|---|---|
| What does it do? | Removes material from the surface. | Adds a suitable material to build up low areas. |
| When might it suit? | Local high spots or surface preparation. | Depressions or areas requiring a suitable base for floor finishes. |
| What needs checking? | Slab condition, removal limits and the required surface profile. | Substrate condition, product suitability and available build-up height. |
When concrete grinding may be suitable
Concrete grinding may help address surface irregularities or prepare concrete for a coating or floor covering. It does not fill depressions or fix ongoing slab movement. The intended finish and project specification should guide the preparation method.
When to discuss concrete levelling
If the problem is a low area, ask PPS about concrete levelling. The appropriate approach depends on the existing floor and the proposed finish. Include any floor-finish specification with your enquiry so the requirements can be reviewed together.
Do cracks or movement need attention first?
Do not choose a cosmetic treatment solely from a photograph when cracks, movement or deeper defects may be involved. Ask whether assessment or concrete repair work is needed before surface preparation proceeds.
What to send with your enquiry
- The site suburb and approximate floor area.
- Wide photographs showing the whole floor, plus close-ups of affected areas.
- Available measurements showing the location and extent of unevenness.
- The intended floor covering or coating, including its specification if available.
- Access details, occupied areas, working-hour restrictions and your programme.
- Any previous repair information or inspection reports.
Describe the result you need rather than requesting a treatment before the floor has been assessed. For example: “We are preparing this area for a new floor finish and need advice on the high and low sections.”
Frequently asked questions
Can one floor need grinding and levelling?
Yes. A floor can have both high and low areas. The scope should be based on its condition and the requirements of the proposed finish.
Can PPS quote from photographs alone?
Photographs and measurements help start the discussion. PPS can advise what further information or site assessment is needed before confirming a scope.
