Concrete floor levelling Brisbane
Superfloor Australia levels concrete by mechanically grinding down lippage, high spots and raised areas. The work reduces high concrete to leave the existing slab flatter and more even for the planned finish or use.
Define the requirement
Flatten the slab by reducing the high concrete
This service does not pour a new layer over the floor. Large floor grinders and edge grinding equipment remove lippage and high areas from the existing concrete until the agreed areas are flatter and more even.
Lippage at slab joints, raised edges, high spots, ridges and broad areas that sit above the surrounding floor.
Mechanical diamond grinding connected to industrial dust extraction, with smaller equipment used where the main grinder cannot reach.
Confirm the affected area, intended finish, target tolerance, access and any visible cracking or structural concerns.
Where grinding makes the difference
Target the concrete that sits too high
Mechanical levelling is a reduction process. It removes concrete from raised areas rather than filling low areas or installing self levelling compound over the slab.
Lippage reduction
Raised lips and stepped transitions at compatible concrete joints can be ground back to reduce the height difference.
High area grinding
Large walk behind grinders can reduce wider high sections and make the existing surface flatter across the agreed scope.
Edges and transitions
Smaller grinding equipment can work around walls, doorways and fixed elements where the main machine cannot reach.
Plan the correction
The slab and required tolerance set the grinding scope
The amount of concrete that can be safely removed depends on the slab, the depth of the high areas and the finish the floor needs to receive. The target should be agreed before grinding starts.
- Target flatness or transition confirmed
- Grinding depth checked against the slab condition
- Edges, drains and fixed elements reviewed
- Dust controlled access and clean up planned
Typical workflow
Measure the high areas, then grind them down
A clear concrete floor levelling scope starts with the actual height variation and the result the floor needs to achieve.
Inspect the concrete
Review the visible slab condition, lippage, high spots, transitions, cracking and site access.
Map the high areas
Identify where the concrete rises above the surrounding surface and where reduction is required.
Confirm the grinding scope
Agree the target area and outcome, with the slab condition and intended floor finish taken into account.
Grind down the concrete
Use dust controlled floor grinding equipment to reduce compatible lippage and high sections of the existing slab.
Check and clean the surface
Review the corrected areas, complete the agreed edge work and leave the floor ready for its next planned stage.
Important boundary
Grinding reduces high concrete. It does not fill low areas.
Low areas, structural movement, significant cracking, moisture or waterproofing concerns may need a different trade, product or investigation. Superfloor’s floor levelling scope is mechanical reduction of compatible high concrete.
Still removing old flooring?
Old coatings, adhesive and residue can hide the true concrete surface. Separate floor preparation may need to happen before the high areas can be assessed and ground accurately.

Questions about concrete floor grinding
Do you pour self levelling compound over the floor?
No. Superfloor Australia’s levelling service uses mechanical grinding to reduce lippage, high spots and raised areas in the existing concrete.
What is the difference between floor preparation and levelling?
Floor preparation removes adhesive, coatings or surface contamination for the next system. Mechanical levelling targets lippage and high concrete to make the slab flatter and more even. A project may need one or both services.
Can grinding correct every uneven concrete floor?
No. Grinding can reduce compatible high areas, but it does not fill low areas or resolve structural movement, active cracking or moisture problems. Those conditions may require separate advice.
How much concrete can be ground away?
That depends on the slab, the depth and location of the high area, reinforcement risk and the result the next flooring system needs. The grinding scope should be assessed before work begins.
