Concrete Resurfacing & Repair
Damaged, cracked, pitted or worn concrete may need repair or surface correction before a coating system can be considered. EPOFC assesses the condition of the slab and the intended flooring system before recommending the appropriate next step.
Cracks / Spalling / Pitting / Damaged edges / Surface correction
What Does Concrete Repair Involve?
Concrete repair addresses suitable localised defects or damaged areas identified during assessment so the floor can then be prepared for its intended use or subsequent coating system. The repair method depends on the type of damage, the condition of the surrounding concrete and the next stage of the project.
In practice that covers cracks that need assessment and treatment, chipped or spalled areas where material has broken away, damaged edges and transitions, pitted or deteriorated patches, and previous repairs that need checking. What is appropriate depends on the cause and the condition, not on the defect alone.
What Does Concrete Resurfacing Mean?
Concrete resurfacing focuses on correcting or improving the usable surface of existing concrete where appropriate. Depending on the project, this may involve localised repair or broader surface correction before a subsequent flooring or coating system. It does not mean rebuilding or structurally reconstructing the slab.
What is suitable for a given floor is confirmed after the concrete has been assessed.
Repair, Resurface Or Prepare?
These categories can overlap. The correct approach depends on the actual floor rather than the label used for the service.
Local Repair
Surface Correction
Surface Preparation
Common Floor Conditions That May Need Attention
Cracks
Cracks should be assessed, and treatment depends on the crack type and whether there is movement. Future movement may make cracking visible again.
Spalling or chipped concrete
Damaged material may require localised treatment. What is appropriate depends on the extent and the condition underneath.
Pitting or surface damage
Worn or damaged areas may require correction before a coating is considered.
Damaged edges
Edges, transitions or local breakouts may need repair depending on the flooring system selected.
Previous repairs
Existing repair materials should be assessed for condition and compatibility with the proposed system.
Cracks Are Not All The Same
Two cracks that look alike can need different work. What matters is what the crack is doing, where it sits and what is going over it.
Some cracks are stable and localised.
Some may reflect ongoing movement in the slab.
Treatment depends on the floor and the selected flooring system.
Treatment can address the existing crack or damage, but future slab movement may cause cracking or movement to become visible again.
Some cracks or movement conditions may require specialist assessment before a flooring system proceeds.
Spalled, Chipped Or Damaged Concrete
When concrete has broken away, chipped or deteriorated, the damaged area should be assessed before coating. Loose or unsuitable material may need to be removed and the area repaired or treated using a method appropriate to the damage and intended floor system.
Repair Before Coating
A coating system should not be used simply to hide defects that need attention. Where repair is required, it should be addressed as part of the preparation scope before the selected flooring system is installed.
Repair work can affect several parts of the project:
The preparation the floor needs once the repair is done.
The finished appearance, since repaired areas can read differently under a coating.
Coating continuity across the repaired and original concrete.
The overall scope of the work.
Project timing, because repair materials have their own requirements.
Repair And Preparation Work Together
Repair addresses the defect. Surface preparation then addresses the broader substrate requirements for the selected coating system.
Diamond grinding where appropriate, across the wider floor rather than only the repair.
Preparation of the existing concrete surrounding the repaired area.
The transition between repaired and original areas.
Surface condition once the repair has been completed.
Compatibility between the repair, the substrate and the coating.
How The Repair Scope Is Worked Out
Assess the damage
Review the location, extent and visible condition of the concrete.
Understand the next use
Consider whether the floor will be coated and how the area will be used.
Define the repair requirements
Identify which defects may need treatment and whether specialist input may be required.
Repair as appropriate
Carry out the agreed localised repair or surface work suited to the project.
Move to the next stage
Once suitable, preparation and the selected flooring or coating process can continue.
What Surface Repair Does Not Automatically Fix
Surface repair can address suitable localised defects, but it does not automatically resolve deeper structural or building-related conditions. Where the condition falls outside the scope of flooring-related repair, specialist assessment may be required.
Active structural movement
Foundation problems
Major slab movement
Significant structural deterioration
Ongoing moisture problems
Reinforcement corrosion
Unknown hazardous materials
What Condition Is The Floor In?
Damaged floors start in very different places. Five common starting points are shown below.
Minor local damage
May be suitable for localised assessment and repair ahead of the next flooring stage.
Multiple cracks or damaged areas
May require broader assessment before deciding the repair and preparation scope.
Worn or pitted surface
May require surface correction and preparation depending on the condition of the concrete.
Previously repaired floor
Existing repairs should be assessed for condition and compatibility with the proposed system.
Unknown condition
Send photos and project details. Customers do not need to diagnose the slab themselves.

What If The Damage Looks Structural?
EPOFC’s focus is flooring-related concrete repair, surface preparation and coating work. Where cracking, movement or deterioration appears to involve a structural issue, specialist assessment may be required before flooring work proceeds. Send photos through and the appropriate next step can be discussed.
Frequently Asked Questions
Can cracked concrete be repaired before epoxy flooring?
Often, once the cracks have been assessed. Cracks and damaged concrete are repaired or treated where required, while joints are assessed and handled according to the selected flooring system.
Will repaired cracks ever come back?
Treatment can address the existing crack or damage, but future slab movement may cause cracking or movement to become visible again. Where movement is suspected, that is worth raising before flooring work proceeds.
Can spalled concrete be repaired before coating?
Where concrete has broken away or chipped, loose or unsuitable material may need to be removed and the area repaired or treated using a method appropriate to the damage and intended floor system. The extent and the condition underneath decide what is suitable.
Can pitted concrete be coated?
It depends on how deep and widespread the pitting is. Some floors may need surface correction before coating, while others may only require appropriate preparation before the selected coating system is installed. The floor should be assessed either way.
Can you coat over damaged concrete?
A coating system should not be used simply to hide defects that need attention. Where repair is required, it should be addressed as part of the preparation scope before the selected flooring system is installed.
What is the difference between concrete repair and resurfacing?
Repair addresses localised defects or damaged areas. Resurfacing focuses on correcting or improving the existing floor surface more broadly. Surface preparation is different again: it prepares the substrate for the selected coating system.
Does concrete need to be ground after repair?
Whether mechanical preparation is required depends on the repair, surrounding concrete and selected coating system. Preparation usually covers the wider floor rather than only the repaired area.
Can an old concrete floor be resurfaced?
Sometimes. It depends on the condition of the slab, how widespread the wear or damage is and what the floor needs to do afterwards. Some older floors suit surface correction and coating, while others need more work first.
Can you repair structural cracks?
Where cracking appears structural or movement-related, specialist assessment may be required before flooring work proceeds. EPOFC's focus is flooring-related concrete repair, surface preparation and coating work.
How long does concrete repair take?
Timing depends on the type and extent of repair, preparation requirements, repair materials used and the next flooring stage. Indicative timing is provided once the floor has been assessed.
Can you quote from photos?
Photos help with an initial review, particularly close-ups of cracks, damaged areas and existing coatings. They may not replace an inspection, since the surrounding concrete and underlying condition also matter.
Do you repair garage floors?
Garage floor repair forms part of the flooring work, commonly covering cracks, chipped edges, worn concrete and localised damage ahead of a coating.
Do you repair commercial concrete floors?
Flooring-related repair on commercial and higher-use floors is within the service structure. Larger floors are assessed across the whole area, since worn traffic areas and existing repairs can vary from one section to another.
Do you service Brisbane, Gold Coast, Logan and Ipswich?
Yes, those four areas are the current service area. If your project sits outside them, send through the suburb or postcode and current service availability can be confirmed.
From Repair To The Finished Floor
Once suitable repairs and preparation are complete, the project can move into the selected flooring or coating stage where appropriate.
