Our Floor Levelling Process
At Concrete Cancer Repairs Sydney, we follow a detailed, step-by-step approach to ensure every floor is level, stable, and ready for installation.
Initial Surface Preparation:
We start by thoroughly cleaning the existing subfloor. All dust, glue, coatings, and loose materials are removed to create a clean base. This foundational step is essential for achieving strong adhesion with any levelling products applied afterwards.
Precision Concrete Grinding:
Using professional-grade grinding machinery, we remove uneven areas and high points across the slab. This not only creates a consistent surface but also improves the bond between the concrete and the levelling materials.
Priming the Substrate:
A high-quality primer is then applied to seal the surface and promote a secure connection between the concrete and the levelling compound. This helps prevent moisture issues and ensures long-term performance.
Applying Self-Levelling Compounds:
We use premium self-levelling products—such as those from Ardex or Ardit—to produce a perfectly smooth and even finish. These compounds are suitable for a wide variety of floor coverings, including vinyl, timber, carpet, tile, and more.
Final Quality Check:
Once the levelling compound has fully set, we carry out a comprehensive inspection. This final assessment ensures the floor meets industry standards and is completely ready for the next stage of installation.

How Much Does Floor Levelling Cost In Sydney?
For most projects completed by Concrete Cancer Repairs Sydney, the cost of professional floor levelling generally falls between $40 and $65 per square metre. The final price depends on the level of preparation required, the condition of the existing surface, and the finish you need for your flooring system.
Key Factors That Influence Floor Levelling Costs:
SIZE OF THE AREA:
Larger floor spaces usually benefit from a lower cost per square metre, as materials and labour can be used more efficiently across a wider area.
TYPE OF SUBFLOOR:
Different subfloors—concrete, timber, particleboard, or damaged slabs affected by concrete cancer—require different preparation methods.
LEVEL OF UNEVENESS:
Floors with significant height variations, dips, or raised sections will require more levelling compound and additional labour. The more correction required, the higher the overall cost.
PREPARATION WORK:
Concrete grinding, removing weak and drummy concrete as well as repairing concrete cancer can increase the final price.
FLOOR CONDITION:
If the slab is damaged, cracked, or showing signs of concrete cancer, additional repairs may be needed before levelling can begin. The better the underlying structure, the lower the overall cost. Poor slab condition typically increases both labour and material requirements.
Will I Need Concrete Grinding Before Levelling?
Yes, Concrete Grinding is often an important step before installing a floor levelling compound, but it isn’t always mandatory. The need for grinding depends entirely on the condition of your existing slab and the level of preparation required to achieve a durable, long-lasting finish.
In many cases, grinding is essential because it removes high spots, opens surface pores, and creates a clean, bond-ready surface for the levelling compound. If the concrete has coatings, glue, paint, epoxy, old tile adhesive, or surface contaminants such as oil, dust, or laitance, grinding ensures these issues are eliminated so the levelling product adheres correctly.
Concrete grinding is also recommended when the slab has cracks, surface damage, or areas of weak or crumbling concrete, as it exposes a solid foundation for repairs and levelling.
However, concrete grinding isn’t always required. If your slab is already clean, structurally sound, and reasonably flat, lighter preparation may be sufficient. Some modern primers and high-quality self-levelling compounds can bond effectively to slightly uneven or textured concrete, reducing the need for heavy grinding.
A professional assessment is the best way to determine the right approach and ensure a flawless levelling result.
How Long Is The Floor Leveling Process?
The Floor Leveling process, from start to finish, can take anywhere from a few hours to a few days, depending on the size of the project, the type of leveling compound used, and the desired outcome. Typically, a standard residential property can be leveled in 1 to 3 days.
Here’s a more detailed breakdown:
PREPARATION:
This initial step, which includes cleaning, priming, and repairing any cracks, can take several hours, especially if extensive preparation is needed.
APPLICATION:
Self-leveling compounds can be applied and begin to dry within a few hours.
CURING:
Most leveling compounds are ready to walk on within a few hours, but it’s recommended to allow them to cure for 24 hours before installing any floor coverings, like tiles or carpets.
ADDITIONAL FACTORS:
Factors like the thickness of the leveling compound, the temperature, and humidity can affect the drying and curing times.
Types Of Floor Levelling Services We Provide
We deliver a complete range of professional floor levelling solutions designed to suit every subfloor condition and project requirement. Our team assesses your surface and recommends the most effective method to ensure a perfectly flat, durable, and installation-ready finish.
SKIM COATS:
Used for minor imperfections, skim coats apply a thin, refined layer over the surface to smooth out light dips, scratches, or inconsistencies. This creates an ideal base for installing new flooring materials.
FULL FLOOD COATS:
When a slab has noticeable unevenness or widespread height variations, a full flood coat is applied across the entire room. This method ensures a uniform, level surface from wall to wall and is commonly used before installing vinyl, hybrid, carpet, or tiles.
LIQUID SCREEDS:
Liquid screeds are a fast-curing, highly efficient levelling option ideal for larger spaces. They flow naturally across the surface, settling into low areas and producing a smooth, consistent finish with excellent strength.
TRADITIONAL SCREEDS:
Our traditional sand-and-cement screeds offer a strong, load-bearing subfloor solution. This method is perfect for areas that require additional durability, thickness, or gradient control and is a popular choice in both residential and commercial settings.
RAMPING AND FALLS TO DRAINS:
For wet areas such as bathrooms, laundries, and balconies, we can create custom ramps and precise falls to ensure correct water drainage. This helps prevent pooling, moisture issues, and future damage while meeting building standards.
Can You Provide And Install Underfloor Heating Systems?
Yes, at Concrete Cancer Repairs Sydney, we also offer professional underfloor heating installation as part of our floor preparation services. If your project requires heating beneath the finished flooring, our team can supply and install the system before applying any levelling compounds.
We ensure the heating elements are positioned correctly, fully encapsulated, and protected with a precision-applied levelling layer. This guarantees even heat distribution, long-term performance, and a perfectly smooth surface ready for your final floor covering.
Are Floor Levelling Compounds Suitable for All Subfloor Types?
Yes, modern floor levelling compounds can be applied to a wide variety of subfloors, not just concrete slabs. The preparation process will differ depending on whether the base is concrete, timber, or an existing floor surface, but with the correct primers and sealants, most substrates can be successfully levelled.
For example, a properly sealed concrete slab generally only requires the correct primer before a self-levelling product is poured. Timber subfloors, however, need additional preparation such as sealing, strengthening, or waterproofing to ensure the levelling compound bonds correctly and performs long-term.
Common Subfloors That Can Be Levelled
Floor levelling systems are compatible with a wide range of surfaces, including:
1) Concrete Slabs
2) Timber and Wooden Flooring
3) Existing Tiles
4) Particleboard
5) Plywood
Exception that is not be suitable for levelling:
– Self-levelling compounds NEVER never be applied over Magnesite Flooring, as magnesite is unstable, moisture-sensitive, and can break down beneath the levelling material, leading to failures.
Why Is Floor Levelling Required?
Floor levelling is a crucial step in any renovation or flooring installation project. It ensures durability, safety, comfort, and long-term performance. Here are the top reasons floor levelling matters:
PROPER INSTALLATION OF FLOORING:
– Laminate, vinyl, tile, and hardwood floors all require a flat, even subfloor.
– Uneven surfaces can cause planks or tiles to shift, crack, separate, or become loose over time.
PREVENTING STRUCTURAL ISSUES:
– Uneven floors may indicate deeper problems such as foundation movement, water damage, or subfloor deterioration.
– Levelling helps detect and correct these issues before they worsen and lead to expensive repairs.
IMPROVED SAFETY:
– Sloped or uneven floors are a tripping hazard—especially for children, seniors, and anyone with mobility challenges.
– A properly levelled floor creates a safer environment throughout your home.
LONGER FLOOR LIFESPAN:
– Flooring installed on an uneven surface wears out faster and is more prone to damage.
– Levelling provides a stable, uniform base that extends the life of your flooring.
ENHANCED COMFORT:
– Walking on uneven floors can feel awkward, unstable, and uncomfortable.
– A level floor ensures a smooth, pleasant, and consistent experience underfoot.
INSTALLED RIGHT THE FIRST TIME:
– Proper levelling is essential for the long-term success of any flooring installation.
– Dips, humps, and visible high spots can be distracting and unattractive.
– Skipping levelling can result in early failures and costly repairs.
WARRANTY PROTECTION:
– Most flooring manufacturers require a level subfloor for their warranty to remain valid.
– Poor levelling—or skipping it entirely—can void your warranty.
PROFESSIONAL QUALITY OVER RISKY SHORTCUTS:
– Expert levelling ensures durability, precision, and peace of mind.
– Work done by unqualified contractors can lead to cracking, lifting, or total flooring failure—with no warranty coverage.
ELIMINATES FLOOR SQUEAKS AND MOVEMENT:
– Uneven or poorly supported subfloors often cause squeaking, shifting, or “bouncy” spots.
– Proper levelling fills gaps, stabilizes the floor, and ensures your flooring feels solid, quiet, and secure underfoot.
PREVENT FLOORING FAILURES:
– Skipping this crucial step can lead to premature issues and costly repairs.
There’s nothing like the smooth, even feel of a professionally levelled floor. Done correctly, it enhances comfort, usability, appearance, and longevity. Done poorly, it can leave your new flooring unstable and prone to damage. Proper floor levelling is one of the smartest investments you can make for a beautiful, durable, and trouble-free floor.
How Thick Can Self-Levelling Concrete Be Applied?
The allowable thickness for self-levelling concrete varies widely depending on the product formulation, brand, and purpose. Each manufacturer sets its own limits, but there are industry-standard guidelines that help determine what can be achieved in a single pour.
STANDARD POUR MAXIMUM THICKNESS:
Most self-levelling compounds can be installed at:
– 6 mm to 25 mm (approximately 1/4 inch to 1 inch) in one application
– Some premium or heavy-duty products can be applied up to 38 mm (around 1.5 inches)
These products are designed to flow, fill dips, and create a smooth, level surface without compromising strength.
MAXIMUM THICKNESS IF AGGREGATE IS ADDED (such as pea gravel):
When deeper levelling is required, many self-levelling compounds can be extended with clean pea gravel. With the correct mix design, this allows applications of:
– 50 mm to 125 mm (2 to 5 inches)
This method is commonly used for heavily uneven slabs or areas requiring substantial build-up. It must always follow the manufacturer’s instructions to ensure proper curing, stability, and long-term performance.
Should Existing Flooring Be Removed Before Floor Levelling?
In most cases, yes — your existing flooring should be removed before any floor levelling work begins. Removing the old surface allows the levelling compound to bond directly to the subfloor, ensuring proper adhesion, structural stability, and a long-lasting result.
Certain floor coverings can trap moisture, move over time, or prevent primers and levelling products from bonding correctly. By exposing the bare subfloor, we can identify any damage, uneven areas, or concrete issues that need to be addressed before the levelling process starts.
This step is essential for achieving a perfectly smooth, durable surface that will support your new flooring for years to come.
