Frequently Asked Question with Real Solutions
Nupave’s Concrete Help Centre is an ongoing project that will continue to grow as we encounter new problems, solutions and real-world concrete issues across Melbourne. Our intent is to not only explain the issue and how to rectify it but to show you and give you a guide you can work from and gain an understanding. This page was created to help people make informed decisions, better understand concrete problems and learn practical ways issues may be repaired or prevented.
Concrete Repair
Concrete damage can occur for many reasons including ground movement, moisture penetration, heavy vehicle traffic, poor drainage, ageing concrete and steel reinforcement corrosion. At Nupave, we provide a range of concrete repair solutions designed to improve both the appearance and condition of damaged concrete surfaces across Melbourne.
Our concrete repair services include crack repairs, cross stitching, spalling repairs, concrete cancer treatment, washout repairs, edge repairs, surface patching and restoration of worn or deteriorated decorative concrete finishes. We also repair damaged control joints, trip hazards and areas affected by surface breakdown or moisture-related deterioration.
Where possible, we aim to restore and preserve existing concrete rather than recommend unnecessary replacement. Every repair is assessed individually, as different types of concrete damage require different repair methods depending on the cause, severity and future movement potential of the slab.
From residential driveways and pathways through to commercial concrete repairs and ongoing maintenance programs, Nupave provides practical repair solutions focused on presentation, longevity and preventative maintenance.
How Should you Repair Concrete Cracks?
Concrete Crack Repair
Concrete cracks can occur from ground movement, shrinkage, tree roots, moisture changes, heavy vehicle traffic or slab settlement over time. In this concrete crack repair article, we explain the different types of concrete cracking, what causes them, and when cosmetic repairs may be suitable versus when more structural repair methods may be required.
We also cover repair techniques including crack chasing, cross stitching and movement-related repairs used on driveways, pathways and decorative concrete surfaces. Understanding why concrete cracks is important in selecting the right repair method and helping reduce the risk of future deterioration or recurring movement.
Can Concrete Damaged by Rain During Pour be Fixed?
Concrete Damaged by Rain During Pour
Rain can seriously affect freshly poured concrete if the surface has not had enough time to properly set. In this article, we explain how concrete damaged by rain during pour can lead to surface weakening, dusting, scaling, washouts, uneven curing and long-term durability issues if not addressed correctly.
We also cover the signs of rain-damaged concrete, when repairs may be possible, and when replacement may be the better long-term option. From light surface marking through to severe washout and weakened concrete finishes, understanding the extent of the damage early is critical in preventing future deterioration.
What is Concrete Cancer and Spalling?
Concrete cancer and spalling are both signs of concrete deterioration. Spalling is when the surface flakes, chips or breaks away, often from moisture, poor concrete, impact or corrosion underneath. Concrete cancer is more serious and usually happens when steel reinforcement inside the concrete rusts, expands and forces the surrounding concrete to crack or break apart.
Not all spalling means concrete cancer, but both should be inspected properly before resurfacing, coating or sealing. If the underlying cause is ignored, the repair can fail again.

Concrete Resurfacing
Concrete resurfacing is a cost-effective alternative to removing and replacing existing concrete. In this section of our Concrete Help Centre, we cover what concrete resurfacing is, how resurfacing systems work, typical pricing considerations and the different decorative finishes available including stencil, slate, exposed aggregate resurfacing.
We also explain common resurfacing problems such as delamination, whitening, sealer failure, moisture-related issues and premature wear, along with the factors that can cause them including poor preparation, incorrect sealing methods and underlying slab movement. Understanding both the benefits and limitations of concrete resurfacing is important in selecting the right system and maintaining long-term performance.
What Is Concrete Resurfacing?
What Is Concrete Resurfacing?
Concrete resurfacing is the process of applying a new decorative coating system over existing sound concrete to improve its appearance, texture and durability without the cost and disruption of full replacement. In this article, we explain what concrete resurfacing is, how resurfacing systems bond to existing concrete and the different finishes available including stencil concrete, slate impression, exposed aggregate resurfacing and colour sealing systems.
We also cover where concrete resurfacing can be used, what preparation is required, common misconceptions about resurfacing and the factors that determine whether an existing concrete slab is suitable for resurfacing or may require repairs first.
How much Does Concrete Resurfacing Cost?
Concrete Resurfacing Cost Melbourne
Concrete resurfacing costs in Melbourne can vary depending on the size of the area, condition of the existing concrete, preparation required and the decorative finish selected. In this article, we explain the main factors that influence concrete resurfacing pricing including crack repairs, grinding, surface levelling, sealing systems and the type of resurfacing finish being applied.
We also cover the differences in cost between stencil concrete, slate impression, spray paving, exposed aggregate resurfacing and colour sealing systems, along with the long-term value resurfacing can provide compared to removing and replacing existing concrete. Understanding what affects pricing is important when comparing resurfacing quotes and selecting the right system for your project and budget.
Concrete Hazards
Concrete hazards can develop gradually over time and are often overlooked until they become a safety risk, trip hazard or costly repair issue. In this section of our Concrete Help Centre, we cover common concrete safety and surface problems including slippery concrete, steep driveways, trip hazards, lifting slabs, poor drainage, worn textures, algae build-up and deteriorating concrete surfaces.
We also explain how incorrect sealing methods, moisture, surface wear and ageing concrete can contribute to dangerous conditions on residential and commercial properties. Understanding the causes of concrete hazards is important in helping reduce slip risks, improve safety and maintain the long-term condition and usability of concrete surfaces.
How Do You Make a Steep Driveway Safer?
Steep Driveways
Steep driveways can become dangerous when concrete surfaces lose texture, moisture builds up or incorrect sealing methods create slippery conditions. In this article, we explain the common causes of slippery steep driveways, why some decorative concrete finishes become hazardous over time and the different methods used to improve traction and surface grip.
We also cover slip-resistant sealing systems, textured resurfacing finishes, drainage considerations and maintenance methods that can help reduce slip risks on steep driveways and sloped concrete surfaces. Understanding how surface texture, sealer choice and ongoing maintenance affect traction is important in creating a safer and more durable driveway surface.
Why Does Concrete Become Slippery?
Slippery Concrete
Concrete can become slippery for many reasons including worn surface texture, algae and mould growth, incorrect sealing methods, moisture exposure and general surface wear over time. In this article, we explain the common causes of slippery concrete on driveways, pathways, pool surrounds and commercial surfaces, along with why some sealed concrete surfaces become more hazardous when wet.
We also cover different methods used to improve traction including slip-resistant sealers, textured resurfacing systems, cleaning and maintenance programs, and surface preparation techniques designed to increase grip without completely changing the appearance of the concrete. Understanding why concrete becomes slippery is important in helping reduce slip hazards and maintaining a safer surface long-term.
What should I do with my concrete?
The right option depends on the condition of the concrete, not just the finish you want. If the slab is structurally sound but looks worn, faded, stained, slippery or outdated, a coating or resurfacing system may be the most practical way to improve the surface without removing the concrete. This can include spray-on resurfacing, stencil finishes, exposed aggregate-style resurfacing, sealing or other decorative coating applications. If the concrete has major cracking, movement, sinking, severe spalling, drainage problems or failed base preparation, replacement may be the better long-term option. The best approach is to compare the existing slab condition, repair requirements, expected lifespan, cost, disruption and maintenance before deciding between resurfacing, sealing, coating or new concrete.

Concrete resurfacing vs new concrete
Choosing between concrete resurfacing and new concrete depends on the condition of the existing slab, the amount of cracking or movement, drainage, budget, access, desired finish and long-term expectations. Resurfacing is often suitable when the concrete is structurally sound but worn, faded, stained or slippery. New concrete is usually the better option when the slab is badly cracked, sinking, moving or structurally failing. Read our full concrete resurfacing vs new concrete comparison to understand the cost, lifespan, disruption and suitability of each option.
