When it comes to concrete repair, it’s important to be proactive and address any issues as soon as possible. Ignoring potential problems can lead to much more extensive, and expensive, damage down the road. But how can you tell if your concrete needs repairs? Here are some warning signs to watch out for.

Structural Cracks
These are the most obvious signs that something has gone wrong. River City residents always call concrete repairs in Brisbane as soon as they notice these cracks because they know structural cracks can cause structural failure. They should never be ignored and should always be addressed immediately.
Structural cracks typically occur due to structural instability or movement in the foundation. This can be caused by soil movement, water saturation, drainage issues, or other factors that put additional strain on the building structure. It is important to identify structural cracks quickly and repair them before further structural damage can occur
These issues often appear in the form of horizontal or vertical lines on walls, ceilings, and floors. They may also appear at the corners of doors or windows and around structural supports such as columns and beams.
Spalling
Spalling concrete means that the surface of the concrete is breaking away and flaking off due to weathering, water damage, or freeze/thaw cycles. It’s a warning sign that your concrete needs to be repaired as soon as possible. Spalling can occur on any exposed surfaces like driveways, sidewalks, patios, steps, and foundations.
It must not be ignored because it can lead to more serious damages such as cracks in the concrete and even structural failure if left unchecked for too long. Repairing spalled areas correctly requires removing all spalled material up to 2 inches deep or deeper (depending on the severity), then filling in with new concrete and finishing with an appropriate sealer. In some cases, spalling can also require additional repairs if the underlying structure has been affected.

Uneven Surfaces
When you feel like the surface you’re working on is uneven, you should determine what caused it. Here are the options:
- Poor installation
- Poor curing of the concrete
- Freeze/thaw cycles
- Chemical attack from deicing salts, oils, or other contaminants
- Heavy traffic or heavy loads
Uneven surfaces are a concrete repair warning sign that must not be ignored. This could indicate a more serious problem with the foundation or condition of the concrete. Address them as soon as possible in order to avoid further structural damage. Repairing uneven surfaces is often easier and more economical than replacing entire slabs.
Common repair techniques include mud jacking, slab jacking, epoxy injections, grinding and leveling, and polymeric sanding. Depending on the severity of uneven surfaces and the repairs needed, professional concrete contractors can provide the best solutions. If uneven surfaces are not addressed, they may result in uneven walking surfaces, trip hazards, pooling water, drainage issues, and uneven slabs.
Staining
Concrete is a great design option, even for indoor use, but once you notice stains on your concrete, it’s time to pay attention. Staining on concrete is a sign that the integrity of your floor is being compromised, and if ignored can lead to costly repairs in the future.
Staining happens when water or oil penetrates through cracks in the concrete and begins to break down the surface layer. This staining can be caused by excessive water usage, inadequate sealants due to poor installation, or even faulty equipment used during the installation process.

Discoloration
Concrete may start losing its color due to discoloration. This discoloration can be an indication of a number of problems, such as inadequate curing, water exposure, and chemical exposure. If discoloration is noticed on concrete surfaces, it should be addressed immediately. Ignoring discoloration can lead to further deterioration and costly repairs down the line.
Discoloration often appears in patches on the surface or throughout the slab. It is usually visible as fading colors or spots of discolored material that do not appear to match with surrounding areas. In some cases, discolored areas may also contain powdery deposits, indicating damage to the underlying concrete layer.
Pitting
Pitting occurs when a chemical or physical reaction causes the surface of the concrete to become irregular and form small pits. It is important to repair pitting quickly, as it can cause significant damage to concrete structures if left unchecked. Pitting is a warning sign that a more serious problem may be developing, such as corrosion or structural weakness. Without prompt attention, pitting can lead to further deterioration and costly repairs in the future.
There are a few ways to tell if pitting is occurring on your concrete structure: you may notice small indentations on the surface, or you could find evidence of cracks developing. If any pitting is found, it’s important that you take action straight away. Although the process itself isn’t always dangerous, the underlying issue causing it needs to be identified and rectified.

Efflorescence
This issue is common in concrete and occurs when the salts from water seep through the surface of the concrete and it evaporates. It leaves behind a white powdery substance that is not only unsightly but also dangerous for your concrete.
To remove efflorescence, address the source of moisture first. This can be done by sealing or waterproofing the concrete to prevent future efflorescence from developing. Additionally, you can use a special efflorescence cleaner to remove the powdery substance from your concrete and keep it looking great for years to come.
Drainage Issues
Concrete issues can further cause drainage problems, as drainage issues and water drainage is necessary for the concrete to remain in good condition. Poor drainage of water can lead to a variety of problems, including puddles on the surface, cracks or fissures, scaling, spalling, and more. If drainage issues are already present around your property and are left unchecked, they can quickly worsen, leading to expensive repairs down the line.
The best way to tackle drainage issues before they become an issue is by installing drainage systems and pumps that help divert any standing water away from structures. Additionally, proper grading should be done around structures in order to ensure proper drainage.
Issues with concrete should never be taken lightly because they can further evolve into bigger issues you may not be able to handle. All these different problems present warning signs of what could happen if you don’t react timely. Make sure to know what to do and call repair services if you don’t!
