Concrete Cancer—Symptoms, Causes & Treatment.

Concrete is one of the most robust and versatile construction materials. However, it is also predisposed to wear and tear. With usage and time, different types of defects start to appear in the concrete structures as well. 

Many factors introduce these defects. These causes vary from design loopholes to overloading and also structural deficiencies. Environmental factors and natural hazards cause concrete defects that need urgent concrete repair. 

But in today’s article, we will guide you through a common defect known as concrete cancer or concrete spalling. Let’s begin. 

What is Concrete Cancer? 

Concrete cancer is a defect that happens when the steel reinforcement in the structures begins to rust. When the steel reinforcements become corroded, expansion occurs. As a result, the surrounding concrete damages and starts cracking. 

The term concrete cancer is self-explanatory that these conditions spread rapidly. A reliable concrete repair contractor must examine and repair it. Because if delayed, it can significantly impact the building structures making concrete cancer repair more expensive and challenging. 

Symptoms of Concrete Cancer: 

Only a licensed concrete repair specialist can confirm if your building is suffering from concrete cancer. This is because sometimes you won’t even know that it is happening. However, some visible signs show cancer’s presence. 

Some of them are:

  • Any cracking/flaking of concrete. Concrete Spalling is generally an early stage of this defect. Therefore, always contact a concrete spalling repair company promptly to get it inspected and rectified. 

  • The rusting causes stains to appear on the outer surface of the concrete. If you see any rust stains, it best to consult a concrete repair company for an inspection.

  •  Concrete bubbling, i.e. when the render starts falling off and leaks, are some important symptoms which you should not ignore. 

Causes of Concrete Cancer:

A variety of factors causes concrete cancer, including malpractices in the construction process, and some involve unavoidable natural factors. 

Some of the common ones are:

  • When a construction company poorly prepares and pours the substrate, it allows water and moisture to pass through the cracks inducing concrete cancer. 

  • The reinforced steel plays a vital role in avoiding structural issues like concrete cancer. But the building contractor should prepare it well to avoid issues in future and maintain the structural integrity.

  • When reinforcement ends are closer to the surface, or incompatible metals are placed together, it allows water to enter the concrete, thus causing rusting steel reinforcements leading to spalling and concrete cancer.

  • Regular deterioration and stress fractures result in water seepage and provide a perfect environment for corrosion. This later causes concrete cancer.

Benefits Of Repairing Your Damaged Concrete

Concrete slabs are one of the most durable, elegant, and affordable house floors. They are attractive and classy under heavy usage. However, concrete cracks can detract from the attractiveness of concrete floors.

These cracks become scars on your concrete floors which then should be repaired on time. But, people don’t tend to take interest in repairing concrete floors, even though concrete repair is essential in enhancing its beauty and durability. 

There are several environmental factors that contribute to cracking. However, on-time concrete spalling repair brings many benefits to you and lessens the risks associated with concrete damage. Some of the concrete repair benefits are mentioned below. 

Let’s check them out.

Prevents More Damages

A small area of concrete that is in great condition prevents further damage but if it gets weaker or cracked, it will start to break into pieces. Let’s take an example, a small crack in concrete floors provides a route for the water to flow into the concrete. The concrete can then absorb the water easily, making the cracks bigger. 

In winter water can also freeze inside the concrete which causes it to expand which can result in further damage. These problems clearly teach us that procrastination in concrete repair will lead to larger, more expensive repairs over time. 

Risks Of Injury

Large cracks or damage on concrete floors becomes dangerous because it can cause many accidental injuries. So it should get fixed urgently to avoid this issue. 

If you are a healthy individual, it might be easy for you to escape the damaged concrete areas. But it is difficult for the elderly who already suffer from medical problems like knee pain and high blood pressure, which can lead to poor balance.

Above all, situations like these can lead to severe injuries. So it’s best to be proactive with your concrete repair in order to avoid them.

Attractive Appearance

No matter how small the cracks are on the surface, the concrete will become less appealing to the eye. This isn’t something you want if you’re trying to make a good impression on your customers. 

People find it more comfortable to buy things from shops where they don’t have to trip over the concrete to reach the store. These things can play a major role in the success of your business, so consider fixing damaged areas. 

Saves Money

Concrete repair is usually cheaper than other alternatives. Never procrastinate over the damage for too long. If you do so, you will also need to repair or replace the whole structure because the cracked concrete or damage will no longer be fixable. And this is naturally more expensive than repairing the damage in the beginning. 

Further, it consumes more time, money, and can cause disruption in the area. So busy owners should make repairs a priority in order to avoid large-scale repairs that could cause a store closure.

Bottom Line

Cracks on concrete may indicate some important structural problems. So it’s crucial to fix concrete spalling or cracked concrete areas on time before it becomes dangerous to others. 

However, it is important to use reputable and professional concrete repair companies to repair your concrete cracks.

Five Reasons Why Your Home Needs Concrete Repair

For outdoor spaces, concrete finishing is excellent. It is a common choice in many parts of Sydney. We have been helping hundreds of clients enjoy perfect concrete finishing, and if there are problems, we carry out comprehensive concrete repairs.

But, there have been questions about the reasons why concrete finishing gets damaged quickly. The truth is direct; if it is done well, you will enjoy your concrete finishing for a long time, but a shoddy job will lead to quick deterioration.

However, there is good news. Our team can resolve many of the problems encountered with concrete finishing.

Why is Concrete the Common Choice for Finishing in Australia?

We can name a hundred and one reasons why people choose concrete. But, the top reasons are as follows;


Concrete finishing is durable. Our clients confirm that they do not need to replace their concrete finishing surface for a long time. This means they get more value for their investment in the project.

It is Beautiful

Concrete finishing also improves the appearance of the outdoor space where it is done. The beauty of concrete finishing is more apparent when the space is complemented with nice-looking plants that act as borders around the concrete-covered patch.

Weight Support

Many people also prefer concrete finishing because it can support the weight of cars and other vehicles. However, concrete can collapse under the excessive weight if there are problems with the finishing. 

It is Easy to Clean

Cleaning and general maintenance of concrete finishing is not a problem for many homeowners. This means less stress, in addition to other benefits.

Why Concrete Gets Damaged Quickly

To get the best results, only experienced contractors should be hired to do the job. Here are the common reasons why concrete damages occur often;

Poor Quality Concrete Mix

Concrete cancer happens when the quality of concrete used for the job is below the right standard. The problem is evident when wear and tear become visible on the concrete surface. The solution is to perform a concrete cancer repair immediately to prevent further damage.

Inadequate Waterproofing Requires Concrete Repairs

Another cause of concrete damage is exposure to moisture or chemicals. This is caused by faults in the waterproofing job done while laying the concrete surface.

This problem is also solved by a professional approach to restoring the waterproofing and plugging the sources of water leaks that introduce moisture beneath the concrete.

Faulty Building Structure

Defects in the building could also cause damages to the concrete finishing. If this is the case, you should organise concrete repairs as soon as you can to prevent further structural damage. However, it is a job for only experienced contractors. That’s why our concrete repair service in Sydney is the best solution for this problem. 

Concrete Spalling Due to Poorly Reinforced Concrete

Concrete spalling happens when chips of concrete start falling off the finished surface. The absorption of water also causes it during winter, which becomes frozen in the concrete in lower temperatures. The solution is proper concrete spalling repair. The entire area affected by spalling can be fixed.

Exposure to Extreme Heat

Concrete finishing in areas prone to extreme heat can also cause damages. If this happens, reinforcement can prevent further deterioration. However, excessive heat causes spalling, and cracks can appear on the concrete surface.

The best way to handle concrete damages is to act fast. Give us a call if you observe signs of wear and tear on your concrete, and we will respond quickly to carry out proper concrete repairs.

Have you assessed a visible piece of cracked concrete and are unsure of the severity? Have you observed other materials in your dwelling have also cracked? Are you asking yourself if it’s time you started looked at a concrete repair? Here are some tell tale signs that you need concrete repairs. The most common sign you may be in need of concrete repair is if you observe cracks appearing in the concrete. Although on face value it might seem only superficial however there is risk that the cracks could be caused by soil expanding and contracting from exterior elements. If you begin to notice surfaces aren’t level or are uneven such as the concrete itself, exposed beams or walls, this may be as a result of weather conditions or potentially the work of sub-standard foundation. In the event you prolong having a professional inspection of the damage, you can run risks of the infected area crumbling and breaking which could ultimately lead to structural instability and potentially injury. The final tell-tale sign of the need for concrete repair is obvious signs of aging. Consistent with other building materials, concrete will experience wear and age over its life. The signs mentioned above are only some signs that your concrete is worn due to age or other factors. Compromised concrete will often present shabby and worn. If you have observed any of the above, it’s a good time to engage a concrete repair specialist.

Why Get Concrete Cancer Repairs Done

Concrete cancer can possess a major threat to the structural integrity of buildings and the following provides some insight into what actually is concrete cancer and more importantly, why you should seek to immediately arrange concrete repairs to the infected concrete that has been compromised. In a typical concrete building, reinforced steel bars or mesh are used during the construction process. Over time or as a result of poor craftsmanship, the steel can be exposed to air and water leading to formation of a weak carbonic acid causing steel to corrode. As corrosion occurs, steel is typically forced to expand leading to cracks in surrounding concrete. The definition of concrete cancer is used when cracks in the concrete allow for the steel to be exposed to surrounding elements that will ultimately act a catalyst to steel corrosion. As a result of the corrosion, you will find the building’s structure can become compromised and a potentially devastating hazard can emerge. Now that the gravity of concrete cancer has been established we can further discuss why concrete cancer should have a concrete repair carried out. If the concrete cancer is left untreated you’re essentially leaving a ticking time bomb or playing roulette as to how long the structure will hold up before potentially beginning to crumble further or collapsing all together. This is why you should call a professional and have a concrete repair carried out on the structure or impacted area.

Prevention of Concrete Cancer

If the devastation of the impact of concrete cancer has you concerned, you are likely seeking to understand what preventative measures can be taken to avoid a potentially costly concrete repair. Initially it’s advised to avoid the instance of concrete cancer from the beginning, however this may not be feasible in some cases if there’s unknown issues with the concrete. Therefore, early detection and repairing the impacted concrete is key if it has occurred. The best preventative measure is waterproofing to guard the building from concrete cancer. High quality Wolfin or Cosmofin waterproofing membranes offer extreme resistance to tears and punctures in turn minimising water leakage into the structure. This coupled with the exceptional elongation properties prevent leakage condition from building movement. These waterproofing membranes boast exceptional resistance to extreme weather conditions and could allow you to avoid a potentially costly concrete repair.
