Property maintenance and remediation specialists can safeguard buildings and residents as a shortage of skilled tradespeople creates challenges for strata managers.

A perfect storm of low interest rates and government housing incentives during COVID 19 has fuelled a construction boom in Sydney that has also had another side-effect – a critical shortage of tradespeople.

The scenario is a headache for strata managers responsible for property repairs, with the Housing Industry Association (HIA) predicting that the nationwide shortfall of skilled tradies such as plumbers, bricklayers, electricians and builders could last for at least two more years.

The HIA Trades Availability Index deteriorated in the September 2021 quarter, indicating that the building industry is experiencing the most significant skills shortage since the inception of the report almost 20 years ago. The index declined from -0.53 to -0.69 for the quarter, with any number below zero indicating a skills dearth.

Sydney has been one of the hardest-hit cities, with COVID-19 and the highly infectious Omicron variant adding to the crisis. This has left many strata managers struggling to get urgent work done on buildings, leading to complaints from residents and potential legal liabilities if properties are unsafe.

Issues such as concrete cancer, cracked driveways, unsound balconies and the general deterioration of buildings should be addressed quickly and professionally.

Engage a trusted remedial builder 

The tradie woes have underlined the value of calling on the services of an experienced remedial building maintenance contractor that can work on commercial and multi-residential properties.

These service providers pride themselves on quickly mobilising their teams of tradespeople and getting problems assessed and repaired. Drawing on their network of tradies, they can ensure that any work is completed as efficiently as possible. This minimises the financial and legal risks associated with building project delays.

While remedial building contractors are an ideal solution for strata managers, it is important to choose an appropriate and experienced provider. Ideally, any contractor should be ISO-certified and hold accreditation with relevant industry bodies such as ACRA, an association which is committed to assisting the advance of concrete repair, remedial waterproofing, remedial building and other associated activities.

Although individual tradies may be able to take on some building repairs, it is important to get remediation specialists to check issues that may be the result of long-term structural problems with a building or its surrounds.

Benefit from a one-stop-shop service 

One of the biggest issues for strata managers is dealing with multiple trades when significant building repair work is needed. For example, if plumber and electrician schedules are not aligned, it can delay projects.

However, remediation specialists can coordinate the work, which in turn can make a real difference to the timing and cost of a job. Such management oversight also limits disruptions for tenants and residents. In this sense, a trusted remediation expert can act as a one-stop shop and take full accountability for projects.

As the tradie shortage drags on, the temptation for some strata managers will be to call in any tradie who can, hopefully, get the job done. This is risky. Awarding projects, no matter how large or small, to workers without the appropriate qualifications or accreditations heightens the risk of safety and quality failures, which can ultimately have a negative impact on any work and budgets.

So don’t take chances – act quickly and always insist on remediation service providers with a proven track record.

Getting tradies for urgent building repairs during Sydney’s construction boom can be a nightmare for strata managers. So schedule a call to have your building repair needs identified and fixed by an experienced team.

An experienced remedial building company can make life a whole lot easier for strata managers.

All too often, strata managers face issues with the buildings under their watch as a result of defects caused by poor construction, weather exposure and general wear and tear.

Whether it is responding to signs of concrete cancer, addressing a cracked driveway, or organising balcony repairs, it is important to get these problems and others fixed quickly and professionally. The positive news is that such repair and maintenance work need not be so stressful if strata managers take the following advice.

Get remediation specialists to do the work

While individual tradespeople and handymen may be able to take on some repairs, it is important to get remediation specialists to address issues that may be the result of long-term structural problems with a building or its surrounds.

These experts are accustomed to working with strata managers who look after commercial and multi-residential properties. They also know how important it is to respond quickly and reliably to building problems and to get the job done right the first time.

Insist on a project plan

Experienced remediation experts appreciate the importance of liaising honestly with strata managers and delivering on their promises. Up front, they should be able to provide you with a clear plan to identify the problem, outline the repair work that is needed, and estimate the likely timeframe for the job, or accordingly work with your consultant or engineer to do this. This will give you a solution that is on time, and on budget.

Put a premium on communication

Another advantage of dealing with remediation specialists, rather than individual tradies or smaller building businesses, is that they are experienced in communicating with all stakeholders who are involved in a remedial project. They will advise owners and residents about works that are planned, and alert them to any disruptions they are likely to experience.. They can also co-ordinate any traffic-management systems that may be required, and arrange for sign-off with building owners or managers.

Understand the importance of coordination

One of the biggest bugbears of strata managers is dealing with multiple trades when significant building repair work is needed. The plumbers may not turn up on time, or the electricians may not be available when the builders need them.

However, remediation specialists can call on their trusted network of tradespeople to coordinate the work, which in turn can make a real difference to the length and cost of the project. Such management also limits disruptions to tenants and residents.

Play it safe

Completing works in a safe environment is the number one priority for all stakeholders, without exception. As a bare minimum, a remediation specialist should complete a risk assessment prior to works commencing to ensure the safety of all parties involved. Preferably, the contractor should be ISO certified to raise the bar further and hold accreditation with relevant industry bodies such as ACRA.

Awarding projects, no matter how large or small, to organisations without any of the above accreditation introduces the risk of failure with regard to safety and quality – which can ultimately have an impact on the budget and program.

 The bottom line is that strata management is difficult and stressful enough without having to deal with building repair dramas. So, to relieve any headaches, make sure you contact a respected remediation specialist who has a proven track record in the industry.

Unacceptable or poor-quality repairs are a problem that strata managers can do without. So schedule a call to have your building repair needs identified and fixed.

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 may start to appear. 

Many factors can contribute to these defects. The causes can be as varied as design loopholes, overloading and also structural deficiencies. Environmental factors and natural hazards can also 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 embedded in the concrete begins to rust due to the presence of moisture. As the steel reinforcement corrodes, it expands. As a result, the surrounding concrete damages and starts cracking. This allows more moisture to penetrate the concrete and further corrode the steel reinforcement.

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: 

Some of the more obvious signs of concrete cancer are:

  • Cracking/flaking of concrete.
  • Rust staining on the outer surface of concrete.
  • Drummy or loose render. 

Causes of Concrete Cancer:

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

Some of the common ones are:

  • Poorly prepared and placed concrete during construction. This can allow moisture into the concrete inducing concrete cancer. 
  • Incorrect spacing and placement of the steel reinforcement during the construction process.
  • Insufficient concrete coverage over the steel reinforcement.
  • Stress fractures or surface degradation over time can result in water penetration into the concrete and provide a perfect environment for corrosion. This later causes concrete cancer.

4 Signs your Building has Concrete Cancer


The remediation bill can be startling if a building gets concrete cancer. So it pays to be able to identify the early indications of trouble.

Early diagnosis of a disease can minimise its potentially catastrophic effects.

The same is true of concrete cancer, an insidious condition that lurks beneath the surface and causes a building to become ‘sick’. Also known as concrete spalling, the causes of this problem are well known.

Steel and iron bars are used to reinforce the concrete in buildings and, if proper construction processes are followed, there is usually nothing to worry about. However, if this steel is exposed to air and water through cracks and leaks, a carbonic acid can form, causing the bars to corrode. Once this process starts, the steel keeps expanding and the concrete progressively deteriorates. Without remedial action, the issue will only get worse and the building’s structural integrity can be compromised.

For confirmation that your building is suffering from concrete cancer, the services of an engineer or specialist concrete repairer will be required. Nevertheless, there are some external visible signs that should raise red flags. 

  • Cracking and flaking

Unfortunately, it can take many years for concrete cancer to become obvious to the untrained eye, and by then the damage to a building may be extensive. Cracks in the concrete of soffits, beams and columns are an early sign of potential problems. So, if such cracks appear, no time should be wasted in getting a proper inspection by a concrete spalling repair company. A relatively small amount of money spent on the problem now can avert significant future repair bills.

  • Rust stains

Reddish or brown stains on the surface of concrete are a clear sign of deterioration underneath. If the steel reinforcements are exposed to air, it can create iron oxide, or rust, that looks as though it is bleeding from the concrete. Steel reinforcing materials need to have been properly treated before being incorporated into a slab. In cases of concrete cancer, the steel can expand many times its normal diameter inside the concrete, leading inevitably to cracking and crumbling.

  • Bubbling

Bubbling, or plating, of concrete render or paint is also an indication of concrete cancer. Inadequate water-proofing is often to blame.

  • Moisture and leaks

If you see evidence of leaks in internal walls or overhead concrete surfaces, initiate an inspection. Rising moisture coming through cracks in the concrete may be a consequence of poor workmanship or inferior waterproofing materials.  You may also see a white, crystal-like substance that looks similar to salt. Concrete in coastal areas is more vulnerable to concrete cancer because of the higher salt content in the air, which can also speed up rusting. Area with humid climates or high rainfall are more susceptible, too.


Any of the above symptoms may be an indication that your building has concrete cancer. If you spot them, call a concrete repairer immediately to have the condition properly diagnosed and, if necessary, treated. The only conclusive way to distinguish between concrete cancer and something less worrying is to get a professional opinion.

Whatever you do if you see possible signs of concrete cancer, do not ignore the issue. Leaving the cancer to spread will only add to the building’s problems – and the cost of repairs – over the long-term.

If it is not treated early and definitively, concrete cancer can be an expensive headache for building owners. So click here to contact Sydney’s leading remedial building contractor to have your building diagnosed and repaired.


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.

For this purpose, you can trust an amazing concrete repair service in Sydney named Brookvale Industrial Maintenance. Here at BIM, we have certified master builders and trained individuals who will look after your concrete cracks. So if you have a concrete situation, just give us a call at (02) 9938 1740.

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.
