Boosting the Value of Apartment and Office Buildings with Facade Upgrades | Remedial Building Services

We may be taught to never judge a book by its cove [...]

BOOSTING THE VALUE OF APARTMENT AND OFFICE BUILDINGS WITH FAÇADE UPGRADES


We may be taught to never judge a book by its cover, but in real life, most people will form opinions about a person in just seconds. A building is no different, and first impressions count. When people are looking for an apartment to live in or an office space to buy or rent, they will look for buildings with attractive, safe-looking modern facades first. For obvious reasons really - who would want to live or work in a building with cracks on the external walls or worry about the risk of falling cement. Similarly, buildings with leaking windows or  where the façade is reminiscent of the 60s are not things people generally see as positive.


The importance of Façade Upgrades

For building owners the requirement is clear -  a Façade Upgrade can help boost the value of your building, which it turn enables you to command a higher level of rent or sales price. Of course, a facade upgrade does require an upfront cash outlay, but ultimately, when you consider that you may get a higher sale price, can offset the cost as an expenditure or even address a significant problem before it gets to be more expensive, in the end, they can be relatively affordable.. Additionally, a well time Façade upgrade gives you the chance to reinforce the structural integrity of the building or fix whatever structural damage may be present.

The risks of a poorly maintained façade

It doesn’t matter what the paper says. Even if you have a genuine certification from an experienced engineer that says your building is structurally sound, people can be superficial. They can be paranoid that a huge crack on the facade or put off by a handrail that is rusting, thinking that this is just a sign that the building has not been looked after properly. In short, people wouldn't be risking their lives and investments for things they "think" are not worth their money.

What is typical in a Façade Upgrade

There are a lot of different components that go in to a façade upgrade, but typically they can include:

  • Structural upgrades
  • Concrete repair
  • Brick tie installation
  • Membrane replacements
  • Architectural coatings
  • Balustrade and Balcony upgrades
  • Window replacement
  • Façade painting
  • Engineered and architectural designed alterations

Structural Repairs as Part of Upgrades

Yes you can apply a ‘coat of paint’ and for the short-term it looks good, but to ensure long-term health and safety and to lower ongoing costs and extend the value of your investments, you need to deal with the main cause of the problem. The cracks on the walls may be caused by concrete cancer causing the concrete and bricks around them to become displaced.

At Remedial, we can work with you to assess the needs of your building and provide a range of practical, feasible solutions to ensure that you obtain great value on your facade renovation. Learn more about the process when you contact us for a no-obligation appointment today.

A Guide to Appointing the right Structural Repair Specialist | Remedial Building Services

With more than 40 years experience in structural r [...]

A GUIDE TO APPOINTING THE RIGHT STRUCTURAL REPAIR SPECIALIST


Whether you own or manage a residential or commercial property, routine buildings inspections should be something you factor into your maintenance plans. Whether it is to ensure compliance with building or fire codes, or as part of a good maintenance schedule, property inspections help to keep you abreast of the health of your building. Done properly, they ensure your property is compliant; detect potential structural problems before they become larger (and significantly costlier); as well protecting the value of your asset into the long-term.
 
Structural problems and thus structural repairs are different to renovations or non-structural repairs. The need for structural repairs can vary, but the range of services usually required included a range of issues from concrete cancer, to balustrade replacement upgrades, through to carbon fibre strengthening, brick growth and waterproofing.
 
In the situation that you do need to hire a structural repair specialist, it is important that you find the right one, but knowing what to look for – for something you have little experience with – in a contractor can be somewhat overwhelming. To help make life that little bit easier, we have put together a cheat-sheet on hiring a structural repair specialist.

  • Research

The first thing you should do is some research. Understand to the best of your abilities what the issues affecting your property are, and if you can, identify not only what the larger more obvious issue is, but also smaller, seemingly unrelated ones as well.

  • Approach a third-party consultant

It may seem like an unnecessary expense, but for larger jobs, hiring a professional consultant such as a structural engineer, can save you time and money. These engineers have the experience to identify your issues and can be appointed to oversee the appointment of the right building repair contractor. Further, they have the expertise to ensure the applied solutions are adequate and cost effective for your particular circumstances.

  • Get a Written Report

Your chosen specialist should be able to inspect, analyse the damage and provide a written report which outlines the issues and the remediation techniques. This report should itemise all the defects, their approach to rectification, building materials and other pertinent facts.

  • Ask for Qualifications

Whether you use a consulting engineer or going direct, it is advisable that you ask for the necessary certifications that show they are qualified for the job. Case studies, testimonials, accreditations will prove that the expert has the authority to perform the necessary repair work.
Tenure within the industry in the area of structural repair (as opposed to say general building) is another strong indicator of expertise. A company like Remedial Building Services who have more than 40 years of experience as an industry leader, demonstrates that the team behind the company has working knowledge and experience on every scenario about building structure damages, whereas a company with 40 years’ experience in the construction of new homes, are not going to be able to help

  • Ask for a Proposal

After consultation, the structural repair expert should work on the numbers and provide you with an estimate of the building repair, a timeline for completion and their relevant insurances.

  • Hire the Structural Repair Specialist

Once you are confident with the supplier, ask them to draft a contract and get ready to begin.
 
Ultimately finding the right structural repair expert to look after your building is important in ensuring the safety of everyone in and around the building as well as protecting your significant investment. If you want to make sure you're getting reliable, long-term solutions for your building structures in Australia, ask us how we can help you.
 
We have over 40 years of experience in providing specialised building repairs for a variety of clients in Australia. With our considerable experience, we have also established a strong connection with structural and façade engineers who we can tap into for highly specialised situations when necessary.

Understanding Building Issue: Water Leaks | Remedial Building Services

We know that not everyone understands the building [...]

UNDERSTANDING THE IMPACT OF FAILED WATERPROOFING

A water leak is a nuisance, but sadly too many people think that is all it is. As often as not, when we are called in to assess the issue, we hear owners explain that they thought that as long as the leak is not causing damage to property within the building there is no great need to rush to fix it. Sadly, this is an expensive misperception. In fact, this is what water leaks could be doing to your property:

  • Leaking into the cavity causing mould
  • Leaking into the cavity and causing exposed metal elements to rust thus causing concrete cancer or brick growth. This in turn causes structural damage which accelerates the issue.
  • Masking the true area being damaged. Just because you see water droplets in one spot, it does not mean that the water is coming in straight above. Often the water has tracked along a beam before falling, meaning other spots could be even more damaged
  • Damaging paintwork, electricals, carpet and more

POTENTIAL CAUSES OF WATER LEAKS

Water leaks may appear to be small but as water can track down from almost anywhere else, identifying the issue can be somewhat harder. That said, there are a number of potential causes which could be the cause of the issue:

  • On flat roofs the membrane designed to act as a waterproof barrier has been damaged (installation of new equipment is often a cause), or due to age started to be less effective
  • The flashings on the roof are not turned up high enough. In the event of sudden rain or due to a blocked drain, the water rises above the flashings and down the wall.
  • Flashings around your window have been inadequately installed meaning when it rains the wind pushes it up and under the flashings and into the cavity. To add to the confusion, this could mean the water enters the building one or many floors below.
  • Your plumbing is damaged causing either a mains pipe or a waste water pipe to dispel water where it shouldn’t.
  • You have concrete cancer on a flat surface such as a balcony which is allowing water to ingress through the slab and into the cavity. This is then running down the internal walls of the building

Waterproofing issues: What to look for and what to do | Rectification Services | Remedial Building Services | Remedial Building Services

Don't let waterproofing issues become an issue for [...]

ISSUES CAUSED BY WATERPROOFING FAILURE AND WHAT YOU CAN DO


Since 1969, our team of experts have been providing inspection and rectification services across building remediation, inclusive of waterproofing and water damage services. What many people fail to realise is that structural issues often arise as a result of water ingress and waterproofing failure. 

Whilst waterproofing issues are almost to be expected in older buildings, we are undertaking an increasing amount of work in newer buildings where, during the initial building process the builders and/or their contractors have overlooked specific structural requirements (or taken shortcuts) that have caused ongoing issues. Across the greater Sydney area we are seeing issues with
  • Drainage and water run off leading to ponding and permanent immersion which can lead to water ingress through points of failure 
  • Poor flashing protocols leading to water ingress
  • Poorly treated re-bars leading to rusting and cracking
  • Plantabox failure 
  • Structural failure

How to identify waterproofing issues

To the untrained eye, a seemingly small issue could be masking a larger issue. That said, whilst the following list can be an indication of a larger issue, it is not always the case. What we can recommend is taking the time to investigate, or getting someone to come look for you.
Warning signs to look out for include:
  • Blistering or peeling paint
  • Bubbles in the paint that hold water 
  • Mould, mildew and vegetative growth
  • Rust Stains on the concrete facade
  • Efflorescence (the white drip stains that can be seen on the edge of balconies and stairs)
  • Cracked walls
  • Internal and rising damp

Areas to Monitor for Waterproofing Issues

Waterproofing failure can happen almost anywhere on a building - especially if construction processes were skipped or rushed. However, key areas to consistently have your building manager or strata committee check include the following. 

Roof’s/Top floor

If you are in an apartment or commercial building, flat roof surfaces bare the brunt of the bad weather. When you next have significant rainfall, access the roof to look for areas where the water is ponding, see if there are blocked drains and or identify areas where you can see water getting into spots it should not.
It is also worthwhile looking at internal areas underneath to see if there is a seepage issue through ceiling spaces.

Drains, Plumbing and Irrigation

Faulty plumbing such as leaky drains, water pipes or irrigation can be difficult to spot, that’s why regular checks need to be made. Look for blockages, drips or leaks, no matter how small and rectify the issue promptly.

Window and Door Seals

Windows and doors have seals which are designed to keep water out, and as such, need to be regularly checked to ensure they remain impervious to the elements, day in day out.
We recommend checking to make sure the seals aren’t cracked. If you find they are damaged in some way prompt attention is important to ensure there are no secondary issues which become apparent.

Take Charge

At the end of the day, your building needs regular attention. Regular checks of the building to ensure integrity is a good way to ensure you catch any waterproofing issues early. Doing so can end up saving you thousands of dollars - both in terms of damage and repair costs.

What Remedial Building Services offer | Planter Box Repair | Remedial Building Services

If you want to know why you need more than a handy [...]

PLANTER BOX REPLACEMENT

Too often it seems that out of sight, is out of mind when it comes to adequate planter-box waterproofing. Time and again we have seen poorly implemented or absent membranes, resulting in boxes which look fine at first glance but which eventually begin to cause serious issues.

While these boxes will function perfectly well in the beginning, over time the effects of heavy rains or overwatering will begin to cause water penetration. As planter boxes are commonly located either adjacent to, or above habitable areas, water ingress caused by a leaking planter box can result in serious issues. Remedial is experienced in rectifying this situation and will typically take the following steps:

  • Remove existing plants and soil and safely relocate them for the duration of the works
  • Remove any water systems which may be in place
  • Remove current waterproof lining (if applicable)
  • Thoroughly clean drains
  • Install a new waterproof membrane
  • Thoroughly test the integrity of the new membrane
  • Install filter fabric
  • Install drainage cell
  • Install corflute from edge to edge
  • Either reinstall plants or leave this for a horticulturalist as stipulated by the owner

Water ingress and ponding can cause structural iss [...]

As often as not, the obvious signs of concrete cancer, and other structural issues are the tip of the iceberg. What we often find upon investigation is that the issues are all too often caused by water ingress into the concrete slab where it reacts with the reinforcing steel.

Once the steel can be treated or removed and replaced, the slab needs to be protected to prevent the issue occurring again. This is where correct waterproofing technique is of paramount importance.

With extensive experience across residential, commercial and industrial properties, we are often regarded as one of the most knowledgeable and professional companies in the waterproofing field.

WATERPROOFING METHODOLOGY

Having identified the original issues, we will take the time to ensure they do not occur again. We will undertake extensive substrate investigation, analysis of flashings and other elements around the slab to determine what measures to take and the most effective and viable waterproofing system for the particular job at hand.

The waterproofing systems we offer include:

  • Liquid membranes
  • Torch on membranes
  • Loose layered sheet membranes
  • Hypalon bandages
  • Tanking membranes
  • "Negative waterproofing" through injection
  • Applied chemical solutions
  • Polyurethane sealants

No job is too demanding, nor too large. We have applied our water proof membranes to a number of large and complex jobs around Australia including the Department of Education Building and Reserve Bank of Australia.

DIY TIPS FOR YOUR FLOORING SURFACE


5 Tips for maintaining your flooring surface

Whether or not you see it this way, the truth is, the floor in your warehouse, or your delicatessen, or your cool room, lab or food preparation area is an asset to your business. The rationale for this statement is simple: IF your floor breaks down, is unsafe or unhygienic, then you will need to shut down to to bring the floor back to a working condition and ensure your floor complies with relevant legal and OHS requirements. Worse still, if you are forced to shut down till the floor is fixed, you start to experience loss of revenue and this is where your floor starts costing you big money.

As with all your investments, your floor requires a bit of TLC. We've put together a list of things you can do to ensure your floor's lifespan is extended as long as it can be before you need to consider new flooring options.

DIY Tips for Your Flooring Surface

Clean the floor regularly

If you have an expensive piece of machinery, or a company car, you will undertake to service it regularly to ensure it operates at its optimum for as long as possible. Failure to do that will mean break downs and increased bills to fix it.

The same goes for your floor. If you don't clean it, grit, acids, chemicals and other debris will build up and damage your surface making it either unsafe or unhygienic (and smelly more often than not) or both.  You will then be required to undertake wider repairs or replacement of the floor.

Our tip is to clean the floor regularly (you will know better than we will what that means based on the nature of your business). Make sure you don't use abrasive chemicals which were not recommended for cleaning. If you do, your floor will suffer.

Teach your staff what is acceptable and not acceptable on your floor

If your floor is a showroom then it is unlikely you will want pallet racking on the surface, and similarly, if your floor is in use in a kitchen you will not want a forklift in the kitchen. Make sure you and your staff all know what is acceptable and not acceptable on your floor. Don't put your floor under undue stress and it will thank you.

Conduct regular inspections of your floor

You check the oil in your car, you monitor the quality of the products you produce, so you should check the floor on which your business is literally built. If you identify the floor is dirty you can clean it, or if you see signs of damage you can address them before they become more widespread. Remember, prevention is better than a cure.

Don't DIY flooring fixes for specialised surfaces

It may seem appealing or even easy to repair a flooring issue you have identified during a check. However, failure to prepare the area correctly prior to implementing a solution can result in you causing more damage than you think.   

If you fail to clean the surface, or prepare it properly your 'fix' may trap bacteria and moisture below the surface, causing the surface to bubble and crack very quickly (not to mention become unhygienic). Similarly if you use the wrong preparation to fix the surface, then you will likely just be creating a band aid solution which needs fixing sooner than you could think possible.

If you use machinery, ensure that your surface is resilient to that type of traffic

Seems obvious, right? Sadly a lot of people don't stop to think about this. They have a beautiful vinyl floor but need to take delivery of a large pallet of materials. So they let the driver use the forklift to offload the materials. Sadly, the twisting and turning of the tyres will rip the vinyl up.

Tiles are similarly prone to damage under heavy traffic. Our advice, make sure you think about the surface prior to conducting what may seem to be routine procedures. If you need to use forklifts for example, an epoxy floor trowelled to the right thickness is going to be required. In the same way it's horses for courses, different industries and business require different flooring solutions.

Understanding Waterproofing Solutions | Remedial Building Services

Learn about liquid membranes, torch-on membranes, [...]
Water leakages are one of the most common issues for commercial and industrial buildings. While occasional droplets may seem harmless, the truth is, these drops could be an ominous sign of a larger underlying issues which will become worse over time as water might penetrate through the ceiling, walls, or worse — the entire foundation of the building.
Ignoring these issues will pose long-term complications that will ultimately affect the overall structural integrity of the building. It is therefore vital to work on your building's waterproofing as an integral part of preserving its condition. Fixing it is a requirement, but which option should you consider? The waterproofing solutions that you can apply to your residential, commercial or industrial property are many and varied, so we've broken them down for you. 
 

LIQUID MEMBRANES

What are they?
This is a fully bonded waterproofing system that uses liquid film such as acrylics, polyurethanes, and bituminous emulsion (or asphalt), which cures directly right after it bonds to the surface being applied to.
Because of its liquid nature, it can easily take any shape or contour and can easily be applied in one piece. Best of all, it becomes almost integrated into the original structure, unlike other materials that are usually applied in sheets and are visibly a different part of the structure.
It is popular for its highly elastic properties, with an elongation range between 280% and up to 500%. Basically, this means it is highly effective for use in situations where buildling movement is expected with little to no damage at all. With this durability and flexibility, as well as its chemical and abrasion resistance and UV absorption, liquid membranes are a brilliant waterproof option.
What is it for?
As mentioned, liquid membranes are highly flexible, so it is ideal for complex pillars and wall designs as well as for corrugated roofing. Being low maintenance and extraordinarily heavy duty, it is perfect for high-traffic, busy areas such as factories, production floors, and bunding. 
 

TORCH-ON MEMBRANES

What is it?
Torch-on membranes are made from a mixture of bitumen or hydrocarbon and various polymers, usually Atactic Poly Propylene (APP) or Styrene Butadiene Styrene (SBS). They are self-adhesive, however, to reinforce their adhesive property, it is further blended with oils and resins.
Torch-on membranes are a sheet membrane system, meaning the solution is applied in large sheets. To be effective, each of the strips overlaps to it's neighbour.
Application is via one of two methods.  In an APP-mixed membrane, once heated with a butane torch, it starts to soften to expose a shiny bitumen surface that adheres to the substrate. The SBS, rubber-modified membrane, on the other hand, doesn’t torch well so it is loosely laid and bonded only by heat fusion.
What is it for?
Since they provide exceptional protection against environmental elements, torch-on membranes are best for flat or low-sloped roofing, balconies, areas that easily collect water and areas where foot traffic is high, as the solution can be applied with a non-slip aggregate to ensure slipping is not an issue.


LOOSE-LAYERED SHEET MEMBRANES

What is it?
As opposed to self-adhesive sheet membranes, loose-layered sheet membranes are highly flexible thermoplastic commercial waterproofing products usually made from polyethylene film, plasticised PVC or thermoplastic polyolefin.
They are laid on top of new or existing floors, used to control dampness of the flooring. Unlike other types of waterproofing systems, loose-laid sheet membranes are easy to install and quick to restore. When damaged, you need not replace the entire system as you can simply remove the affected sheet and fit a new one instead.
What is it for?
Loose-layered sheet membranes are a common choice as a damp-proof flooring membrane usually in performance sports centres, production lines, and other areas prone to injury.


HYPALON BANDAGES

What is it?
Hypalon is a relatively old waterproofing material, which is also known as chlorosulfonated polyethylene (CSPE) synthetic rubber (CSM). It is a popular joint and crack sealant, and is known for its high watertight properties and compression strength. While it effectively seals joints, hypalon bandages are preferred where multi-direction movement is required.
It is important to consider the environment when applying this solution however as beyond 30 degrees Celsius it will not yield the intended effect. Furthermore, while there are still hypalon concrete waterproofing materials available today, its manufacturer, DuPont, has ceased production of the product permanently.

What is it for?
Hypalon bandages were generally ideal for sealing tunnels, culverts, silos, roof connections, industrial floors, reservoirs, silos, and wastewater treatment plants.


TANKING MEMBRANES

What is it?
Made from polypropylene, tanking membranes are studded sheets that create a tank-like seal to serve as impermeable barrier to prevent water from penetrating through a building. The studs are responsible for the air gap cavity between the wall and membrane, which helps in keeping the covered area dry. Tanking membranes are also called cavity drain membranes.

What is it for?
Tanking membranes work well on any type of wall but because they perform greatly on masonry, it is a viable waterproofing solution for older buildings or heritage structures.


NEGATIVE WATERPROOFING THROUGH INJECTION

What is it?
Negative waterproofing is the go-to when it becomes impossible to carry out waterproofing from the external side of the structure. While it can prevent water from entering the space, negative waterproofing cannot stop moisture and water from getting into the substrate, meaning the water may still corrode the steel and concrete within causing concrete cancer.
The most common methodology applied in negative waterproofing is the application of injection to fill cracks and voids in between wall layers.

To resolve non-structural water penetration issues in places like basements and below-grade areas, chemical grout or polyurethane injection is applied, which effectively stops water pressure from increasing, thus causing serious structural problems.
What is it for?
As mentioned above, injection-based waterproofing is used for cracks on concrete walls, columns, seams and fissures, slabs, beams, and many more.

The Difference between Torch-On and Liquid Waterproof Membranes | Remedial Building Services

c

THE DIFFERENCE BETWEEN TORCH-ON AND LIQUID WATERPROOF MEMBRANES


So, there is a water problem in your building and you are now considering applying a waterproofing solution for either your residential or commercial property, but are not sure what’s best for your building? Well first off, it may be good to check our previous blog, Understanding the Different Types of Commercial Waterproofing.
Ok so you’ve read that? Ok well welcome back.
As a recap if you didn’t go read it again, a waterproofing membrane is the thin layer of water-tight material that is laid over a surface to protect it against water ingress. This “elastic” membrane is both durable and flexible, protecting your structure, and most importantly its resistant to external factors.
But with the variety of waterproofing membranes available for use in commercial structures, how do you know if your engineer’s choice is the right one for your property? In this piece, we will explain the advantages and disadvantages of torch-on and liquid membranes, as well as how each one works and why your engineer might recommend one over the other.

Torch-on membranes

What is a torch-on membrane?

Torch on Membrane applied to a decking areaTorch-on membranes are a type of waterproofing material that is made from a mixture of asphalt or bitumen and different types of modified polymers like Atactic Poly Propylene (APP), a plastic-modified asphalt, or Styrene Butadiene Styrene (SBS), a rubber-modified asphalt. The mixture is then coated on top of a polyester or glass fibre reinforcement to enhance its strength and resistance.
Torn-on membranes are sometimes called a modified bitumen system.

How are torch-on membranes applied?

The surface where the torch-on membrane system is to be applied must be thoroughly cleaned and scrabbled for all extrusions or problem zones. It must be free from dust, grease, oil, debris, and any other traces of contaminants. Likewise, all flaws must be addressed, including bulges, chips, and other imperfections which could cause depressions, or with time cause punctures in the membrane. With this done, a primer is applied in order to enhance the adhesion between the surface and the torch-on membrane.
Once this has dried, a qualified labourer will roll out (torch on membranes are in large rolls) the membrane using a butane torch to melt the bitumen and seal it to the surface. If APP-modified membranes are utilised, a cylinder or a hand torch is used to heat the sheet and expose a shiny bitumen surface that adheres to the substrate.  If on the other hand, SBS-modified membranes are used, heat fusion is applied to melt and bond the sheets that are loosely laid out on the surface. This takes more time than installing APP-modified membranes. Ideally each sheet has an overlap with the neighbouring sheet to ensure that there is a tight seal. The overlapping bitumen is pressed into the layer to ensure adhesion to the substrate and the neighbouring sheet.
Advantages

  • Highly effective as a waterproofing system for roofs and other areas that easily pool water

  • Doesn’t get damaged even when fully immersed in water

  • Super flexible and can withstand strong structural movements

  • Proficient in resisting vapour, chemical elements, and other harsh environmental factors

  • The exposed top-side of the membrane can be covered in an aggregate which adds a non-slip quality to the membrane.

Disadvantages

  • Installation can be a safety concern due to the presence of heat and flames.

  • Installation is more time-consuming compared to liquid membrane waterproofing system where spraying or application using a roller is much faster

  • Application is generally limited to flat roofing and surfaces

 

Liquid Membranes

What is a liquid membrane?

A liquid membrane is a waterproofing material composed of a liquid film usually in the form of polyurethanes, acrylic, or asphalt, with polyurethane elastomers comprising the most common material utilised. Liquid membranes are easy to apply as they are by their nature, fluid, meaning they easily take the shape of the surface it is being applied to. They can be cold-applied or hot-applied.

How are liquid membranes applied?

Before application, the surface that needs waterproofing must be cleaned, dried, and levelled to ensure a smoot surface. Post this, a water-soluble epoxy primer must be sprayed, rolled, or brushed on the now-clean substrate.
The exception to the rule however, is where the surface has a high-moisture level (above 4%), in which case a two-component polyurethane primer must be used instead of an epoxy primer. With this complete, the liquid membrane can then be applied by spraying, rolling, or brushing.
It is important to note that cold-applied membranes cure into permanent waterproofing membranes, so make sure that the application is final since they cannot be repositioned.
Advantages

  • Works best in corrugated roofing and bumpy surfaces as well as flat areas, differentiating them from torch-on membranes that are limited to generally flat substrates

  • Depending on the size of the area, application can generally be done within a day,  as liquid can be directly sprayed, brushed, or rolled into the substrate unlike sheet membranes that need to be overlapped and properly positioned before melted and applied into the surface

  • Allows you to save on labour cost since application is fast and straightforward

  • Impressive longevity that can provide a tight water seal for several decades

 
Disadvantages

  • Application is permanent; cannot be removed or repositioned

  • Requires extraordinary diligence in application since liquid systems are sensitive to temperature and will not seal properly if applied outside of the application temperature range

  • Uneven thickness will result to ineffective waterproofing, thus requiring reapplication

Which waterproofing solution is better?

Torch-on membranes and liquid membranes have their individual strengths and weaknesses. Your engineer might recommend one over the other depending on the type of surface that needs waterproofing (corrugated or flat), the environment your structure is built on (Is it near the water? Is it prone to salt exposure and corrosion?), your budget, and many other factors.

If you think that because a building is made from concrete and measures have been taken to protect it that it will thus be impervious to water, you may need to think again. Protecting a building from water is something that people often take for granted. They think concrete structures are impervious to water, but sadly, they are not. Chemicals and minerals which help give concrete its strength, can also be the proponents which react with chemicals in water and other liquids which ultimately lead to concrete spalling.
And though you may believe that building has adequate drainage to prevent the build-up of water, and thus minimise the chance of your foundations being affected, did you know that most waterproofing issues we fix are to the flat roof areas and the decks which sit above carparks? If these spaces are above residential spaces such as in an apartment, the impacts are real and tangible for those residents, whereas if the affected area is a commercial building or carpark, the impacts are often financial.
In this blog, we want to provide you with an overview of different issues caused by water and then provide insights into the different methodologies/options available to you for the protection of those areas subjected to water.
