    Leaks from balconies are common, especially in older homes, and can cause significant damage if they are allowed to continue unchecked. It is important to keep in mind that termites are drawn to damp areas. If you already have fungal growth around your home, the last thing you need is an infestation of termites. If your balcony is leaking, it is essential to take action to fix the problem as soon as possible, before it leads to more serious complications. The process of waterproofing a balcony does not have to involve extensive renovations; by using a balcony sealant, you can have a balcony that is impervious to water in as little as one day and at a cost that is significantly lower than removing the tiles and replacing the waterproof membrane... or spending thousands of dollars in the future to repair the damage caused by termites.

    How to Waterproof Decks and Balconies

    To begin, it is essential to take into consideration the position of the deck. Because the deck may be buried in some circumstances or left exposed in others, making it vulnerable to wear and tear caused by the environment, it is imperative that the appropriate products be specified in order to accommodate the final purpose of the deck. Given that balconies are typically elevated from the ground, the available product options are typically less complicated.

    How to Decide Which Products to Use

    Deck and balcony waterproofing products should have a very good bond to the substrate they are applied to, and this is especially the case where the deck is exposed to the elements and subject to wear and weathering. In this situation, the deck waterproofing materials will also need to be able to deal with UV rays and be slip-resistant.

    Newton provides a diverse range of products for the purpose of waterproofing concrete decks. These products cover all possible applications, and include both vapour-permeable and vapour-impermeable options, in addition to a variety of primers, wearing coats, multi-coat systems, and drainage membranes. The product or products that are selected for the project are highly dependent on the intended use, as well as the location of the area. For instance, the product selection for a deck that is open to the elements would be different from a scenario in which the deck is covered.

    The technical experts at Newton can assist you in developing a solution that is tailored specifically to the needs of your project.

    What to consider before waterproofing

    In newly constructed homes, it is the designer's responsibility to select the most effective method of waterproofing for the outdoor flooring. The application of a drainage membrane on the reverse side of the substrate, which acts as a support for effective waterproofing, is a Best Practice that has been widely adopted and is now considered standard procedure. In point of fact, the regulations UNI11493-1 state that "the indication of a drainage and protection membrane, applied between the substrate and water barrier, is a measure with the objective of preventing water stagnation from penetrating the structure." This is a measure with the goal of preventing water from becoming trapped inside the structure.

    On the other hand, when it comes to renovations, it is essential to evaluate a variety of factors in order to select the most appropriate solution based on a set of fundamental requirements.

    In this particular instance, the first thing that needs to be analysed is the region in which the intervention will be carried out:

    • Determine the level of damage that has been done to the flooring and the substrate.
    • Check that the layered portion of the structure is correct.
    • ensuring that the slope of the flooring is appropriate is very important.
    • Make sure there aren't any cracks or gaps between the different layers you're looking at.

    You are free to choose the solution that is most suitable for the terrace or balcony in question based on the information provided in the following list of options.

    Choose the most suitable waterproofing solution for renovations.

    You are able to select the optimal solution for the terrace or balcony by analysing a number of factors and basing your decision on those findings. It is possible that directly waterproofing the floor covering is all that is necessary if the flooring is in pristine condition.

    On the other hand, if there are problems with the tile, such as cracks or holes, it is a good idea to remove them and then waterproof the layer that is underneath them, which is known as the substrate. If the condition of the substrate is also inadequate, the best solution is to waterproof the layer beneath the substrate, which will prevent any potential infiltrations in the future. This will be the case if waterproofing the layer is the best solution.

    Waterproofing solutions without removing the tile

    Liquid waterproofing is an excellent solution that can be utilised in place of having to remove the tiled surface if the flooring is in good condition and does not have any cracks or tenting. It is simple to apply and can be rolled or brushed onto the entire surface in a short amount of time without leaving any gaps, all while producing a thickness that is only a few millimetres in height. This method, which should be carried out by attentively following the instructions indicated by manufacturers of liquid membranes, is resistant to changes in temperature, inclement weather, chemical substances, or stagnant water. It should be carried out by carefully following the instructions indicated by manufacturers of liquid membranes. The compatibility of the product with the flooring that is already there is an essential factor that must be discussed with the provider.

    Waterproofing solutions between tile and substrate

    If the flooring is damaged or not suitable for use, it is necessary to remove it and completely intervene in the layer underneath, which is on top of the substrate. This is required in the event that the flooring requires replacement. There are a few different options available for waterproofing, but the two most common ones are waterproofing membrane rolls and waterproofing liquids.

    Rolled membrane waterproofing systems

    There are a lot of different ways to waterproof the substrate using rolled membranes, and you can find those solutions on the market. Bituminous, rolled, self-adhesive waterproofing membranes that can be applied on site via hot air welding are the most common type of this type of membrane.

    The substrate needs to be spotless, devoid of dust and debris, and completely dry. After the adhesive membranes have been applied, thinset can be spread in preparation for the tiling process.

    In the event that the water-resistant layer that lies beneath the substrate has not been compromised, you will be able to implement a solution that is both more hygienic and more expedient, such as a rolled-up polythene membrane. Floortec, a membrane with a base in polythene that has been laminated with non-woven fabric on the underside, is what we recommend using for this particular kind of waterproofing so that you can put it to use. Floortec, which has a total thickness of only 3 millimetres, not only reinforces the waterproofness of the substrate without significantly affecting the interior of the flooring, but it also compensates for structural tension, manages moisture that rises through the installation, and provides additional load resistance. All of these benefits are provided despite the fact that Floortec only has a total thickness of 3 millimetres. After the membrane has been adhered to the cement subfloor using an adhesive cement, the tiles can be put down.

    Cement-based liquid compound waterproofing system

    On top of the substrate, the application of a cement-based liquid layer that is straightforward to spread could be considered an alternative to the use of a bituminous membrane. The final product is a mixture that is based on cement and to which polymers and other elements that are water-resistant have been added. After that, the tiles and the adhesive designed specifically for tiles should be placed atop this layer. This procedure is less complicated than the one that came before it. However, in actual practise, the cement layer is not completely waterproof. It is possible for the cement layer to swell or contract as a result of changes in temperature, which would allow a small amount of moisture to pass through to the layer below. This method is strongly suggested for use in restoration projects in which it can be established beyond a reasonable doubt that the substrate is in pristine condition and does not contain any cracks or even minute fissures.

    Waterproofing solutions under the substrate

    Intervening under the substrate is the most effective way to both solve the problem of infiltration and prevent any further degradation from occuring. According to regulation UNI11493-1, the process should include the application of a waterproofing layer, on top of which is applied a drainage membrane that both provides protection and allows the outflow of water that percolates from the upper layer of the draining substrate. If you want the best possible results, the waterproofing layer should be applied first, followed by the drainage membrane.

    Bituminous membrane waterproofing system

    When it comes to waterproofing the area beneath the substrate of terraces and balconies, the most common method is to use bituminous membranes. The distillation of crude oil results in the production of these membranes, which are then packaged and sold in prefabricated rolls for commercial use. In addition, there is a resistance-boosting armature embedded within the roll's thickness. This armature can be made of glass fibres or polyester fibres. It is recommended that a bituminous membrane be applied in pedestrian areas with a thickness of 4 millimetres. This is done in order to increase the mechanical resistance and maintain the elongation property that is characteristic of this material. Examples of pedestrian areas include terraces and balconies. The sheets of prefabricated rolls have flame bonding, which makes them simple to instal and ensures that they adhere completely to the surface.

    These same membranes are also available with an adhesive layer, which can be used in settings where an open flame cannot be used in the application. These are more convenient to use, but their effectiveness is slightly diminished as a result.

    The importance of draining membranes

    Drainage membranes installed beneath the substrate of the building are true heroes for the building's structural integrity.

    The most significant factor in the deterioration of balconies and terraces is, in point of fact, the presence of water, which causes damage when it inevitably penetrates the interior of the substrate and wears away at the numerous waterproofing layers over time. This kind of issue is never an issue because of the distinctive construction of the drainage membrane. For this reason, we recommend Draintec 8, a membrane that was designed by our technicians to allow water drainage through a series of drainage channels while compensating for the hydrostatic tension that occurs when the substrate and the bitumen-based membrane are in contact with one another. The unique shape of this item both supports the load and lessens the load compression that occurs as a result of pedestrian or load passage. Draintec 8 consists of two glued layers despite having a thickness of only 8 millimetres. The first one is a polythene base with elements in the shape of cones that are used to separate liquids and drain them. The second layer of the membrane is a non-woven fabric that is laminated on top of the base. This layer has the purpose of preventing small particles and debris from passing through the membrane in order to prevent the channels from becoming obstructed and reducing the membrane's overall efficiency.

    When utilising a substrate that drains water, we recommend installing Draintec 8S, which is made up of a nett with a more open weaving structure than that of Draintec 8.

    Using a perimeter profile for optimal results

    Installing the Border Tex BD profile all the way around the perimeter of the terrace or balcony is something we recommend doing if you want an intervention to turn out with state-of-the-art results. This edge profile's objective is to ensure that water completely drains away by utilising drainage holes that have been purposefully designed for this purpose. It is recommended that the Bordertec BD be placed underneath the substrate, specifically in the space that exists between the drainage membrane and the bituminous membrane. It is the ideal product to protect the structure of the terrace from infiltration and deterioration, particularly when used in conjunction with the Draintec 8 drainage membrane.

    Balcony Waterproofing

    The waterproofing of bathrooms and balconies are two of the most common areas in residential buildings that experience failure, and both of these areas can be very pricey to repair. Balcony waterproofing is especially problematic. You only get one shot at getting it right because removing the surface that people walk on in order to fix a problem at a later time is required, which is not the easiest thing to do in situations where tiles are used.

    Installing Butyl Rubber

    In the same way that other types of work require a well-prepared, sturdy, and reliable substrate, balcony waterproofing does as well. This substrate can be different from system to system, but a good rule of thumb is to provide a finish that you would be willing to tile over without the addition of any waterproofing material.

    Before The Waterproofers come to apply the waterproof coating on a balcony, The Waterproofers ask that no silicone or polyurethane be applied to the surface of the balcony. Quite frequently, we find that leak control flanges, also known as floor wastes, have been fitted with silicone and edge sealed. This silicone may cause some of our systems to malfunction, which will prevent us from carrying out our work. Before leaving the construction site, it is our understanding that the tradesmen will make an effort to create a watertight seal. Nevertheless, these actions may at times render it impossible for us to provide a solution that is acceptable to the client.

    The waterproofing of balconies can be accomplished with the application of virtually any of the product lines that we typically use. When deciding which solution would be most beneficial to your project, different systems each have their own unique set of advantages as well as specific factors to take into account. Please get in touch with us if you would like our assistance in determining which approach should be taken with the problem. On a balcony, we strongly advise you not to use torch-on bitumen membranes because of their combustibility. Even though they are considered to be a trafficable membrane system, they do not handle the stress of traffic very well on days that are warm to hot. When bitumen has been allowed to soften, it is more susceptible to damage and can be transferred to your shoes, where it can then be tracked into your home.

    Butyl Rubber Waterproofing

    Because it can be installed either beneath a screed or directly below the majority of surface finishes, butyl rubber is an excellent membrane for use in the waterproofing of balconies. Butyl rubber waterproofing can be applied to virtually any substrate, provided that the substrate complies with a minimum specification. These substrates include concrete, plywood, and cement sheet. In certain circumstances, the application of an epoxy primer comes immediately before the laying down of a butyl rubber waterproofing membrane.

    Once the butyl rubber waterproofing has dried, you will still need to apply a second waterproofing membrane to the screed in order to prevent any moisture from soaking the screed and/or efflorescence from rising from the screed through the finished surface. This is necessary when using butyl rubber waterproofing as a base for a screed. This membrane might be an additional layer of butyl rubber or one of the many different types of seamless liquid membranes that are on the market.

    A butyl rubber needs to be applied prior to the installation of door and window frames, and it needs to be bonded to the building framework (or masonry) prior to the installation of any wall finishes. This is something else that you should keep in mind when considering the use of a butyl rubber. This is particularly pertinent in light of the growing use of lightweight foam in construction, as evidenced by the leaky homes crisis in New Zealand, also referred to as "leaky building syndrome."

    The installation of finish materials, such as tiles or other types of finishes, is the last significant aspect to think about when butyl rubber is being used to waterproof a balcony. Because of the inherent properties of butyl rubbers, they are notoriously difficult to adhere to, and as a consequence, the majority of tile adhesives struggle mightily to produce bonds that are satisfactory. When discussing your project with us, it is in your best interest to bring up the topic of the finishing material.

    Seamless Liquid Waterproofing

    The waterproofing of a balcony using a liquid system is slightly less forgiving than the waterproofing of a balcony using a butyl rubber system; however, the liquid system can be performed later in the construction phase, thereby minimising the possibility of damage. The substrate should be prepared and made ready to accept the finished product, and in some instances, it may be necessary to apply epoxy primers in place of the standard primers.

    When waterproofing a balcony using a liquid, door frames and wall cladding do not need to be installed first like they do when using butyl rubber. Flashings should be fastened in an unsecured manner behind the cladding, and they should be well exposed onto the floor of the balcony in areas where the membrane does not encapsulate the entire wall.

    When it comes to final finishes, liquid waterproofing systems are also able to accept a wider variety of adhesives than other types. Again, these should be discussed prior to the beginning of the work in order to guarantee that compatible products are used.

    There are also some liquid membrane systems available for use in balcony waterproofing. These systems offer a watertight seal in addition to a finish that can withstand foot traffic in a single package. These systems are especially helpful in circumstances in which concerns regarding weight are of the utmost importance or in which costs must be kept under control.

    It's possible that you're already aware of how important it is to waterproof your outdoor deck when it comes to ensuring the safety of your home. Decks that are waterproofed protect the surface from water damage, which can include mould growth and dry rot. The process of waterproofing a balcony is one that you probably don't give much thought to very often. Continue reading to find out whether or not the waterproofing of your balcony is required and why it is important.

    You have the option of tackling this project on your own as a do-it-yourself project or calling in a professional contractor if you want to ensure the safety of your loved ones and the people you care about most in the world. Waterproofing your balcony is essential. This holds especially true if your balcony has a wood-framed structure, as failure rates for balconies with wood-framed structures are significantly higher than those of other types. Leaks, visible damages, and even invisible damages are all potential issues that can arise with wood-framed balconies. Dry rot is one of the causes of these unseen damages, which include structural damage. The structural integrity of wood can be compromised by dry rot from the inside out. Pressing down on a piece of wood with your hand or foot is one way to determine whether or not it has dry rot. It is likely that dry rot is present in the wood if it has a spongy texture and does not feel like a typical hard surface when pressed.

    Even if your balcony is made of concrete, that does not completely absolve you of responsibility for maintaining it. Waterproofing is an additional requirement for concrete structures. When you waterproof the concrete, you are providing it with an additional layer of protection against water damage. The process of waterproofing concrete also stops cracks from appearing, stops mould and mildew from growing, and protects against ultraviolet rays. This is especially significant because the majority of balconies are exposed to a significant amount of direct ultraviolet light. You should also take into consideration the fact that waterproofing your balcony will, in the long run, result in cost savings for you. It is almost always going to end up costing significantly more money to repair water damage to a deck than it would have to simply get the deck waterproofed in the first place. If you have a balcony, it is imperative that you discuss waterproofing with a trained professional.

    FAQs About Balcony Repair

    Bituminous membrane waterproofing system

    When it comes to waterproofing the area beneath the substrate of terraces and balconies, the most common method is to use bituminous membranes.

    A completely waterproof seal is produced above and below your deck when a Tufdek vinyl membrane is installed on a second-story deck, regardless of whether the deck is new or already in place. If you have a vinyl deck, the water will run off the edge of the deck rather than getting trapped in the cracks. Both the space underneath your deck as well as the space above it are totally safe.

    When applying Shower Plug or Resistain sealant, you can do so with a brush, roller, or spray. Sealant should be liberally applied to the surface after dipping the brush or roller in the bucket of sealant and then applying it. – Fill up the entire surface with the liquid. In order for it to be fully effective, it must absorb the maximum amount of liquid sealant that it can over the course of two coats.

    Your balcony can be resealed with epoxy regrouting, which eliminates the need to remove the tiles. a substance that can withstand the effects of both water and chemicals. It requires little to no maintenance and can withstand any kind of weather. As an additional safety precaution, we will also apply polyurethane silicone to all of the junctions along the perimeter.

    Tiles made of porcelain are readily available and have quickly become one of the most popular choices for the flooring material on balconies. The fact that these tiles are extremely dense and long-lasting makes them an excellent choice for use in outdoor settings.
