Achieving effective weatherresistance surfaces is not as easy as it seems. Lack of knowledge leads to many misconceptions, resulting in poor waterproofing outcomes. Opting for a quick fix when a problem occurs may lead to higher repair costs in the long run. As such, property developers, construction professionals and homeowners should consider waterproofing as a long-term investment to safeguard their spaces as and when such issues arise. Waterproofing is a key component throughout any construction process to ensure that the building remains structurally intact and maintains its aesthetic look and feel for years to come. With this, understanding waterproofing basics including differentiating the various types of products to be used, identifying underlying problems and areas that require waterproofing is essential. Using proper products and suitable waterproofing systems will prevent recurring issues such as dampness and leakage that can deteriorate a building’s aesthetics or leading up to more severe problems such as structural damage over time. Choosing to repair the recurring damages from the cracks, blisters and mould caused by damp surfaces will incur an increased cost compared to if proper waterproofing were installed once and for all in the initial construction stages. Waterproofing provides a sense of security for building occupants and homeowners alike; it provides a solid foundation for any upcoming construction work and protects occupants from adverse health effects due to the growth of mould and mildew that may arise from excess moisture in the air. COMMON MISCONCEPTIONS A common misconception of waterproofing is to use a one size fits all approach, implementing one waterproofing system throughout all spaces at home. In fact, different building typologies require different waterproofing solutions throughout various spaces within the building (e.g. kitchen, bathroom, swimming pools, rooftops, etc.) and may require different waterproofing systems as well. When taking into consideration waterproofing solutions for respective spaces, it is essential to opt for holistic coatings solutions that are suitable for each type of surface. WHAT TO CONSIDER BEFORE WATERPROOFING Gutters are susceptible to cracks, buckling and leaks, as such, waterproofing efforts will go to waste without well-maintained gutters. Prior to waterproofing any spaces, regular inspection of the guttering system is mandatory to ensure that the brackets are not rusty. Proper sealants should be used around the joints to ensure that any unwanted leakage does not occur, as it may affect the overall quality of the waterproofing solutions applied. When assessing large surfaces areas such as rooftops, a thorough inspection must be carried out around the flashing (the metal used to seal bends and joints around vents), skylights and chimneys to ensure little to no damage. If tiles or shingles are missing, cracked or have deteriorated in quality, they should be replaced or fixed prior to the waterproofing process. As rooftops, especially flat roofs are most susceptible to damage, they must be properly cared for and the tiles should be securely in place. Otherwise, it may lead to water leakage into the building which may lead to other issues. Waterproofing may be needed, such as by using a spray-on foam insulation underneath the roof. WATERPROOFING DO’S 1. A Sturdy Structural Design A good, sturdy design and structure will support any waterproofing system because this will prevent the accumulation of water or moisture in the area. For example, the more quickly a cladding system can dissipate water, the greater its capacity to resist water intrusion. However, where there is complicated detailing such as unnecessary plane changes or complicated patterns, it will be less resistant to water leakages. For example, the design of a retaining wall in a residential area that is prone to flooding should avoid unnecessary detailing and the use durable materials such as concrete and marinegrade plywood. The waterproofing solution should give vertical protection against perched water as well. Designing a shoring wall system will require even higher level of performance and the solution should also be compatible with cast-in-place poured concrete and various shoring applications, while protecting against nuisance water, contaminated vapours and methane gas. 2. Selecting Durable Materials Sealant failures are common hence regular maintenance is necessary to prevent water intrusion within the failure of sealant joints. Aside from this, holistic waterproofing solutions should be put into place. Selecting appropriate materials for the cladding, flashing and detailing process are critical to ensure that it serves its purpose in the long run in providing effective waterproofing solutions for respective spaces. Components that are not easily maintained should have a service life equal to the overall cladding system. Factors such as cost, durability, and appropriate detailing requirements should be carefully evaluated when selecting a flashing. Plastic and rubber flashings are popular for their lower initial cost; however, stainless steel and copper flashing are more durable despite the higher cost. WATERPROOFING DON’TS 1. Don’t Assume A One Size Fits All Approach When developing plans for waterproofing solutions and selecting the appropriate products, it is essential to determine the exposure conditions because this will influence the requirements of the overall waterproofing system performance of respective spaces. Materials or cladding components shouldn’t exceed the performance limits. For example, a cladding system within a sloped wall application will have more skyward exposure. The moisture loads will be higher as it will be exposed to more sunlight and rainwater. If the material used is that of commonly used for vertical walls, the performance limits will be exceeded. With vertical walls, the pattern of wetting during a rainfall event is typically concentrated at the top of the wall and at the corners. In a sloped application, the entire surface will be exposed to rain. Thus, instead of opting for conventional methods of waterproofing walls, a sloped wall assembly should be treated like a roof from a waterproofing perspective to ensure minimal leakage and recurring issues. Waterproof performance relies on appropriate detailing and proper integration of system components such as weather resistive barriers, flashings, sealants and coatings. The use of incompatible materials can prevent otherwise appropriate details from functioning as intended. Do-it-yourself projects with a selection of unfamiliar materials or material combinations must be avoided. Professional consultation when making product selections is recommended to ensure that suitable waterproofing solutions are applied accordingly to the requirements of each type of surface.

Water is an essential source of life and prosperity and plays a vital role in maintaining our health, grow our food or in managing the various aspects of life.For the construction industry, water is a vital component as it is required in the production process for many building materials such as concrete, steel and paint. However, water is also considered as a major threat during construction projects. Water seepage and leakage – due to environment condition or internal piping system – can lead to many arising issues ranging from wood warping, metal fabrication turning to rust, mould growth, bubbles forming under the paint and in worst cases buildings failures, all of which affect the structural integrity, as well as jeopardizing the safety and health of the building occupants.The phrase “prevention is better than cure” says it best; buildings – from private homes to commercial properties, both new and old – need to be protected against water ingress to avoid expensive and irreversible damages. Building owners, developers and architects are now paying closer attention when designing the project masterplan, going through every detail including fixtures and fittings with a fine-tooth comb to eliminate any possibility of water-related issues during and after construction. Even so, this could not guarantee long-lasting protection throughout the lifespan of the building. Importance Of Waterproofing When it comes to safeguarding a building against water ingress, there are two possible solutions – damp proofing and waterproofing.Damp proofing is a coating, usually asphalt-based, that is either sprayed on or hand applied to the outside of the wall to keep out soil moisture, whereas waterproofing is designed to specifically keep out both moisture and liquid water. While both are commonly used solutions, waterproofing is the preferred choice as it provides complete protection from unwanted breach of water in both interior and exterior areas of the building. There are three types of waterproofing materials including liquid applied, cementitious and sheet type waterproofing membranes. Amongst these, the most common and widely used solutions are the liquid applied and sheet type waterproofing membrane. Some owners and contractors often seek a bargain when comparing waterproofing materials without fully understanding that different membranes can produce different results and may not be suitable for their site conditions. This eventually results in inadequate protection against water ingress, not to mention incurring further costs to hire contractors to assess for water leakage, and buying exorbitantly-priced building materials to repair any water damaged area. In recent years, expensive remedial work to correct failures in below-grade waterproofing systems has motivated owners and designers to seek high-performance and reliable waterproofing solutions. Riding on the current market trend and driven by technology and innovation, Malaysia’s No. 1 coating solutions provider Nippon Paint, has been developing new waterproofing solutions to enhance the durability of buildings, and homes - suitable for different types of surface from floors, walls, roof to ceilings, amongst others.

Do not be penny wise and pound foolish when it comes to waterproofing your building. It may sound like an unnecessary and negligible task but reports have shown that waterproofing accounts for only 1% of a building’s construction cost but when ignored, can be responsible for up to 90% of the cost of damages due to leaks! When a proactive approach is not taken to address this issue early on, it will result in structural breakdowns, leaks and mould leading to expensive rectification works. This was one of the observations during site visits for the recently concluded EdgeProp Malaysia Best Managed and Sustainable Property Awards 2020 organised by EdgeProp Malaysia in partnership with Nippon Paint Malaysia. So what happens when leaks are left unchecked over time? Besides damaging the paint on the walls and the wall itself, it will also cause ponding on ledges and sills leading to stains, delamination and fungi growth, thus creating health hazards for building occupants. Malaysia’s hot and humid climate encourages the growth of microorganisms where there is trapped moisture. Fungi and other invisible enemies in the air can affect the health of those residing in the building as they can cause respiratory illnesses such as asthma attacks and other irritations and infections, especially for those who are more vulnerable like young children and the elderly. Furthermore, stagnant water from water leaks is also the perfect breeding ground for mosquitoes leading to illnesses such as dengue fever. On top of that, ponding or pooling of water is especially dangerous when you have young children and the elderly moving about as the slippery surface can result in unwanted falls. Challenges In Waterproofing Waterproofing is a technical task that requires experts to make sure the solutions are applied in a correct manner. Without the correct surface preparation and application method, the waterproofing process might be jeopardised and cause further damage to the building. For instance, to waterproof concrete walls or floors you must first ensure that the surface is clean and dry. Old paint must be removed from the surface and the area needs to be cleaned to ensure no dirt is left behind. If necessary, a warm water and soap mix can also be used to scrub off dirt from the walls and floors. Holes must be patched using hydraulic expanding concrete mix and a minimum of 24 hours of drying is needed before any waterproofing work is done. It is also important to distinguish the difference between damp-proofing and waterproofing. Damp-proofing keeps moisture out of the surface while waterproofing keeps both liquid and moisture at bay. When in doubt, get professional help. Waterproofing solutions provider such as Nippon Paint strives to help by providing its expertiseand advice in the pre, during and post-waterproofing process. Solutions Having worked closely with their counterparts in China with a long standing presence in the waterproofing industry backed by knowledge and evolving technology, Nippon Paint has contributed to the completion of several iconic projects such as the Hong Kong-Zuhai-Macau Bridge and the Beijing-Shanghai High Speed Train.

They can be applied to obtain the desired specified thickness in a single trowel application. Depending on the type of surface and condition of the area, getting an expert to advice on the suitable waterproofing methods and surface preparation is vital so that the process can be done in the right way from the very start. Some Waterproofing Methods Liquid-Applied Membrane Method This liquid-based and fully bonded, monolithic coating is suitable for many roofing and waterproofing applications. It cures to form a rubberlike elastomeric waterproof membrane and can be applied on various substrates such as concrete and asphalt. Cementitious Coating Method This cement-based modified with acrylic polymers method makes use of the polymers to improve elastic and adhesion properties while the cementitious materials provide the tensile strength. The coating prevents water ingress and makes the coating elastic. Sheet-Type Based Membrane Method One of the most common types of sheet-based membranes is the bituminous waterproofing membrane. Arriving in the form of rolls, it has to be unfurled and laid on a firm surface before it is stuck to the substrate with a hot tar-based adhesive using blowtorches. Consequences Of Not Waterproofing Your Building Structural breakdown Ponding at ledges and sills Stains, delamination and fungi growth Damages external wall painting Respiratory illness Slippery surfaces which can cause falls NIPPON PAINT (M) SDN.

Waterproofing is often on the lower priority or excluded when planning for the pre-construction process, focusing on other factors such as design specifications and site preparation. To add on, waterproofing is also one element that increases the overall construction budget more often than not due to the complexities of the process. But living in a country that is susceptible to constant thunderstorms, rainy weather and frequent monsoon seasons increases the risk of damage to surfaces in the long run, deteriorating the building’s aesthetics as well as the quality of the interior and exterior surfaces of the building. Waterproofing is an investment that is surely worthwhile, benefitting property developers and owners in the long run. Why Is Waterproofing Necessary? The use of proper products and Coatings systems will build a strong waterproofing foundation for buildings, regardless of building typography, protecting surfaces from risk of long-term damage. Waterproofing is essential to help reduce moisture levels in the interior surfaces, preventing water damage and structural breakdown across common surfaces such as walls, ceilings, basements, floors, rooftops and, bathrooms. Insufficient waterproofing systems often lead to recurring problems caused by water leakage including cracks, blisters and mould – which produces mildew and spores that may potentially lead to respiratory problems in individuals. In the long term, repairing and regular maintenance for such problems will be more costly and ineffective than preventing these issues in the first place. A Waterproofing Checklist Waterproofing system and coatings varies for different buildings typologies, depending on the conditions and areas the buildings are situated during the pre-construction phase. Whether restoring older buildings, or working on new projects, it remains critical to take into account these considerations to protect structures for the long run: Assess the current underlying conditions and issues of the buildings prior to the development and construction process Before starting work on implementing waterproofing systems, a thorough assessment is required to ensure the correct waterproofing solutions are applied according to the nature of the premises. There are various types of waterproofing membranes (i.e cementitious membrane, liquid membrane sheet membrane amongst others) to be considered according to building specifications, complemented with an effective design which ensures optimum feasibility of the solutions. For existing structures which require certain waterproofing solutions to be applied, prior repair or maintenance work may be necessary to ensure that the waterproofing system when applied, is effective. Identify areas that require waterproofing systems While areas such as the bathroom, rooftop, kitchen and swimming pools typically require waterproofing, other areas such as balconies and basements also require end-to-end waterproofing systems to adequately protect these structures from water damage. Waterproofing areas that are made out of concrete such as balconies and basements creates an added level of protection, preventing cracks from forming and protects the space from direct UV rays which are detrimental to the longevity of the area. Waterproofing also prevents the growth of mould and mildew, which consequently leads up to other recurring structural issues. Durable solution is key Waterproofing solutions are a long-term commitment for any structure, providing a strong and sturdy foundation, and thus it is important to ensure that the selected waterproofing system is durable. Weigh the pros and cons upon thorough assessment of the premise to ensure that the solution chosen is long-lasting, cost-effective, but also minimises the need for maintenance or repair works over time.
