    If you own a home in the neighbourhood, the last thing you want is for your structure to be considered an eyesore by the other residents there. When there are leaks or cracks leading into the interior of your house, then it can become an issue. This is something that we all want our homes to look like for our families and friends. This blog post will provide you with some helpful hints on how to determine whether or not there may be a problem with the waterproofing in your structure so that you can address the issue before it becomes more serious.

    What Is Waterproofing?

    The phrase "nearly impenetrable to water" best describes the result of the process known as waterproofing, which is performed on an object.

    In the context of the construction industry, the phrase "waterproofing" refers to the prevention of water and moisture from entering buildings.

    Although waterproofing and moisture management are components of a building's design, additional methods to address these issues can be implemented at a later time if necessary. A sound waterproofing strategy prevents water from entering structures and enables the efficient drainage of any water that is able to make its way inside the structure despite the strategy's success.

    Why Is Waterproofing Important?

    Waterproofing is essential because it prevents moisture from entering a structure, ensuring that those living within remain healthy and unharmed.

    Dampness is a consequence of insufficient waterproofing, which in turn results in a number of complications. Earlier, we discussed the mouldy mildew. Mold, of which mildew is a subtype, is not only unpleasant to the eye, offensive to the senses, and destructive to your possessions; it also poses a health risk to anybody who is exposed to it. It makes the air we breathe unhealthy and can trigger allergic reactions in people who are already susceptible to them. Your asthma may become much worse, and in extreme situations, it may even cause you to throw up, have trouble breathing, and suffer damage to your liver.

    An accumulation of fungi can also occur when water sits about doing nothing. It is possible for it to ruin the belongings that are contained within a structure by causing them to rot. Additionally, it may cause damage to the walls. Water can also cause structural harm to a building by making the foundation of the structure more susceptible to collapse. It is possible for it to seep into the foundation walls and then freeze there when the weather is cold, which will cause the wall to crack in certain spots. This is true not only of wooden structures but also of concrete ones.

    For this reason, waterproofing is essential to preserving the general health of a structure as well as the health of the people who live there.

    Need For Waterproofing

    One may remark that a building is a living organism that requires the appropriate care and upkeep because this would not be an incorrect statement. Additionally, it is imperative that problems brought on by moisture and water be avoided at all costs.

    The following are some of the ways in which water problems inside the building might cause damage to the structure:

    • leaking through the wall claddings, sills, expansions, beam-brickwork junctions, and other areas.
    • Absorption of groundwater in the flooring and voids of the basement.
    • It is caused by the rupture of pipes that are located within the wall or beneath the flooring surface.
    • The capillary network rises via the columns, joints, and walls.

    What Happens When Waterproofing Fails

    In spite of the fact that waterproofing may only account for a couple of or three percent of a building's total costs, flaws in waterproofing may be the root cause of eighty percent of a building's problems. When the waterproofing doesn't work, there are therefore substantial repercussions.

    • Security - The building may sustain such severe structural damage that it is no longer secure after the incident. Problems with liability and insurance can arise as a result of this situation for landlords.
    • Failures in waterproofing can result in concrete cancer, mould, and major structural concerns that render a home, workplace, or other facility uninhabitable. These issues can arise from prolonged exposure to moisture. This could result in a loss of rental income as well as significant costs for repairs.
    • Water that seeps into the building through cracks or other openings can cause extensive damage to the structure of the building as well as to the contents and furnishings within it.
    • Concrete cancer - Concrete in structures is generally reinforced with steel bars or mesh. Corrosion of the steel can occur when it is exposed to air and water, which can cause concrete to develop cancer. Following this, the steel expands, which causes spalling, also known as the cracking of the concrete around it. As a result of the increased exposure of the steel to the environment, the rate of corrosion has quickened. This malignant growth on the concrete is a typical complication of inadequate waterproofing.

    Common Causes Of Waterproofing Failure

    There are several reasons why waterproofing doesn't work, but the most common ones are sloppy craftsmanship, using a membrane that isn't designed for the job, or putting the membrane in place without first installing the rest of the system.

    Issues From Higher Levels

    When it comes to the waterproofing failing in a multilevel building, the higher levels can be a potential source of problems. Puddles of accumulated precipitation on the roof can cause issues with the waterproofing of the uppermost floors of the building. In example, flat roofs are more likely to gather an excessive amount of rain, which can then cause leaks and finally cause structural damage to the building. Inadequate craftsmanship on higher levels, such as faulty plumbing, can potentially result in a breakdown of the waterproofing system.

    Poor Waterproofing Work

    Inadequate artistry, including the use of the wrong installation methodology, can result in problems with leaks caused by the failure of the waterproofing. When it comes to applying waterproofing, difficult areas like balconies and windows require the assistance of a specialist. Inadequate artistry also involves incorrect product specifications, which occurs when the incorrect product is utilised, and insufficient substrate preparation, which refers to inadequate preparation before the waterproofing membrane is applied. Both of these issues occur before the membrane is applied.

    Lack Of Maintenance

    Regular maintenance in the form of inspections and corrective waterproofing enables you to spot any concerns in their earliest stages, allowing you to avoid major problems such as concrete cancer. As a result of the rapid escalation of water damage, it is imperative that even the smallest cracks and leaks be repaired without delay. This is because water damage can quickly lead to significant complications. It is also advised that you keep the seals that are already on your windows, doors, and wall systems in good condition. If you check balconies, roofs, and windows for cracks and leaks as soon as you become aware of them and take a proactive approach to maintenance, you can reduce the likelihood that a minor issue will escalate into a more significant issue.

    Wrong Choice Of Waterproofing Membrane

    Be sure to go with a comprehensive waterproofing system that comes with a sheet membrane as well as the rest of the ancillary components. When it comes to green applications, it is essential to take into account how resistant the membrane is to the sun's ultraviolet rays, chemicals, and harsh sea air, as well as root penetrations. The flexibility of the membrane is essential for accommodating building movements.

    Common Problems With Flat Roofs

    The most typical issue with waterproofing that the construction industry must deal with is the restoration of flat roofs that have previously experienced failure. To select a waterproofing solution, however, can be a difficult procedure because of all the aspects that need to be considered.

    The failure of the roof components or defects in the roof construction can have a significant impact on the occupants of the building, resulting in water ingress and the loss of thermal performance of the insulation material. Water ingress can also result in the loss of thermal performance of the insulation material (if any insulating is installed). In addition, the financial burden connected with the roofing works required to reinstate the roof's waterproofing integrity can be enormous. These roofing works are important.

    There is a possibility that the issue will not be easy to diagnose. There are a few possible explanations for why water could accumulate within the roofing layers.

    • Poor detailing around the perimeter and a failure at the upturn
    • Failure of the most superficial layer of weather protection
    • Detailing surrounding penetrations that is inadequate and lacking in quality.

    Using goods manufactured by Wolfin will help you save money while you are working on a project to restore your roof.

    You will not only save money by not having to pay for the costly component of stripping up and disposing of the old, failed membrane, but you will also be actively contributing to the conservation of the environment.

    Checking If You Need Remedial Waterproofing

    Your preventative maintenance inspections should ideally include an evaluation of the drainage effectiveness of roof regions, the plumbing system, and areas such as windows that are directly exposed to water and the elements. Keep in mind that it is essential to perform a comprehensive building inspection in order to repair any cracks or leaks as quickly as feasible. Even if they are located quite a distance from any sources of water, you should nevertheless inspect important sections such as roofs and balconies, in addition to living and working places.

    At the very least once every six months, commercial roofs should be evaluated. During this inspection, special attention should be paid to the vents, drains, and any other portions of the roof that may allow water to enter the structure. During the examination, it is important to search for stains in addition to cracks and leaks.

    As part of your routine maintenance, you should inspect the drains, plumbing, and irrigation systems. It is more likely that some portions of your building or site will have leaks that are difficult to locate; as a result, you should do regular thorough inspections of these locations. Even the smallest leaks demand your notice, and with some prompt action and corrective waterproofing, you may save money and retain the value of your structure. Even the smallest leaks warrant your attention.

    How To Identify If Your Building Has A Waterproofing Problem?

    If any of the following symptoms are present in your building, you can be certain that it requires a more advanced treatment:

    • Wet walls
    • The development of mould and fungus
    • Rotting signs
    • Pooling water
    • Observed seepage of water from the ceiling or the roof.

    In addition, all of these issues have the potential to demolish the outside structure of the building, in addition to causing damage to the interiors and the core foundation.

    Therefore, it is of the utmost significance to properly maintain our building and keep these difficulties at bay.

    Advantages Of Waterproofing

    • It maintains the structure's dryness and rigidity.
    • As a result of the reduction in the internal humidity, the building also becomes more pleasant for people to live in.
    • There was no harm done to the objects by the humidity or the water vapour.
    • Stronger and long-lasting building.

    Types Of Waterproofing Materials

    When you have a building, it is just as important to take care of it as it is to select the appropriate materials for it. Therefore, you need to have an understanding of the various types of waterproofing materials that might be used for your project.


    This is applied to the roof in order to weatherproof it. In addition, the polyurethane liquid membrane provides greater flexibility, in addition to various other advantages, such as the following:

    • Capillary fissures are filled up using material.
    • Also, a reduction in the water absorption capacity of the concrete.
    • The liquid causes the surface of the concrete to become more rigid.

    Application areas:

    • Water tanks
    • Pedestrian decks
    • Balconies
    • Roof
    • Bridges
    • Parking

    Cementitious Waterproof Coating

    The application could not be simpler using this material. Sand, compounds based on silica, organic chemicals, and inorganic chemicals are other components of the mixture. In addition, the combination of these chemicals with lime creates a sealant that is effective.

    Application areas:

    • Water purification facilities
    • Ports and docking areas
    • Parking
    • Tunnels

    Bituminous Waterproof Membrane

    This membrane is an effective barrier against the infiltration of water, and it is also known as an asphalt coating or a bituminous coating. A sticky organic liquid is combined with bituminous to form asphalt. Therefore, the fact that it is viscous makes it an exceptionally effective substance for waterproofing roofs.

    There are two different ways to apply bituminous material:

    • Method of using rolled roofing material
    • Roofing felt method

    The cost of bituminous membranes can range anywhere from one hundred to two thousand rupees (Rs.) per roll. This cost is determined by the feel, thickness, and length of the membrane.

    Note that despite the fact that the bituminous membrane provides exceptional defence against water, it can still be harmed by both high temperatures and ultraviolet light. It is possible to circumvent this issue by modifying the material using polymers based on acrylic or polyurethane, though.

    EPDM Rubber

    Propylene and ethylene are the two components that comprise this synthetic rubber substance that is used for waterproofing roofs. EPDM rubber solution is frequently associated in the minds of industry experts with a silicone compound. However, the chemical compositions, applications, and characteristics of each are distinct from the other.

    Additionally, EPDM rubber is extremely flexible and can be recycled.

    Application areas:

    • Roof
    • Windows
    • Wood

    Rubberised Asphalt

    Rubberized asphalt is another wonderful waterproof alternative that works efficiently to protect the home and its inhabitants. This material is not only strong and flexible, but it also allows moisture vapour to pass through it, which makes it very long-lasting and an excellent choice for the treatment of the structure.

    Application areas:

    • Roof
    • Plazas
    • Parking lots
    • Terrace
    • Also, cement chemicals of various areas at the structural masonry level

    Thermoplastic Waterproofing

    how to identify if your building has a waterproofing problem 3

    Thermoplastic is yet another type of material that is effective in waterproofing. Additionally, the protection afforded by this sturdy solution spans well over four decades. Therefore, because it is resistant to impact, it is an excellent choice for any treatment that requires a lot of force.

    Application areas:

    • Elevator Pits
    • Decks
    • Fountains

    Thermoplastics are handled by professionals. Because of this, the total cost varies significantly from one provider of services to another.

    Pvc Membrane

    This compound is typically utilised in the roofing industry as a waterproofing agent. Additionally, the fact that it is vapour permeable contributes to its already impressive strength. Polyester mesh or glass fibre may be found at the base of the PVC membrane.

    Application areas:

    • Roof
    • Swimming pools
    • Tunnels
    • Underground structures

    Waterproofing Paints

    The house is shielded from the deteriorating effects of the environment by the waterproof paint, which also extends the building's useful life. As a result, it either maintains its resistance to water or is entirely waterproof.

    Additionally, this paint is suitable for usage inside of structures, such as in bathrooms, kitchens, basements, and other such areas. Therefore, it prevents leaks and excessive moisture from entering the bathroom as well as the basement.

    The use of bathroom waterproof paint for the walls helps to prevent water from seeping through the walls. Therefore, conventional paints are not recommended in favour of these paints because regular paints will not be able to withstand moist conditions as well as these paints will. Mold and mildew will begin to grow as soon as moisture finds its way into the walls, which will cause the structure to deteriorate and may also lead to health problems.

    Types Of Waterproofing Paint

    Epoxy Waterproofing Paint

    Epoxy paints that are used for waterproofing make use of powerful ingredients to protect the surface from extremely wet circumstances and to fight against extreme wetness. Additionally, they make an excellent waterproof paint, which is particularly useful for waterproofing roofs and terraces.

    Masonry Waterproof Paint

    The waterproof masonry paint is typically utilised for application on rooftops. It is produced by combining latex and ceramic paint in equal parts. This paint has the ability to readily absorb chemicals and other liquids in addition to water, thereby preventing these substances from reaching the interior. In addition to that, it provides methods for waterproofing cement.

    Acrylic Waterproof Paint

    This kind of paint works particularly well in areas such as roofs and terraces that are constructed using rectangular blocks. Additionally, this roof and terrace paint causes the surface to contract, which forces water away from it. In addition to that, this paint for the roof is waterproof, in addition to being non-toxic and simple to apply.

    Work With Professionals For Remedial Waterproofing

    Working with waterproofing specialists gives you the best opportunity of achieving a successful conclusion with the restorative waterproofing. Stay away from attempting to remedy the issue on your own and instead have a professional waterproofing firm assess your site and complete the necessary repairs.

    Experts in waterproofing are able to assist with the selection of the appropriate goods for the location, as well as the application of the waterproofing membrane in the appropriate manner.

    A defective waterproofing system can have a significant negative effect on both the security and the market value of a structure. Inappropriate artistry, including the use of the incorrect product and improper application of the membrane, is frequently the cause of a failed waterproofing attempt. However, carrying out routine inspections and carrying out any necessary waterproofing repairs in a timely manner can assist you in preventing minor leaks and concerns from developing into severe problems.
