While waterproofing the terrace, there are several areas that must be addressed. Pipes coming through the parapet wall or the roof, small canals for cables and electric wires, terrace door thresholds, water tank corners, and so on are examples of such areas. Furthermore, rainwater drain outlets exiting the terrace must be of adequate size and made available all around the roof. Contact a KTC Group expert to determine the best solution for waterproofing your roof.
Your terrace or roof is the most exposed to the elements and is subjected to harsh weather conditions. This includes not only heavy rains, but also hot summers and cold winters. Such climatic changes typically cause thermal expansions in your home’s ceiling and may result in water seepage. Surface deterioration eventually leads to more damage. This is why waterproofing solutions must be applied over time.
Because the bathroom is the most wet area in your home, it is always a good idea to waterproof every corner of it. The floor is the most exposed, but shower walls are also wet up to a certain height. Bathroom waterproofing solutions are typically required to be applied at every corner and even on the side walls up to 20 cm from the base. If you notice dampness on the other side of the wall, use KTC Group bathroom waterproofing solutions to cover the affected areas.
Any waterproofing solution typically comes with a 10- to 15-year guarantee; however, this is dependent on the method of application and the proportion of the elements. You don’t need to re-waterproof your bathroom beyond this range if you follow the steps carefully.
Your bathroom typically has four leak-prone areas, namely the floor bed, the drainage pipes, the sanitary fixtures, and the shower areas KTC Group Pidifin 2K and Bathseal Tape and Grout are comprehensive systems that will help you make your bathroom completely leak-free for years to come.
Persistent dampness inside the house promotes bacterial and fungal growth, endangering the residents’ health. It can cause respiratory problems such as asthama, as well as frequent colds and coughs. Damp walls can also produce a foul stench, making living in the house impossible.
Your home’s exterior walls are one of the most vulnerable surfaces to extreme weather conditions. Water leakage is caused by even minor cracks in the plaster. To prevent seepage, you must use a superior waterproofing material to prevent water ingression from your home’s exterior surface. You can protect your internal décor by using KTC Group external wall waterproofing services in India.
To stop water leakage through walls, the source of the leak must be identified. The source could be rainwater seeping through window frame gaps or leaks from the roof, bathroom, or kitchen. KTC Group offers specialised waterproofing solutions for a variety of leakage issues. These water leakage solutions are designed to keep steel bars from rusting, cracks, and moisture from forming in ceilings, internal and external walls. Contact us to learn more about wall leakage.
Dampness in your home’s internal walls can occur for a variety of reasons. One of the most common problems in India is a high groundwater table. Similarly, wall cracks allow water to enter from the terrace and external walls, causing dampness. Cracks form as a result of extreme weather conditions. Traditional waterproofing methods are ineffective in dealing with seepage problems. KTC Group internal wall waterproofing solutions can assist you in resolving this issue. Forget the traditional method of breaking wall plaster; instead, scrubbing the internal wall dampness and applying the solution over it will suffice.
Water tanks are designed to safely store water without leaking. But it’s not just a matter of leaks here. The main issue is preventing fungus growth. You might be wondering how the fungus forms. Seepage and leakage from overhead and underground tanks can sometimes detract from the décor. This, in turn, promotes the growth of algae and fungus, weakening the structure. As a result, such areas should be made waterproof as well as potable water safe. You must use the appropriate water tank waterproofing method and products for KTC Group.
