Waterproofing in buildings is of critical importance, especially for our country, which is located in an earthquake zone. With the “Water Insulation Regulation” put into effect in the past years, the principles of insulation have been determined. Accordingly, waterproofing is required to prevent buildings from being damaged by water or moisture.
What is Waterproofing?
Applications made to extend the life of buildings and to make them resistant to abrasion, corrosion and leaks are called waterproofing. Waterproofing is done to prevent water or moisture from damaging the structure.
Waterproofing is necessary for the longevity and reliability of buildings. Waterproofing is made to protect against environmental factors such as rain, hail, snow, humidity and groundwater. In addition, water insulation is made so that bathroom, toilet and kitchen waters do not damage the building.
What are the Application Areas of Waterproofing?
Buildings have areas in contact with water, which are defined as wet areas. These areas are terrace roof, bathroom, kitchen and toilet. The building is in direct contact with water in many areas. For this reason, waterproofing is done in many areas in buildings.
Areas with waterproofing are defined as follows:
- Foundation and floors
- Walls and facades
- Exterior walls
- Roofs and terraces
- Window edges
- Water tanks
- Wet areas such as kitchen, bathroom and toilet
- Basement areas
Walls and facades, terraces and roofs, foundations and floors, pools and private areas are areas where water insulation is made. Attic and terrace sections of houses are important for waterproofing. Adverse weather conditions such as rain, snow or hail damage roofs and terraces. In this case, the water on the roof or terrace leaks into the building. Terraces and roofs should be waterproofed in order to prevent water leakage and run-off in the building.
What are the Advantages of Waterproofing?
Waterproofing has many advantages. Waterproofing primarily protects the building against water leaks. It prevents the formation of organisms such as mold, black spots and fungi on the indoor surface. Waterproofing prevents natural materials from rotting and plasters from swelling.
Waterproofing protects the building against corrosion and wear. It prolongs the service life of structures against the negative effects of water and humidity.
How Is Water Insulation Made?
While the building is under construction, waterproofing must be done. During the construction of the building, waterproofing is applied to the points that need to be applied. Insulated areas must be properly insulated.
Waterproofing of Foundation and Retaining Walls
The waterproofing of the foundation and retaining walls is applied during the construction of the building. In this vein, the surface must be prepared smoothly. The parts on the surface should be scraped and prepared for application. The use of liquid membranes is common in the isolation of foundation and retaining walls.
Waterproofing of Floors
Waterproofing the floors of buildings helps prevent water from seeping in and collapsing. In order for the buildings to be long-lasting, waterproofing should be done. With floor waterproofing, the structure is protected against water damage. Floor waterproofing is done in subway and tunnel constructions, during the internal insulation of basements and walls, on floors and horizontal joints in areas that may be exposed to water.
Waterproofing on Terraces and Roofs
Bituminous, acrylic or polyurethane materials should be used for waterproofing on terraces and roofs. When waterproofing terraces and roofs, the surface must be prepared perfectly. For application, it is mixed by pouring water into the insulation material. Then, the insulation material is applied to the terrace with the help of a roller brush.
Best Waterproofing Material
The best waterproofing material is chosen according to the requirements and conditions. If waterproofing is to be done for the foundation and terrace, membrane material should be used. Waterproof liquid membrane is often preferred due to its ease of application and longevity. The liquid membrane, which is completely waterproof, is easy to clean.
