Waterproofing is the process of making an object or structure waterproof or water resistant. Thanks to this process, the insulated surface or structure resists water ingress.
In buildings, waterproofing creates a barrier to prevent water passage on surfaces that have high contact with water such as foundations, roofs, and walls. Thanks to waterproofing, building surfaces are strengthened and waterproofed. In short, waterproofing is a protective measure that makes a surface water-resistant and prevents liquids from penetrating undesirable surfaces under external forces such as hydrostatic pressure and capillarity.
Types of Waterproofing Materials?
It is possible to answer the question of what waterproofing materials are with many different products on the market. Each of these products has different usage areas. If the correct type of waterproofing material is not applied to the surfaces, the problems that will be encountered not only reduce the comfort of living spaces but also reduce the durability of the structure. For this reason, it is essential to apply the right insulation material to surfaces that are in high contact with water.
1. Cement Based Waterproofing Materials
Cement-based waterproofing is the easiest waterproofing method used in construction projects. It is easy to apply by mixing cement-based waterproofing materials.
This method is generally used in areas that are in the interior of the building and have high contact with water, such as toilets and bathrooms.
This method is generally used in areas exposed to high pressure such as pools and water tanks, and in humid places with high contact with water such as terraces, bathrooms, and basements. Cement-based waterproofing usually has full or semi-resilience but is not exposed to sunlight and weather conditions as it is used in areas such as toilets and bathrooms.
2. Liquid Waterproofing Membrane Materials
Another frequently preferred waterproofing method is liquid waterproofing materials. The liquid waterproofing membrane method is a thin coating, usually consisting of a primer coat and two coats applied by spray, roller, or trowel. It offers more flexibility than cement-based waterproofing types. For this reason, it is used more intensively today.
The durability of the waterproofing coating depends on what kind of polymer the manufacturer uses in the construction of liquid waterproofing. The liquid waterproofing membrane may be manufactured from a spray-applied liquid membrane consisting of polymer-modified asphalt. Separate grades of acrylic, hybrid, or polyurethane liquid membranes for trowel, roller, or spray are also available from a variety of manufacturers.
3. Liquid Bituminous Membrane Waterproofing Materials
Liquid bituminous coating is a type of coating used for waterproofing and flexible protective coating in accordance with its formulation and degree of polymerization. Its flexibility and protection against water can be affected by the quality of the polymer grade as well as the fiber from which it is produced.
Liquid bituminous pavement is also called asphalt pavement. The most common applications of liquid coatings include areas under the screed. It is an excellent protective coating and waterproofing material, especially on surfaces such as concrete foundations.
Liquid bitumen coating is made using bitumen rubber based material and is used on all horizontal and vertical surfaces. It is preferred for external insulation of areas such as foundations, cellars, and basements, and for the isolation of closed areas in the interior of the house such as bathrooms, kitchens, and toilets.
4. Membrane Waterproofing Materials
Membrane waterproofing materials are one of the most preferred waterproofing materials in the construction industry. This material; is also very preferred in roof insulation applications with its ease of use, and price/performance advantage. Membrane waterproofing covers are applied with the help of a torch flame source and thus adhere to the surface very well. Membranes that protect the building against all possible liquids and are sold in rolls can be produced in different thicknesses and models according to the area of application.
It is used under the coating in wet areas such as terraces and sloping roofs, balconies, flower beds, garden terraces, retaining and basement walls, sewage treatment plants, water tanks, ponds, swimming and ornamental pools, kitchens, bathrooms, WCs. It is also used in areas such as gardens and terraces that come into contact with the soil, thanks to its production as resistant to plant roots. Thus, it is used on the garden and terrace roofs of buildings that come into contact with the soil.
5. Polyurethane Liquid Membrane Waterproofing Materials
The polyurethane liquid membrane waterproofing method is used for the flat roof area and provides insulation of the roof against external factors. Highly flexible polyurethane liquid membranes are designed not to be affected by external factors.
Before applying polyurethane membranes, it is necessary to consider that they are sensitive to moisture. For this reason, it is necessary to evaluate the moisture content of the concrete slab before the application and to prevent the peeling or loosening of the membranes.
Uses of waterproofing materials
Waterproofing materials come into question when the need for waterproofing arises. That typically happens when the structural integrity of a building or a space is under damage or needs protection. The exteriors of a building are subject to harsh weather conditions, humidity, wind, climate and external water that can cause deterioration of the facade over time. Waterproofing is a process that is created to protect such structures from external factors like humidity, leakages, water penetration and water damage. The primary purpose of waterproofing materials is to create a protective barrier. The most common uses of waterproofing materials are as follows:
-
Roof waterproofing
-
Basement waterproofing
-
Foundation waterproofing
-
Balconies and deck waterproofing
-
Interior waterproofing
-
Exterior wall waterproofing
-
Terrace waterproofing
Benefits of waterproofing materials
Waterproofing materials have numerous benefits for buildings, residential spaces and commercial spaces. Following are some key benefits of using waterproofing materials:
-
Increased structural lifespan: Waterproofing protects building barriers from damage, deterioration and retains the newness of these structures.
Increased structural lifespan -
Prevention of Water Damage:This is the key benefit of waterproofing materials. It creates a thick layer of protection against water damage, infiltration or ingress.
-
Reduced Maintenance:Waterproofing materials give you longevity and durability thereby reducing your maintenance costs for leakages and repairs.
-
Prevention of mold and mildew: Moisture breeds mold and mildew growth. Waterproofing materials prevent moisture building in such spaces. This also creates good hygiene in residential spaces.
-
Energy efficiency: Waterproofing can help reduce energy costs by preventing moisture from entering the space because of its insulation properties.
Conclusion
Choosing the right waterproofing material in UAE is important for protecting buildings from water damage. Various types like cement-based, liquid membranes, bituminous coatings, and polyurethane membranes offer unique benefits. These materials ensure increased structural lifespan, prevent water damage, reduce maintenance costs, and stop mold growth. Proper waterproofing enhances the durability and hygiene of buildings, making them safer and more energy-efficient. Using the right waterproofing material is essential for maintaining the integrity of any structure.
