Waterproofing is a critical application to ensure the longevity of structures and to prevent water-related damages. In addition to traditional methods, polyurethane-based waterproofing products are increasingly preferred with the developing technology. Thanks to their high elasticity and excellent adhesion properties, polyurethane-based waterproofing materials provide complete sealing on surfaces and prevent water from damaging building elements such as concrete, steel and wood. With these features, their use is becoming widespread, especially in areas where water resistance is critical, such as terraces, roof coverings, parking lots and foundation insulation.
Polyurethane-based waterproofing products can be applied as one-component or two-component systems and are available with or without solvents. After application, they form a flexible membrane that bridges cracks and offers long-term protection by adapting to the movements of the structure. It also offers an effective solution in areas exposed to outdoor weather conditions thanks to its UV-resistant versions. Thanks to their easy applicability and durability, they are safely preferred both in new projects and in the restoration of existing structures.
Advantages of Polyurethane Based Waterproofing
Polyurethane-based waterproofing products stand out with their superior performance. Thanks to its flexibility, durability and ease of application, it offers an ideal solution for both residential and industrial buildings. Here are the main advantages of polyurethane based waterproofing:
Excellent Waterproofing Properties: Polyurethane forms a completely waterproof layer when applied to the surface. Thanks to its non-porous structure, it prevents water from leaking from the surface and provides long-lasting protection.
High Elasticity: Polyurethane coatings are resistant to movements that may occur on the surface thanks to their flexible structure. This feature prevents the formation of cracks in case of expansion or contraction, especially in building foundations, roof systems and terraces.
Ease of Application: Polyurethane-based waterproofing, which can be easily applied by spray, brush or roller, does not require joints or joints during application. In this way, integrity is ensured on the surface and possible leakage points are minimized.
Suitable for Different Surfaces: Polyurethane-based waterproofing, which can be easily applied to concrete, metal, wood, ceramic and even some plastic surfaces, has a wide range of applications. Thanks to this versatility, it is preferred in different projects.
High Chemical and UV Resistance: Polyurethane coatings show high resistance to chemicals and ultraviolet (UV) rays. This is a great advantage especially for waterproofing systems used in open areas. Resistance to UV rays prevents the coating from cracking or deteriorating over time.
Perfect Adhesion Feature: Polyurethane-based waterproofing materials adhere strongly to the surface to which they are applied and do not separate from the surface. In this way, it provides effective waterproofing for many years.
Long Lasting Use: Compared to other waterproofing methods, polyurethane-based insulations are longer lasting. With a correct application, it can provide durability up to 20 years and minimizes maintenance costs.
Jointless and Seamless Insulation: Polyurethane coating provides integrity on the surface as it does not require joints. The risk of water leakage from joints, which can be seen in traditional insulation materials, is eliminated in polyurethane applications.
Lightweight and Non-loading Structure: While some materials used in waterproofing put extra load on the building, polyurethane-based insulation materials do not increase the building load with their lightweight structure. This is a great advantage especially for high-rise buildings and light steel structures.
Environmentally Friendly Options Available: Modern polyurethane-based waterproofing materials are produced with solvent-free and environmentally friendly formulas. Thus, it does not harm human health and offers an environmentally friendly solution.
Polyurethane Waterproofing Usage Areas
Polyurethane-based waterproofing products are widely used in the construction industry and are preferred for their durability and excellent protection against water. Waterproofing is a critical factor for the longevity of buildings and structures. Polyurethane is used in various projects to meet these needs and its popularity is increasing day by day. Here are the areas where polyurethane waterproofing is widely used:
1. Foundation Insulation of Buildings
The foundations of buildings are exposed to the effects of groundwater, rainwater and ground moisture. Therefore, waterproofing the foundation is very important. Polyurethane waterproofing prevents water from seeping through the walls in contact with the ground, thus increasing the strength and durability of the foundation. Polyurethane seals and prevents evaporation, helping to ensure the longevity of the foundation area.
2. Roof Insulation
Roofs are one of the most exposed parts of buildings. Polyurethane is often preferred for waterproofing roofs. This material creates a flexible and waterproof layer that can be applied in various parts of the roof. At the same time, it quickly closes the cracks that may occur on the roofs and prevents water from entering.
3. Balcony and Terrace Insulation
Since balconies and terraces are located outdoors, they are constantly exposed to weather conditions such as rain, snow and sun. Polyurethane-based waterproofing also gives effective results in these areas. The polyurethane applied on balconies and terraces fully adapts to the floor surface, preventing water infiltration and preventing the accumulation of moisture inside the structure.
4. Insulation of Underground Structures
Areas such as underground structures, basements and parking lots are among the structures that can be directly exposed to water. Polyurethane waterproofing for these structures creates a strong barrier that prevents water from passing through floors and walls. Thus, the humidity in underground structures is kept under control and the life of the structure is extended.
5. Pool Insulation
Pools are areas where water is constantly present and water tightness must be ensured. Polyurethane provides excellent waterproofing when applied on the inner surfaces of pools. It also prevents water loss by instantly closing micro cracks that may occur in pools.
6. Exterior Insulation
Polyurethane insulation applied on exterior facades prevents water from entering the walls. Especially in rainy regions, waterproofing on exterior facades plays an important role in preventing water penetration into the interior of the building. Polyurethane material offers an aesthetically pleasing appearance and provides long-term waterproofing after it is applied to the exterior.
7. Use in Industry and Industrial Areas
Waterproofing in industrial plants and industrial buildings often requires high-performance materials. Polyurethane is an excellent option for waterproofing in such areas. Especially in places such as waste water tanks, water treatment plants, industrial pools, polyurethane-based products are used for waterproofing.
8. Floor Insulation
Polyurethane can also be used on floors indoors. Especially in humid areas such as bathrooms and kitchens, polyurethane waterproofing applied to floors prevents water from seeping into the floor. At the same time, dampness problems on the floors in the house are also solved.
9. Factory and Storage Areas
In factories, storage areas and production lines, water sealing requirements often arise. Polyurethane waterproofing acts as an effective barrier on concrete surfaces used in such areas. It also provides protection against chemical leaks that occur in industrial facilities.
10. Road and Bridge Structures
Polyurethane waterproofing is also used in road and bridge structures. Especially under bridges, road surfaces and reinforced concrete structures can be exposed to the negative effects of water. Polyurethane offers an excellent waterproofing solution for these structures and provides long-term durability.
Polyurethane waterproofing stands out with its superior performance in various application areas. It is a robust and reliable solution both in new construction projects and in protecting existing structures. Polyurethane provides excellent protection against water and at the same time, thanks to its flexible structure, it helps structures to be long-lasting.
