Waterproofing is essential in areas with humid and rainy climates. After all, buildings that are improperly protected may experience water seepage, structural damage, and expensive repairs. Various waterproofing options now exist, but the type of building, the material, and the amount of moisture exposure still influence which approach will be best. Engaging a waterproofing specialist helps assess a property and recommend the most suitable method.
Discover the typical methods of waterproofing in Singapore and learn which suits your needs.
7 Waterproofing Methods Used in Singapore
1. Liquid-Applied Membrane Waterproofing
Liquid-applied membranes are widely used for waterproofing due to their flexibility and ease of application. These coatings are applied in liquid form and cured to create a seamless, watertight barrier. They can be used on roofs, balconies, and wet areas. The main advantage is that they can conform to irregular surfaces and provide a uniform protective layer. However, the effectiveness depends on the thickness and quality of the application. Professional waterproofing contractors ensure that the right materials and application techniques are used to maximise durability.
2. Cementitious Waterproofing
Cementitious waterproofing is commonly used for internal areas not exposed to sunlight and weathering. It is a mix of cement-based materials and waterproofing additives applied as a slurry or coating. This method is preferred for basements, toilets, and water tanks. The benefits include ease of application, affordability, and compatibility with concrete surfaces. However, it is rigid and does not accommodate structural movement, making it less suitable for areas prone to cracks. A waterproofing specialist can reinforce it with additional coatings or membranes for improved performance.
3. Polyurethane Waterproofing
Polyurethane-based waterproofing is highly effective for areas exposed to constant moisture and movement, such as balconies and terraces. It provides strong adhesion to different surfaces and offers excellent flexibility, which helps in preventing cracks. This method is resistant to chemical exposure and UV rays, making it a preferred choice for waterproofing buildings. Despite its advantages, polyurethane is sensitive to moisture during curing, requiring experienced contractors for proper application. If applied incorrectly, it may result in bubbling or poor adhesion, leading to water infiltration.
4. Bituminous Membrane Waterproofing
Bituminous membranes are used for roof leakage repair in Singapore due to their high water resistance and durability. This waterproofing method consists of sheets made from bitumen-based materials, reinforced with polyester or fibreglass. These sheets are either torch-applied or self-adhesive and are commonly used on flat roofs and basement walls. The key advantages include long lifespan, resistance to UV rays, and excellent waterproofing capabilities. However, proper installation is critical, as poor adhesion can lead to water seepage. Regular maintenance is required to ensure continued protection against leaks.
5. Acrylic Waterproofing Coating
Acrylic coatings are used as a cost-effective and environmentally friendly waterproofing solution. They are applied in liquid form and cured into a seamless, elastomeric membrane. This method is suitable for roofs, facades, and balconies. Acrylic coatings offer UV resistance and flexibility, making them efficient for exterior applications. However, they may require multiple coats and regular maintenance to ensure long-term performance. A waterproofing specialist can recommend high-quality acrylic products to enhance durability and effectiveness.
6. Torch-On Membrane Waterproofing
Torch-on membranes are made from modified bitumen and are applied using heat. This method is commonly used for roof leakage repair, especially for flat or low-slope roofs. It provides a thick, durable layer that prevents water infiltration. Torch-on membranes resist extreme weather conditions, making them ideal for the region’s climate. The downside is that installation requires skilled professionals due to the use of open flames. Improper application can result in weak adhesion and water seepage. Regular inspections and maintenance are necessary to prolong its lifespan.
7. Crystalline Waterproofing
Crystalline waterproofing is used for concrete structures to enhance their water resistance. It works by penetrating the concrete and forming crystals that block water pathways. This method is ideal for basements, underground structures, and water tanks. It provides long-term waterproofing as the crystals continue to grow in the presence of water, sealing cracks over time. Unlike surface coatings, crystalline waterproofing integrates into the structure, making it highly durable. However, it is unfit for flexible structures as it does not accommodate movement. Waterproofing contractors use this method with other waterproofing techniques for added protection.
Choosing the Right Waterproofing Method
Selecting the appropriate waterproofing method depends on the location, material, and specific water exposure risks. A waterproofing specialist can thoroughly assess and recommend the most effective solution. Factors such as durability, maintenance requirements, and budget should also be considered. Remember, waterproofing is a critical investment that prevents costly repairs and extends the building’s lifespan.
Conclusion
The city-state’s climate makes waterproofing essential for all types of buildings. Fortunately, there are numerous waterproofing techniques available, each with unique advantages and disadvantages. Whether it is bituminous sheets, cementitious coatings, or liquid-applied membranes, choosing the appropriate method guarantees long-term protection against leaks. Remember, fixing roof leaks can be expensive If waterproofing is neglected, therefore, taking preventative action is essential. Lastly, speaking with a knowledgeable waterproofing specialist in Singapore guarantees that the best products and methods are applied for optimum results.
