Waterproofing is an essential aspect of building construction and maintenance. Water damage leads to costly repairs and even structural failure over time. There are several types of waterproofing methods and materials available. Understanding the main differences between waterproofing materials will help you to find the best product for your project. The two popular liquid applied elastomeric waterproof coatings will be discuss bellow:
Modified Bitumen Rubber (Liquid Rubber® HB-S) vs. Elastomeric acrylic Waterproofing (Liquid Rubber® Rubber RoofSeal)
Modified Bitumen Rubber is ideal for areas requiring water retention or water ingress prevention, such as slabs, foundations, and reservoirs. This thick coating dries into a seamless, highly flexible membrane, making it perfect for areas with ponding water. It has good keying qualities making it ideal to plaster over or tile over thus creating a sandwiched waterproof interlayer.
Elastomeric acrylic Waterproofing excels in free-draining areas like sloped roofs or walls. It offers colour selection, making it a popular choice for visible areas where aesthetics matter. However, acrylic rubber-modified coatings may not perform well in areas with ponding water.
Durability and Flexibility
Since 2009 we constantly innovate with research and development to ensure optimal balance between performance, quality, and cost. Our Waterproofing and corrosion protection coatings are enhanced with rubbers and polymers to provide superior elasticity and UV durability. This modification allows the coating to flex with the structure, preventing cracks and ensuring long-lasting protection.
Easy, Cost-Effective Application
A key advantage of our waterproof coatings is the ease of application, reducing labour costs and making it accessible to both professionals and DIY users. The coatings can be applied by brush, roller or airless spray system.
Seamless Membrane with Buildable Thickness
Over time maintenance coats can be added to increase the thickness, ensuring continued effectiveness. This buildable approach allows for a more robust and adaptable waterproofing solution and extends the service life.
HB-Sealant for Rehabilitating Old Torch-Down Systems
In addition to new applications, our modified bitumen rubber is ideal for rehabilitating old torch-down systems. Its ability to adhere to existing torch-on bitumen felt membranes rejuvenates and extends the life of aging bitumen felt waterproofing, providing a cost-effective solution for renovation projects.
HB-Sealant Resists Environmental Challenges
Our modified bitumen rubber also offers excellent resistance to water, chemicals, salts, and sulphates, making it effective in harsh environments like box gutters where bird excrement can cause corrosive damage. This resistance ensures the waterproofing layer remains intact and effective, even in the most challenging conditions.
Conclusion
When it comes to waterproofing, choosing between modified bitumen rubber and elastomeric acrylic waterproofing depends on the specific needs of your project. Modified bitumen rubber is the superior choice for areas requiring robust protection against ponding water and water ingress, while elastomeric acrylic modified coatings are better suited for free-draining areas where colour selection is a priority. For long-lasting, cost-effective waterproofing that stands up to environmental challenges, Our Liquid Rubber® coating systems provide a seamless, flexible, and durable barrier that adapts to your needs. Whether for new construction or rehabilitating old systems, it’s the reliable choice for ensuring the integrity of your structures.
