Seamless, lightweight and flexible liquid waterproofing systems


Amid the pressures and complexities of construction, life never stops. Nor should your roofing project. That’s where a little fluid thinking goes a long way. Our liquid waterproofing systems provide long-lasting durability and can be used across new builds and refurbishment, so you're sure to find the right system that is right for your project.

Our range of liquid roofing systems can be split into two categories: cold applied systems that do not require the application of heat during their installation and our hot melt systems which require heat via a bitumen boiler.

Combining unparalleled flexibility with fast installation and proven performance, Sealoflex gives you a practical, efficient and cost effective waterproofing solution.
