Modified bitumen waterproofing membranes are applied through a process that involves heating the membrane to activate its adhesive properties. The surface is prepared by cleaning and priming, ensuring proper adhesion. The membrane is then rolled out and adhered to the substrate, either by torching, self-adhesive methods, or cold adhesive application. Overlapping seams are sealed to create a continuous waterproof barrier. This method enhances durability and flexibility, making it suitable for various roofing and waterproofing applications.
