APP Modified Bitumen Technology: Formulated with Atactic Polypropylene to provide superior heat resistance and high-temperature stability, ensuring the membrane does not flow even in intense climates.
Precision 1.5mm Thickness: Offers a consistent and reliable protective layer that balances flexibility with high tensile strength for effective crack-bridging in structural slabs.
Seamless Heat-Welded Joints: Applied via torch-on or heat-welding techniques to create perfectly fused, monolithic joints that eliminate the risk of water seepage at the seams.
Polished Surface Treatment: Features a refined black polished finish that enhances the ease of application and provides a clean substrate for subsequent protection layers or finishes.
Broad Structural Application: Ideal for various waterproofing requirements, including flat and sloped roofs, terraces, balconies, and below-ground structural tanking.
