The BXI SBS Modified Bitumen Waterproofing Membrane Roll is a professional-grade torch-on asphalt material designed for homeowners, contractors, and DIY enthusiasts tackling waterproofing challenges. Measuring 13 inches by 8.2 feet with 1/8-inch thickness, it covers 8.86 square feet and suits roofs, foundations, decks, basements, bathrooms, pools, and other wet areas as a base, middle, or top layer in leak repair projects.
Standout features include its self-healing capability, where the material flows to seal minor punctures or damages, and exceptional all-weather performance from -20°C upward without cracking or losing flexibility. The SBS polymer-modified bitumen penetrates cracks deeply upon torch heating, creating powerful adhesion, while resisting tears, chemicals, UV radiation, and aging for reliable long-term outdoor use. Its textured surface promotes even melting and easy application on curved or irregular surfaces.
Build quality shines with a dense, high-density formula (0.77 lbs/sqft) in a crease-free roll that's simple to cut and install solo. Options for torch application or waterproof glue add versatility, though the asphalt odor is noticeable. At 6.83 pounds, it's manageable but requires proper safety gear for heating.
Potential drawbacks include the need for a torch or adhesive, which demands some skill, and the inherent odor. Overall, this membrane delivers robust, flexible waterproofing value for demanding sites, earning strong recommendation for anyone seeking durable, self-repairing protection against leaks and water intrusion.
