Tiebid BAC self-adhesive waterproofing membrane is a self-adhesive waterproofing membrane manufactured with polyester fiber nonwoven fabric as the reinforcement, coated on both sides with self-adhesive rubber-modified asphalt compound and a release film or PE film. It can achieve full-surface bonding with clean and dry cementitious substrates, cement (sand) mortar, and various waterproof coatings, effectively preventing blistering and water channeling beneath the membrane.
Product Features
◎ Unique "self-healing" property: It can automatically heal minor punctures or damage under external forces, and has the ability to heal around nail penetrations or fine cracks, effectively ensuring the integrity of the waterproofing membrane system.
◎ Low substrate requirements, saving construction time: When applied using the wet-applied method, it can be installed on damp or even unleveled substrates without the need for a primer. This offers high construction flexibility, is unaffected by weather conditions, and provides a distinct advantage during rainy seasons, making it the most powerful "tool" for ensuring project schedules.
◎ Easy lapping and sealing: The material is inherently tacky, allowing for firm and secure self-lapping. Its surface can bond tightly with subsequently applied asphalt-based coatings, thereby resolving challenges such as pipe penetrations, terminations, and laps, and enabling seamless membrane installation.
◎ Excellent physical and mechanical properties: It offers strong resistance to external forces, reducing leakage caused by substrate deformation and cracking. It provides higher and stronger resistance to water pressure, puncture, fatigue, and tearing.
◎ Good high-temperature resistance and low-temperature flexibility: It adapts to the requirements of different regions and climates, offering a wide range of applications.
◎ Safe and environmentally friendly: The installation process requires no organic solvents or fuels, avoiding environmental pollution, eliminating fire hazards, and conserving resources.
Scope of Application
Suitable for waterproofing and seepage control projects in basements, roofs, and other areas of industrial and civil buildings.
