Generally, PBC-328 and modified bitumen waterproof membrane together form composite waterproof layer.
Where to use
PBC-328 is suitable for undulating area, large stress area, and the area which may happen shape change or always change, particularly suitable for the project which is not allowed flame construction, mechanical application project and cold application project.
PBC-328 is suitable for concrete roofing, steel roofing, underground, pond and tunnels waterproof constructions.
Excellent adaptability for the structural deformation
PBC-328 can adapted to structural deformation, when the basement cracking and waterproof layer stretching, PBC-328 can absorb stress, close micro-cracks of the basement level, to ensure the entire waterproof system maintain integrity long-term.
Excellent self-healing ability
When PBC-328 waterproof layer is punctured by external force, the broken point would not extend, the bottom of waterproof layer would not happen channeling water, and the creep properties of PBC-328 enables self-healing after the destruction of the material, which improve waterproof layer reliability, reduce the cost of repair and maintenance.
Excellent aging resistance, low temperature flexibility, chemical corrosion resistance.
Excellent adhesion performance
PBC-328 can bond with different basement surface, excellent adhesion performance.
Feeding in and pumping out continuously, PBC-328 can be applied to the specified thickness once, construction speed is around 115m2/hour.
Safety and environmental protection
PBC-328 solid content is over 99%, non-toxic, solvent-free, no open flame when application, safety and environmental friendly.
