YN-B701 Powerful Self-Adhesive Polymer Modified Asphalt Waterproof Membrane
Product Overview
YN-B701 Self-Adhesive Polymer Modified Asphalt Waterproof Membrane is a self-adhesive waterproof membrane with a base material of self-adhesive polymer modified asphalt. It is designed for non-exposed use and can be either without a reinforcing base or reinforced with a polyester base for added strength.
Product Features
- Strong bonding force with cold self-adhesive construction, avoiding the instability of glue adhesion and fire hazards associated with heat welding.
- Excellent elongation properties, capable of resisting common deformations and cracks in the substrate.
- Long service life with excellent weather resistance, suitable for climate changes in both hot and cold regions. It can be installed using hot-melt method at temperatures as low as -10°C.
- Superior chemical resistance, weather resistance, and corrosion resistance.
- Capable of self-healing small punctures and damages.
- Compared to non-reinforced membranes, the reinforcing base turns the membrane into a waterproof layer, increasing tensile strength, durability, and impermeability.
- Simple construction process with low skill requirements, high efficiency, and rapid installation speed.
Precautions
- The construction base surface should be dry, clean, and free of visible water.
- The base surface must not have floating dust or debris, and local defects should be repaired and leveled.
- Apply a specialized base treatment agent evenly.
- The waterproof membrane should be laid flat and straight, with overlapping edges of no less than 100mm. Air underneath the membrane should be pressed out.
- After completing the waterproof layer of the membrane, it should be covered promptly.
- Internal corners should be rounded.
Scope of Application
- It is suitable for waterproofing, seepage prevention, and damp-proofing in roofing projects, underground projects, as well as open-cut subway and tunnel projects, and projects such as ponds, canals, bridges, and highways for various industrial and civil buildings.
- It is applicable to waterproofing projects on garage roof decks and concrete cushion planes of underground building floors, especially suitable for unstable structures or layers prone to shrinkage and cracking.
Storage and Transportation
- The waterproof membrane should be stored in a dry and well-ventilated environment to prevent exposure to sunlight, rain, and moisture.
- During transportation, the waterproof membrane should be placed upright and must not be laid on its side or cross-stacked under pressure.
- Under normal conditions, the storage period is one year from the date of production.
Construction Procedure
Base surface preparation → Application of base treatment agent → Local node treatment → Laying of waterproof membrane → Overlapping and sealing of seams → Ventilation treatment → Inspection and acceptance
