        1, good waterproof, self adhesive layer and surface film has very good waterproof function
.
        2,It has unique self-healing, and can self heal after puncture damage
.
        3, It has very strong grass-roots adhesion, effectively prevent the phenomenon of water channeling
.
        4, the integrity is good, the sheet  has a very good corrosion resistance, long service life; the construction is simple, pressure sensitive adhesive, lasting stability.
        5, double sided self-adhesive membrane can be used as waterproof layer, also can form multiple waterproof system with a variety of composites.
