01
Lower temperature sensitivity
The coil's self-adhesive layer has low temperature sensitivity, which can make the coil maintain a good bonding effect with the grassroots in the ambient temperature range of -40℃~120℃, and can be suitable for use in different climate regions.
02
Lighter and softer material
The coil has excellent flexibility and can be applied to a variety of complex substrate construction
03
Skin-type waterproof
Excellent bonding performance during full-adhesive construction, can be fully bonded with the grassroots, high bonding strength, good water locking effect
04
Cold Construction
No open flame, energy saving and environmental protection
05
Good corrosion resistance
Free from microbial attack, anti-mold

Construction Method

Pre-paving method


The coil is laid empty on the grass-roots level, and the material is lap-treated and tied directly to the reinforcement and poured concrete. In the concrete solidification, and coil 100% solid bonding, and the formation of a dense waterproof layer.
