1. Strong cohesive force, self-adhesive construction; safe and quick;
2. Excellent elongation, self-healing smaller puncture damage;
3. Unique separation of the upper and lower surface separation paper to ensure that the double-sided tape is not contaminated;
4. Coil lap three insurance: adhesive, adhesive film, external sealing paste;
5. Self-locking water performance is excellent, the membrane breakage leakage limited to local local, to avoid the overall failure of the waterproof layer.
1. Pre-installed waterproofing membrane for subway tunnels and other underground works of the floor and side wall waterproof, can also be used for other pre-2. anti-stick construction method of the site; web directly with the post-pouring structure of concrete mix The
3. Wet shop waterproofing membrane for non-exposed roof, underground waterproofing works, as well as digging subway, tunnels, pools, canals and other projects waterproof, especially for unauthorized use of open fire works.
Plastic tape is packed in rolls
1. Different varieties, labels, specifications and grades of the coil should be classified stacking;
2. Avoid rain, exposure, attention to ventilation;
3. Storage temperature is not higher than 45 ℃, P class of building materials flat, PY type legislation storage.

According to the engineering structure, engineering category, engineering design, the use of different requirements such as the use of wet shop or pre-shop construction methods.
1, the coil pre-shop: the amount of good product cutting, the coil of the self-adhesive layer of paper facing the structure layer, the other side towards the grass, pre-laying in the cushion, protective wall, underground wall or row of piles. (Submerged tunnel with a geotextile surface material of the polymer membrane directly hung in the pre-fixed hook)
2, Coil seams: Coil joints using cold self-adhesive way, tear off the seam self-adhesive edge of the isolation tape can be directly paste to form a complete sealed waterproof system.
3, the film anti-stick: tear off the separation of paper, pouring structural concrete, the coil can flow with the concrete cross-linked to form a strong adhesive force. So that the membrane will be bonded to the concrete building structure, thus forming a waterproof membrane and the structure of rigid and flexible without gaps.
4, if you want to banding steel, peeled off the paper can be directly tied to the gap, no longer need to pour the mortar for the waterproof concrete mortar to do the protective layer.
The same time as the above-
Wet shop method
1, grass-roots treatment: clean up the grass-roots surface, the grass-roots can be wet, but can not have water. If the grassroots dry water to be wet.
2, the preparation of cement paste: in the cement (not less than 32.5R grade generic silicon cement) which directly add water, cement: water = 1: 0.3 ~ 0.4 (weight ratio, according to the actual situation reasonable adjustment), stir with electric mixer 1 ~ 2min, mix well for 5 ~ 8min.
3, coil paste: with a trowel or scraper will be mixed with a good mix of cement paste in the grass on the base layer, while scraping the edge of the polymer composite self-adhesive waterproof sheet paved in the above, and exhaust pressure real.
4, seam paste: coil joints with cold self-adhesive way. Adjacent short edge seams should be staggered more than 1m; long side seam construction, tear off the seam self-adhesive edge of the isolation zone, aligned paste mark line directly paste; and then use a special seal paste will strengthen the sealed handle The
