PN Unvulcanization Waterstop Has Good Impermeability, Anti-Corrosion
PUW-1: Black PN unvulcanization waterstop.
PN unvulcanization waterstop is a kind of water swelling waterstop. It is also called putty type waterstop. PN unvulcanization waterstop is new type of building waterproof material that is made of polymer, inorganic water swelling materials, rubber and additives being extrusion by machine without vulcanization process. This kind waterstop will produce 2-3 times the expansion deformation after soaking. So it can fill the construction joints to prevent leakage thoroughly. And its hydrophilic swelling has not lost after repeated long-term expansion. Our products use non-toxic and pollution-free materials. It will do not harm to people and environment. In addition, our PN unvulcanization waterstop with good corrosion resistance can be used in many underground constructions without damaged.
- Width:4, 5, 7, 10, 15, 20, 30, 40, 50 mm.
- Height: 10, 20, 30, 25, 40, 50, 60 mm.
- Color: black, red and other colors also can be customized.
Note: Other specifications also can be customized.
|Volumn Expansion Rate||150||220||300|
|Flow at High Temperature(80°C × 5 h)||no flow||no flow||no flow|

PN unvulcanization waterstop can be packed as rolls. And the rolls can be backed in the cartons. We also can pack as your request.
PUW-2: PN unvulcanization waterstop packed in carton.
PUW-3: Many cartons of PN unvulcanization waterstop.
- It will swell after soaking, better impermeability.

PUW-4: The thickness of PN unvulcanization waterstop before soaking.
PUW-5: PN unvulcanization waterstop swells after soaking.
PUW-6: The PN unvulcanization waterstop has excellent expansion performance.
- Swimming pool.
- Sewage treatment works.
- Underground garage.
- Storage tank.
- Power plant cooling tower.
- Wall seam.
- The construction joints, expansion joints, cracks of concrete works.
- The storage and transportation of waterstop should avoid moisture and extrusion deformation.
- Before the next concrete pouring, the construction joints that have appeared all should install the waterstop.
- The construction joints and after pouring seam that need to fix waterstop should keep dry. And you should clear the scum, dust and debris on interface.
- After determining the installation site of waterstop, we should apply a thin layer of adhesive on the interface where the waterstop is to be installed and on the bottom of the waterstop. And we should paste after a period of volatility. We also can fix the waterstop on the mounting area with high-strength anchor.
- In case of concrete interface is damp or uneven, adhesive paste fixed is not strong, we can further strengthen the fixed with strong nail depending on the specific situation. In short, the PN unvulcanization waterstop must be in close contact with the concrete interface and fix closely to prevent PN unvulcanization waterstop out of the interface and lose impermeability.
- After installing the waterstop, it should be poured with concrete. The thickness ＞50 mm.
- The connection of waterstop should be connected in overlapping methods. It should be fixed with high-strength nails after pasting. The installation path forms a closed loop along the construction seams without break points.
- Before pouring the next concrete, the PN unvulcanization waterstop should avoid being soaked in water and other submerged water.
- When pouring concrete, the vibrator should avoid to touch PN unvulcanization waterstop.
