Product Description

Product Description

Bentonite is a swellable clay waterproofing compound that is glued or nailed in strips into construction joints. Known as a hydrophilic waterstop system, bentonite expands up to sixteen times its dry volume when it comes into contact with water, forming a compression seal in concrete joints. Bentonite's ability to swell enables it to fill small cracks and voids in concrete, preventing the ingress of water around joints. And since clay is a natural material, bentonite is a popular waterstop choice for potable water applications.

How to use vulcanized expansion ?

1) It is necessary to paste the construction joint for fixing the vulcanized product type expansion  The interface of the post pouring joint shall be kept dry and flat. The scum, dust and other objects on the interface shall be cleaned before the construction of 

2) After the installation position of vulcanized expansion Water Stop Strip is determined, apply a thin layer of adhesive on the interface where the  needs to be placed and the bottom surface of the Water Stop Strip, and paste it after the mucus volatilizes for a period of time, or fix the Water Stop Strip at the installation position with anchor nails.
Features & benefits:

• High watertight properties - once exposed to water, PZ waterstop will expand one to five times to fill all irregular surfaces, holes and spacing of surrounding concrete. Meanwhile, if the construction joints are displaced which will result in oversized gaps beyond elastic range of waterstops, traditional waterstop will lose its effect of water-proofing, but our PZ waterstop still performs great by continual swelling.
• Much stronger advantages of cross-linked chemical structure at the atomic level.
• Smaller size but uncompromising water swelling property.
• Eliminate elastic fatigue caused by excessive compression.
• Excellent water resistance, chemical resistance and anti-aging property.
• Easy and quick to install.
• 3) If the concrete interface is wet or uneven and the adhesive is not fixed firmly, the water stop bar can be further fixed with anchor according to the specific situation. In short, the vulcanized Water Stop Strip must be in close contact with the concrete to prevent it from being separated from the expansion and fixation interface.

Applications:

• Pipe penetration.
• Water reservoirs.
• Settling pond.
• Deformation and concrete construction joints of civil engineering.
• Water conservancy and hydro-power projects, etc.

4)Water swelling  is a unique new rubber product, which is the general name of putty Water Stop Strip and product Water Stop Strip with water swelling performance. The rubber Water Stop Strip produces 2-3 times expansion deformation after encountering water, and fills all irregular surfaces, cavities and gaps of the joint. The Water Stop Strip produces huge contact pressure at the same time to completely prevent leakage.

Water swelling strip is the general name of putty type water stop strip and product type water stop strip with water swelling performance.

Water swelling rubber is a unique new rubber product. The Water Stop Strip not only has the performance of general rubber products, but also has the performance of self expansion in case of water. The  is a new waterproof material. The Water Stop Strip and waterproof effect are more reliable than general rubber.
 

Our Advantages

 

Water swelling rubber has more characteristics and advantages than ordinary rubber. The Water Stop Strip produces 2-3 times expansion deformation after encountering water, fills all irregular surfaces, cavities and gaps of the joint, and generates huge contact pressure to completely prevent leakage.

 

Product Parameters

PN Type Bentonite Waterstop Strip
PN type is one type hydrophilic watertight product made of rubber and other additives, which make it expansible with physical properties without vulcanization molding process, which is the only process different from PZ type, normally choose this type at <350% expansion rate that reducing production cost on base of quality.

PZ Type Waterstop Strip

PZ type is one type hydrophilic watertight product made of rubber and other additives, which make it expansible with physical properties by through vulcanization molding, but different from general extensibility characteristics and elastic seal water function.It can be water swelling with water with affection of it to make it more reliable than ordinary waterproof materials, normally choose this at >330% expansion rate.
