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.

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.

Applications:

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

 

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.

1	Expansion rate/% ≥	150	220	300
2	Flow at High Temperature(80ºC×5 h)	No flow	No flow	No flow
3	Low temperature test (-20ºC×5 h)	No crack	No crack	No crack
4	Peel Strength	0.05 MPa
5	Shear Strength	1.0 MPa
6	Hydrostatic Pressure	1.2 MPa

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.

Other bentonite waterstops for specific applications are also available in our company as shown follow:

Bentonite waterstop with expanded metal

Bentonite waterstop with expanded metal is a new type water sealing product. The added expanded steel mesh (or nylon mesh as your request) effectively enhances the tensile strength of the waterstop and improves the overall construction quality.

Bentonite waterstop with grouting pipe

The perfect match of bentonite waterstops and grouting pipes extremely improve the performance of the water-proofing capability. Once the leakage of water occurs, you can plug the crack through pouring chemical grout into the pipe, instead of slotting and drilling a hole on the construction surface.

Sizes:

• Width: 10 mm, 15 mm, 20 mm, 30 mm, 40 mm, 50 mm.
