Hydrophilic water swellable bar,
-
Material: The bars are typically made from a hydrophilic (water-absorbing) material, often a synthetic rubber or polymer compound. These materials have the ability to absorb water and expand, creating a seal.
-
Design: The bars are often manufactured in various shapes and sizes, with some designed specifically for use in joints, construction joints, or expansion joints in concrete structures.
-
Installation: Hydrafilic water swellable bars are installed in the joints or areas where water ingress is a concern. During installation, care must be taken to ensure proper positioning and contact with the surrounding concrete.
-
Activation: The bars become activated when they come into contact with water. Once activated, they absorb the water and swell, forming a tight seal to prevent further water penetration.
-
Expansion Ratio: The ability of the bar to expand upon contact with water is a critical factor. This expansion ratio should be sufficient to create an effective seal and withstand the expected water pressure.
-
Adhesion to Concrete: The material should have good adhesion properties to bond with the concrete surfaces, ensuring a durable and long-lasting seal.
-
Compatibility: Hydrafilic water swellable bars should be compatible with the concrete and other materials used in the construction to avoid any chemical reactions that could compromise the effectiveness of the waterstop.
-
Long-Term Performance: These bars are designed for long-term performance and should be resistant to degradation over time, ensuring ongoing protection against water infiltration.

Here’s a professional, clear description of a Bentonite Hydrophilic Swell Water Stopper you can use for your catalog, website, or quotation:
💧 Bentonite Hydrophilic Swell Water Stopper✅ Description:
A Bentonite Hydrophilic Swell Water Stopper is a high-performance joint sealing strip made from natural sodium bentonite clay encapsulated in a durable rubber matrix. On contact with water, it swells up to 300% of its original volume, effectively blocking water pathways through concrete joints and preventing leakages.
✅ Key Features:
-
Self-injecting: Swells when in contact with water to fill cracks and voids.
-
Flexible & easily installed on irregular surfaces and around penetrations.
-
Provides a continuous waterproof barrier in concrete construction joints.
-
Repeated wet-dry cycles without significant loss of swelling capacity.
-
Resistant to chemicals typically found in groundwater.
✅ Technical Details:
| Property | Typical Value |
|---|---|
| Base Material | Bentonite & Rubber Compound |
| Swelling Capacity | Up to 300% |
| Standard Sizes | 20 x 25 mm / 20 x 30 mm / customized |
| Water Pressure Resistance | ≥ 7 bar |
| Service Temperature | -30°C to +60°C |
✅ Applications:
-
Construction cold joints in RCC basements, tunnels, water tanks
-
Retaining walls, sewage treatment plants
-
Pipe penetrations, manholes, culverts
-
Precast segment joints
✅ Advantages Over PVC Water Bar:

Polymer base Water swellable Bar
Minimum Order Quantity: 100 Meter
| Thickness | 10 mm |
| Size | 20x10mm |
| Material | Hydrofilic Polymner |
| Color | Red |
| Brand | SANDHYAFLEX |
| Hardness | 50 ot 60 Shore A |
Here’s a clear, professional description of a Polymer Base Water Swellable Bar, which you can use in your catalog, website, or datasheets:
Polymer Base Water Swellable BarDescription:
A Polymer Base Water Swellable Bar is a high-performance sealing strip made from hydrophilic polymers blended with synthetic rubber. It expands upon contact with water, effectively sealing construction joints, pipe penetrations, and concrete interfaces to prevent water ingress. Compared to bentonite-based bars, polymer swell bars offer more controlled swelling and better long-term performance.
Key Features:
-
Material: Hydrophilic polymer & synthetic rubber composite
-
Size: Commonly 20x25 mm, 10x20 mm, 5x20 mm (custom sizes available)
-
Swelling Capacity: Swells up to 200% to 400% of original volume in water
-
Water Pressure Resistance: Typically up to 6 bar (can vary by type)
-
Color: Usually red, blue, or black
-
Temperature Resistance: -30°C to +60°C
Applications:
✅ Construction cold joints & expansion joints
✅ Pipe penetrations through concrete
✅ Precast concrete segment joints
✅ Tunnels, basements, water tanks & swimming pools
✅ Retaining walls & culverts
Advantages:
✔ Controlled, uniform swelling — does not crack concrete like bentonite sometimes can
✔ Excellent chemical & biological resistance
✔ Easy to install with adhesives or nails
✔ Reactivates & reseals on subsequent wet-dry cycles
If you’d like, I can also prepare for you:
✅ A technical datasheet format
✅ A comparison vs bentonite swell bars
✅ A standard method statement for installation
