About Swellable water bar

A Swellable Water Baralso called a hydrophilic waterstopis a flexible sealing material used in concrete construction joints to prevent water ingress. It's especially useful in underground structures, tunnels, basements, retaining walls, and water tanks.


What Is a Swellable Water Bar?

A swellable water bar is typically made from sodium bentonite or hydrophilic polymers that expand when in contact with water. When placed in a joint or around penetrations in concrete, the bar swells to fill the gap, creating a watertight seal.


Key Features:

Feature Details
Material Sodium Bentonite Clay, Hydrophilic Rubber (e.g. polyurethane, EPDM-based)
Swelling Ratio Can swell up to 300500% of original volume
Dimensions Common sizes: 20x25 mm, 25x25 mm, 10x20 mm, etc.
Installation Glued or nailed into place before second concrete pour
Water Pressure Resistance Up to 510 bar (varies by product)

Applications:

  • Cold joints between concrete pours

  • Pipe penetrations

  • Precast segments

  • Box culverts

  • Basement slabs and walls

  • Tunnels and water retaining structures


Advantages:

  • Self-sealing upon water contact

  • Conforms to irregular surfaces

  • Easy to install (can be glued or nailed)

  • Provides active sealing (expands to fill gaps)

  • Works in both horizontal and vertical joints


Installation Tips:

  • Apply on dry concrete only premature contact with water may cause it to swell too early.

  • Protect during concrete pour to prevent displacement.

  • For high water pressures, use with PVC or metal waterstops as a secondary barrier.

  • Some products come with a delayed swell time to avoid early expansion.


Types of Swellable Water Bars:

Type Description
Bentonite-Based Swells naturally with water exposure; cost-effective
Polymeric (Hydrophilic Rubber) More controlled and repeatable swelling; suitable for higher-performance applications
Combination Types Blend of bentonite and rubber for balanced performance

Example Products (brand types vary by region):

  • SikaSwell (Sika)

  • Hydrotite (Adeka)

  • GCP Swellseal

  • Fosroc Supercast SW

Versatile Sealing Solution

The Swellable Water Bar is engineered for a wide array of construction and water-proofing uses. It forms an effective barrier against water ingress at construction joints, expansion joints, and penetrations, ensuring integrity in both above and below ground structures.


Quality Material and Design

Manufactured from natural rubber with medium hardness and a natural finish, this product combines strength and flexibility. Its 6 mm thickness and 10 mm x 20 mm size make it adaptable for diverse installation requirements, while the red color ensures clear visibility during application.

FAQs of Swellable water bar:


Q: How does the Swellable Water Bar function during installation?

A: The Swellable Water Bar is installed in construction joints where it expands upon contact with water, creating a tight seal that prevents leakage. Its swellable properties make it suitable for structures exposed to high moisture or water pressure.

Q: What benefits does the natural rubber material provide?

A: Natural rubber gives the water bar excellent flexibility, elasticity, and durability. It ensures a long lifespan, resists wear and tear, and maintains integrity under varying environmental conditions.

Q: When should I use a Swellable Water Bar in construction?

A: You should use a Swellable Water Bar whenever theres a risk of water ingress at concrete joints, around penetrations, or in retaining walls. It is especially useful in basements, tunnels, water tanks, and other structures requiring watertight seals.

Q: Where can this product be sourced in India?

A: The Swellable Water Bar is widely available across India and can be obtained through licensed dealers, fabricators, manufacturers, producers, retailers, suppliers, traders, and wholesalers specializing in construction materials.

Q: What is the process for installing the Swellable Water Bar?

A: Installation involves placing the water bar in the middle of concrete joints or around pipe penetrations before pouring concrete. Ensure it is properly positioned for uniform expansion when exposed to water.

Q: What is the recommended size and thickness for typical applications?

A: For most construction needs, the recommended size is 10 mm x 20 mm with a thickness of 6 mm, which delivers optimal sealing performance and versatility in various joint configurations.
