Product Description

A Water Swellable Bar 25x25mm is a high-performance hydrophilic sealing strip made from bentonite clay or rubber-based swellable materials designed to prevent water ingress in concrete joints, pipe penetrations, and other vulnerable areas in construction. The 25x25mm size indicates a larger cross-section, ideal for sealing wider or deeper joints and handling higher water pressures.


Product Overview Water Swellable Bar 25x25mm

Dimensions:

  • Width: 25mm

  • Height/Thickness: 25mm

  • This larger size provides greater swelling capacity and stronger water resistance, ideal for critical sealing zones.


Key Properties:

  1. Swelling Capability:

    • Swells up to 300%400% of its dry volume when exposed to water.

    • Forms a tight, pressure-resistant seal inside joints and cracks.

  2. Composition Options:

    • Bentonite-Based: Natural clay that swells on water contact.

    • Rubber-Based (Hydrophilic Rubber): Offers elasticity and chemical resistance in addition to swelling.

  3. Self-Sealing:

    • Automatically activates on contact with waterno primer or external treatment required.

  4. Flexible & Durable:

    • Accommodates minor structural movements without losing sealing performance.

  5. Chemical Resistance:

    • Resistant to a wide range of chemicals found in groundwater or construction environments.


Applications:

  • Construction Joints in concrete (vertical or horizontal)

  • Basement Walls & Foundations

  • Tunnels, Dams, Reservoirs

  • Water Tanks & Sewage Treatment Plants

  • Pipe and Duct Penetrations through concrete

  • Precast Elements joints and lift shafts


Advantages:

  • High Swell Volume: Fills voids efficiently even in large or uneven joints.

  • No Maintenance Required

  • Simple Installation

  • Cost-Effective Waterproofing

  • Long Service Life

  • Environmentally Friendly (especially bentonite versions)


Installation Tips:

  1. Surface Preparation:

    • Clean the concrete surface of dust, oil, and loose particles before placing the bar.

  2. Fixing Method:

    • Use nails, adhesive glue, or mesh wire to secure the bar to the concrete surface or formwork.

    • Ensure full contact with the joint surface.

  3. Joint Overlaps:

    • Overlap ends by at least 50mm or use a butt joint with adhesive to prevent water bypassing.

  4. Concrete Cover:

    • Ensure a minimum 50mm concrete cover around the bar to allow for safe expansion and containment.

  5. Avoid Premature Swelling:

    • Protect bars from water exposure before concrete pouring (cover with plastic if needed).
