About SWELLABLE BAR

91 000 74051 A Swellable Water Bar is a flexible hydrophilic strip used for waterproofing construction joints and cold joints in concrete structures. When it comes into contact with water, it swells up to many times its original volume, blocking water passage and sealing the joint effectively.

It is an ideal alternative to conventional PVC water stops for difficult placements, vertical joints, and complex shapes.

Key Features & Benefits

Hydrophilic swelling action Expands up to 200300% on contact with water, sealing gaps.

Easy installation Can be nailed, stapled, or fixed with adhesive in construction joints.

Excellent water sealing Prevents leakage through joints and honeycombs.

Durable & chemical resistant Resists saline water, mild acids & alkalis.

Flexible & adaptable Suitable for irregular profiles, penetrations, and difficult joint shapes.

Cost effective Replaces large PVC water stops in many applications.

Areas of Application

Water tanks, underground sumps

Sewage treatment plants, STPs & ETPs

Tunnels & metro structures

Basements, raft slabs, retaining walls

Dams, canals, culverts, bridges

Precast segments & segmental linings

Pipe penetrations & concrete joints

Method of Application

Surface Preparation: Clean joint surface free of dust, oil, and laitance.

Fixing: Place water bar in center of joint using nails, adhesive, or holder.

Overlap: Ensure overlaps are minimum 50 mm, press firmly to avoid gaps.

Concrete Placement: Pour concrete carefully without displacing the water bar.

Curing: Allow concrete to set; upon water exposure, the strip swells to seal joints.

FAQ (Questions & Answers)

Q1. What is a swellable water bar used for?

It is used in construction joints (horizontal & vertical) to prevent water seepage.

Q2. How does it work?

It swells on contact with water, blocking water pathways through joints.

Q3. Can it be used instead of PVC water stops?

Yes. Especially suitable where PVC water stops are difficult to fix, like vertical joints, small widths, and repair jobs.

Q4. What sizes are available?

Common sizes are 25 10 mm, 20 15 mm, 25 20 mm, etc. Custom sizes are also available.

Q5. What is the swelling capacity?

Typically 200300% of its volume depending on grade and water quality.

Q6. How to install it?

It is fixed with nails, adhesives, or concrete nails in the joint before pouring concrete.

Q7. What is the price?

Average market price is around 200 350 per meter depending on size, brand, and quality.

Superior Water-Sealing Technology

The Swellable Bar is specifically designed to provide robust protection for construction joints against water ingress. Upon contact with water, it swells up to 300%, ensuring tight sealing even in the most demanding environments. This advanced swelling capacity gives engineers and contractors peace of mind when working in areas prone to water exposure.

Outstanding Performance and Durability

With a wide operating temperature range from -30C to +80C and resistance to common construction chemicals, the Swellable Bar is suitable for diverse job sites and climates. Its strong tensile strength and elongation ensure long-term performance, making it a reliable solution for new builds and repairs.

Easy Application and Versatile Use

Manufactured in a convenient 8 x 20 mm size and bright red for visibility, the Swellable Bar is easy to install in various construction projects. It is supplied across India through trusted distributors, service providers, and suppliers, ensuring ready availability for your sealing needs.

FAQ's of SWELLABLE BAR:

Q: How does the Swellable Bar effectively seal construction joints against water ingress?

A: The Swellable Bar is made from a special rubber polymer that expands up to 300% when it comes into contact with water. This swelling action fills gaps and conforms tightly to joint surfaces, providing a highly effective barrier against water intrusion in concrete structures.

Q: What installation process should be followed for the Swellable Bar?

A: To install, position the Swellable Bar firmly within the joint or groove before pouring concrete. Ensure that the surface is clean and the bar fits snugly. Once concrete is poured and the structure is exposed to moisture, the bar will swell and create a watertight seal.

Q: Where can the Swellable Bar be used most effectively?

A: The Swellable Bar is suitable for sealing construction joints in basements, tunnels, water tanks, culverts, and retaining walls. Its temperature and chemical resistance allow it to perform reliably in a variety of subterranean and above-ground applications.

Q: When is the ideal time to install the Swellable Bar during the construction process?

A: The Swellable Bar should be installed before concrete pouring, during the initial construction stage of the joint. Installing it beforehand ensures proper bonding and swelling action once the structure is exposed to water.

Q: What are the main benefits of choosing this Swellable Bar over traditional sealing methods?

A: This Swellable Bar offers superior adaptability, high swelling capacity, excellent chemical and temperature resistance, and simple installation. These properties contribute to extended durability, effective sealing, and reduced maintenance compared to many conventional joint sealants.

Q: How should the Swellable Bar be stored before use?

A: For optimal performance, store the Swellable Bar in a cool, dry place away from direct sunlight. Proper storage helps to maintain the bar's swelling and mechanical properties until installation.
