About Water Swellble Bar 25 x 20 mm

A Water Swellable Bar (25 x 20 mm) is a hydrophilic waterstop used to seal construction joints in concrete structures. It swells in contact with water to form a tight, compression-based seal, preventing water ingress through non-moving joints.

What is a Water Swellable Bar?

Its a rubber or bentonite-based sealing strip that increases in volume when exposed to water expanding to fill voids or gaps in concrete joints. The 25 x 20 mm size refers to the width (25 mm) and height (20 mm) of the strip.

Material Composition:

Hydrophilic Rubber (EPDM, Polyurethane, or Natural Rubber Blend)
Chemically engineered to expand multiple times its original volume when wet.
Bentonite-Based Swell Bars
Use natural clay minerals that expand when hydrated.
Often contains sodium bentonite or superabsorbent polymers (SAPs).

Typical Specifications:

Property	Value
Size	25 mm (W) x 20 mm (H)
Swell Ratio (by Volume)	150% 300% (depends on formulation)
Material Type	Hydrophilic Rubber / Bentonite
Water Pressure Resistance	Up to 7 bar (depends on product)
Installation Surface	Concrete-to-concrete construction joints
Elongation	200% 400% (for rubber types)

Advantages:

Self-sealing: Expands automatically in contact with water
Reliable in complex profiles: Conforms to irregular surfaces
Easy to install: No welding, special tools, or adhesive required
Reseals if cracked concrete allows water to re-enter
Chemical Resistance: Many grades resist salts and mild chemicals

Typical Applications:

Basement retaining walls
Tunnels and underground tanks
Precast concrete joints
Sewage treatment plants
Water tanks and swimming pools
Box culverts and pipe penetrations

Installation Guidelines:

Surface Preparation
- Clean and free from dust, grease, or loose particles.
Fixing
- Use adhesive, nails, or metal mesh to secure bar to the surface.
- Maintain continuous contact no gaps or breaks.
Concrete Placement
- Carefully pour concrete without displacing the swell bar.
- Avoid direct water contact before pouring concrete.
