Heres a detailed overview of a Water Swellable Bar with the dimensions 25 x 20 mm, commonly used in construction and sealing applications to prevent water penetration.
A Water Swellable Bar is a water-activated sealing product designed to expand when in contact with water. It is commonly used in construction, especially in underground structures, tunnels, and basements, to seal joints and prevent water ingress. The bar is made of a special material that swells upon hydration, forming an effective barrier to water penetration.
Water Activated: Expands when exposed to water, creating a tight seal against moisture.
Durable and Flexible: Provides long-lasting waterproofing without cracking or losing its sealing properties over time.
Non-toxic and Safe: Suitable for use in construction projects where safety and environmental considerations are crucial.
Easy to Install: Typically placed in joints, between concrete sections, or around pipes to prevent water seepage.
Compact Size: The 25 x 20 mm size is perfect for narrow joints and smaller gaps that require effective sealing.
| Specification | Details |
|---|---|
| Dimensions | 25 mm (width) x 20 mm (height) |
| Material | Special blend of hydrophilic polymers |
| Color | Usually black or grey, though custom colors are available |
| Water Expansion | Expands up to 300% of its original size upon contact with water |
| Temperature Range | -10C to +50C |
| Density | High-density for durable sealing |
| Curing Time | Swells within minutes of water exposure |
| Pressure Resistance | Effective under low to medium water pressure (depends on installation) |
Joint Sealing: Used in construction joints, expansion joints, and precast concrete panels to prevent water ingress.
Underground Structures: Ideal for waterproofing foundations, basements, tunnels, and other below-ground structures.
Pipeline Sealing: Used around pipes that pass through concrete to create water-tight seals.
Concrete Constructions: Applied in areas that are prone to water contact like dam constructions, retaining walls, and swimming pools.
Waterproofing: Effectively blocks water ingress in construction and underground applications.
Durability: The bar remains functional even under extreme pressure or during long periods of water exposure.
Cost-Effective: Reduces the need for complex sealing systems or membranes.
Environmentally Safe: Made from non-toxic materials that dont harm the environment.
Prevents Structural Damage: Keeps moisture out, preventing rust, corrosion, and mold that could damage structures.
Custom Lengths: Available in custom lengths to suit various project sizes.
Material Variants: Can be made from different grades of water-swellable material for varying water pressure and environmental conditions.
Different Sizes: Customizable to different thicknesses and lengths to fit specific joint or gap dimensions.
Easy Application: The bar is typically applied by placing it along the joint, embedding it within the concrete, or applying it to the surface before the final layer of concrete is poured.
No Additional Curing Needed: Once the bar is in place and exposed to water, it begins to swell and form a tight seal.
