Water Stopper
A water stopper or water bars also its called as water seals, in this material used in water construction manage water flow and prevent leakage.
Water stopper is a flexible strip made by plastic or rubber that act as a physical barrier to water at concrete joints. its commonly used in both vertical & Horizontal joints, It is commonly used in areas susceptible to water penetration, such as basements, tunnels, water tanks, dams, swimming pools, reservoir and retaining walls.
There are different types water stopper used in construction, which is classified based on their material and application, some of common type of water stopper stated below
- PVC (Polyvinyl Chloride) Water Stoppers
- Bentonite Water Stoppers
- Rubber Water Stoppers
- Metal Water Stoppers
- Hydrophilic Water Stoppers
1.PVC (Polyvinyl Chloride) Water Stoppers
Which is made by PVC – Polyvinyl chloride it has more high flexibility & durability, its mostly used in concrete joints also its good chemical resistance. its widely used in structures like basements, water tanks, and tunnels.
2. Bentonite Water Stoppers
These water stoppers are made from bentonite clay, its is natural, highly absorbent material that swells significantly upon contact with water, The swelling action forms a watertight seal, filling gaps or cracks in concrete joints, in this type of water stopper has self-healing capacity also in this Self-healing capacity; seals cracks and voids by swelling.
3. Rubber Water Stoppers
Rubber water stoppers, also called rubber seals They are typically made from durable rubber materials like neoprene, EPDM (ethylene propylene diene monomer), or silicone, its widely used in structures like pipes, tanks, and joints
4. Metal Water Stoppers
These water stoppers are typically made from durable metals such as steel or copper, these are metallic strips or plates, typically embedded in concrete joints, to block the passage of water and safeguard the structural integrity of the construction. In this type of water stoppers has High strength, long-lasting, also corrosion-resistant
5. Hydrophilic Water Stopper
Hydrophilic Swell able Water stopper  are made of unique sealing compound which expands It is ideal for use in horizontal and vertical construction joints for concrete structures. This type of water stoppers are used in construction, particularly in areas where waterproofing is critical, such as in concrete joints, tunnels, basements, and foundations, in this type of water stopper is easy for installation onto both rough and smooth surfaces.
Advantages of water stopper
Prevents water leakage in reservoirs, dams, swimming pools, and other water-retaining structures.
Ensures water tightness in basements, tunnels, and underground structures, protecting concrete and reinforcement from water damage.
Accommodates structural movements in expansion joints while maintaining a watertight seal
Suitable for a variety of construction projects, including industrial buildings and sensitive installations.
