PVC water stopper are essential construction components used to prevent water leakage in concrete structures. Made from durable polyvinyl chloride (PVC), these flexible strips are embedded in concrete joints to ensure watertightness and safeguard against water ingress in critical areas such as basements, tunnels, water tanks, swimming pools, and retaining walls.
Types of PVC Water Stoppers
PVC water stoppers come in various shapes and sizes to suit specific construction requirements. The main types include:
Dumbbell-shaped Water Stoppers
Commonly used for construction joints.
Simple design provides effective water resistance.
Ribbed Water Stoppers
Incorporate ribs for enhanced anchoring in concrete.
Ideal for expansion and contraction joints.
V-shaped Water Stoppers
Designed to handle high-pressure water flow.
Often used in heavy-duty projects like dams or reservoirs.
Kicker-type Water Stoppers
Positioned at the edge of the concrete slab.
Provides additional security for water-prone areas.
Key Features and Benefits
Flexibility and Durability
PVC material ensures longevity and adaptability to varying temperatures and movements in concrete.
Chemical Resistance
Highly resistant to chemicals, making it suitable for industrial applications.
Ease of Installation
Lightweight and versatile, simplifying the embedding process during construction.
Customizable Sizes and Profiles
Available in a wide range of dimensions to match diverse construction needs.
Applications of PVC Water Stoppers
Tunnels and Subways: Prevent water infiltration in underground structures.
Water Retaining Structures: Used in reservoirs, tanks, and swimming pools to keep them watertight.
Basements and Foundations: Protect against groundwater seepage.
Dams and Hydraulic Structures: Provide an effective barrier in high-pressure environments.
Expansion Joints: Handle joint movements while maintaining watertightness.
Installation Guidelines
Positioning: Ensure the water stopper is placed accurately in the center of the joint.
Securing: Use clamps or wiring to hold the stopper in place during concrete pouring.
Joint Movement Allowance: For expansion joints, leave sufficient room for the water stopper to flex and accommodate structural movements.
Overlap and Welding: Ensure proper overlap at joints and weld sections using a heat welding machine for seamless sealing.
Maintenance and Inspection
Regularly inspect for cracks, cuts, or dislodgement.
Repair damages promptly using PVC-compatible adhesives or welding.
Ensure debris and contaminants do not compromise the water stopper’s effectiveness.
Conclusion
PVC water stoppers are a critical element in waterproofing concrete structures. Their versatility, durability, and resistance to harsh conditions make them an indispensable choice in construction projects. By selecting the appropriate type and ensuring proper installation, you can achieve long-lasting protection against water leakage and damage.
PVC Water Stopper IS 15058 Manufacturers
Deesa Flex PVC Water Stopper are flexible Plastic strips which provide a physical barrier to Water at concrete joints, mostly in basements, Water retaining structures like Water tanks, Swimming pools, structural foundations & other below ground level constructions. Water stopper are also termed as Water Bars, seals construction joints. A typical PVC water stopper have two identical half on both sides of a central bulb. These additional extensions are provided with the aim of increasing path length for water entering behind the edge of water Stopper.
