Fomwork water stoppers (also called water barrier nuts) are used in water retaining structures. It is cast into the concrete wall between two separate tie bars/tie rods. After pouring, tie rods are removed, and the water barrier remains in situ. We can produce the water stopper according to your tie rod thread sizes and specifications.
A formwork tie rod water stopper is a crucial component used in concrete construction to prevent water from penetrating through the tie rod holes in formwork systems. It is particularly important in structures exposed to water or moisture, such as basements, water tanks, retaining walls, and other subgrade or water-retaining structures.
Concrete Formwork Tie Rod System is used with various formwork accessories in concrete construction. This system includes Tie Rods, Formwork Wing Nuts, Concrete Anchor Nuts, Hex Nuts, Connection Nuts, Washer Plates, Formwork Wedge Clamps, Formwork Spring Clamps, Water Stopper/Water Barrier Nuts, Combi Plate Nuts, Plastic Cones, Plastic Tubes, etc.
All of these items are popularly used for concrete formwork & shuttering systems, including wall formwork, column formwork, slab formwork, beam formwork, etc.
Formwork tie rod water stoppers are essential components in concrete construction for structures exposed to water or moisture. They provide an effective and economical solution for preventing water ingress through tie rod holes, ensuring the waterproofing and durability of concrete structures. By maintaining proper installation practices and using high-quality materials, these water stoppers contribute significantly to the long-term performance and integrity of the construction.
**1. Water Sealing:
Primary Function: Provides a watertight seal around the tie rod to prevent water ingress through the formwork.
Effective Barrier: Designed to block water paths effectively, ensuring no leakage through tie rod holes.
**2. Durable Construction:
Material: Often made from high-strength materials such as steel, coated with water-resistant compounds or rubber seals to enhance water-tightness.
Longevity: Resistant to water, chemicals, and physical wear, ensuring durability and long-term performance.
**3. Secure Fastening:
Threaded Design: Provides a secure fit to standard tie rods, ensuring stability and alignment during concrete pouring.
Compatibility: Designed to fit various tie rod sizes and types used in formwork systems.
