A metal/steel waterstopper is a rigid strip made from galvanised or stainless steel, designed to be embedded in concrete joints to prevent water seepage. It provides long-lasting waterproofing protection in critical structures that require durability and resistance to high water pressure. Available in various profiles and thicknesses, steel waterstoppers also contribute to structural stability.
Advantages of Metal Waterstopper:
- Excellent resistance to hydrostatic water pressure
- High durability and long service life compared to PVC or rubber waterstops
- Provides both waterproofing and structural reinforcement
- Suitable for use in aggressive soil and water conditions
- Non-deformable and maintains efficiency under temperature variations
- Available in different grades (galvanized, stainless steel) for specific project needs
Areas of Application
- Basements and foundations
- Retaining walls and tunnels
- Dams, canals, and water reservoirs
- Sewage and treatment plants
- Water tanks and swimming pools
- Expansion and construction joints in concrete structures
