Sika® Waterbar is a series of waterstop profiles designed for reliable sealing of construction and expansion joints in concrete structures. They are made from high-quality PVC or TPE materials, which provide effective protection against water penetration under hydrostatic pressure. Embedded in the concrete structure, Sika® Waterbar creates a continuous barrier, preventing leaks and moisture.

Main advantages

• High watertightness
  They create a long-lasting barrier against water, moisture, and aggressive agents in underground and aboveground structures.

• Flexible and durable materials
  PVC or TPE profiles are resistant to various temperature and mechanical impacts, including movements in the structure.

• Easy welding and installation
  The profiles can be heat joined, allowing quick and secure formation of continuous segments.

• Variety of shapes and sizes
  Different types are offered for internal (central) and external (exposed) installation, adapted to various project requirements.

• Long-term security
  Durable under water pressure for years, reducing the risk of repairs and additional costs.

Applications

• Construction joints in concrete
  In foundations, slabs, basements, and walls to ensure waterproof continuity.
• Expansion (deformation) joints
  Allow safe movement of elements in structures such as tunnels, bridges, and underground parking lots.
• Reservoirs, treatment plants, and pools
  Protect against water ingress or leakage of liquids in water-containing and waterproof facilities.
• Underground facilities
  Successfully applied in tunnels and shafts where groundwater penetration is a critical issue.
