Sikadur Combiflex SG is a high-performance waterproofing system specially designed for sealing various types of joints (working, expansion, and construction), cracks, and openings in building structures. It consists of an elastic Combiflex SG tape and a suitable epoxy adhesive (e.g., Sikadur-31 CF Normal). This combination provides long-lasting protection even under large movements and extreme operating conditions.

Main advantages

• Exceptional flexibility
  The Combiflex SG tape is capable of absorbing large deformations and movements in the structure, making it ideal for expansion and working joints.

• High waterproofing efficiency
  The system is resistant to water, moisture, and a range of chemical influences, including salt solutions, weak acids, and bases.

• Reliable adhesion
  The Sikadur-31 CF Normal epoxy adhesive provides excellent bonding to concrete, metal, and other typical construction substrates, even under wet conditions.

• UV resistance
  The Combiflex SG tape is resistant to ultraviolet radiation, ensuring long-term stability and reliability in outdoor environments.

• Easy application and control
  The system allows for quick and convenient installation, as well as easy inspection during potential repairs or expansions.

Applications

• Expansion joints in buildings and engineering structures
  Frequently used in underground parking lots, bridges, tunnels, and other places with large structural movements.

• Working joints and cracks
  Suitable for new and old concrete structures, ensuring long-lasting waterproofing.

• Openings, pipe penetrations, and details
  The system is used for sealing penetrations in concrete for installations, pipes, and cables to prevent water and moisture ingress.

• Water tanks and pools
  In certain variants (e.g., Sikadur-31 DW), the system is also suitable for contact with drinking water and other water-containing facilities.
