Application

The tape bridges and seals expansion and construction joints, as well as cracks in concrete structures. The maximum permissible expansion under continuous load depends on the thickness of the tape and the width of the non-bonded expansion zone.

Designed to resistant to hydrostatic pressure on the active side. On the passive side a ounterpressure structure.

Description

A thermoplastic elastomer (TPE) sealing tape. Extremely durable, it has excellent resistance to weathering and is UV and chemically stable. The bond to the substrate is achieved using an adhesive.

Features and benefits:

  • Permanent flexible waterproofing seal.
  • Approved for drinking water.
  • High elasticity depending on the thickness of the tape and width of the expansion zone.
  • Thermal welding ensures secure, watertight joints.

Chemical resistance:

  • Good resistance to water-based bituminous coatings, water, cement, lime water and seawater, municipal sewage, ultraviolet (UV) radiation, hydrolysis, microorganisms.
  • Limited resistance to concentrated alkalis/ acids, organic solvents (hydrocarbons, esters, ketone) pH limitations: Depending on the average temperature, the pH-range should be limited as follows: pH = 2 to 10 (< 30°C); pH = 5 to 10 (< 40°C); pH = 6 to 8 (< 60°C).

Applications:

The tape bridges and seals expansion and construction joints, as well as cracks in concrete structures. The maximum permissible expansion under continuous load depends on the thickness of the tape and the width of the non-bonded expansion zone.

Designed to resistant to hydrostatic pressure on the active side. On the passive side a ounterpressure structure.
