Waterproof construction joint reinforcement elements
A rubber sealing tape glued to both sides of the casing stops water effectively.
Features:
- Rubber sealing tape for sealing construction joints in concrete structures.
- The 2 × 20 mm sealing tape is glued to both sides of the construction joint reinforcement element casing.
- The water-absorbent bentonite rubber sealing tape forms a waterproof seam.
- As it absorbs water, the band swells to about twice its original size and fills the gaps in the construction joint as it presses against the structure.
- The sealing tape used is Hydrotite type SS, but other sealing tapes may also be used.
- The sealing tape does not crumble or dissolve, and its highly durable structure withstands even harsh handling.
- Before it has absorbed any water, the sealing tape is thin, so that it stays in place well during the concrete casting.
Other products
We also supply steel loops.
Good to know about our products:
Certified quality:
Kiwa Inspecta has granted Rakennustuote Ristimäki Oy a certificate for construction joint reinforcement elements for joints between concrete structures, according to which our manufacturing meets the quality assurance requirements of standards TR 392:2010 and SFS 1267:2008. Such requirements cannot be met by conventional construction joint reinforcement elements.
Production materials:
Casing made of S280 galvanised steel sheet.
Design and dimensioning:
Designing a customised solution with the customer.
