SikaProof®-808

Pre-applied fully bonded TPO sheet membrane for basement waterproofing

SikaProof®-808 is a TPO based sheet membrane for below ground waterproofing of reinforced concrete structures. It is loosely laid onto prepared substrates below the base slab before fixing reinforcement and casting concrete. A special hybrid bonding layer on the membrane forms a permanent bond with the fresh concrete and prevents lateral water migration between the membrane and the concrete structure.
Overlap joints are sealed using cold-applied tapes or by thermal jointing. The total thickness is 1mm. 

  • Pre-applied: Fixed before placing reinforcement and casting concrete
  • A+Technology: Integral functional layer for chemical and mechanical bond with concrete structure
  • High flexibility and crack-bridging capabilities
  • No lateral water migration between concrete structure and membrane system
  • Easy to install with fully adhered joints
  • Overlap joints are sealed using thermal jointing or cold-applied tapes
