SikaProof®-612

Pre-applied fully bonded waterproofing membrane for basement and foundations

SikaProof®-612 is a fully bonded, pre-applied sheet membrane waterproofing system for basement and foundation structures. It is two-layer composite membrane combined with existing single sheet layer (TPO polymer layer) and functional layer. SikaProof®-612 creates a mechanical bond to concrete, which prevent any lateral water migration.

  • Pre-applied: Fixed before placing reinforcement and casting concrete
  • Strong bonding with concrete
  • No lateral water underflow or migration between the concrete structure and the membrane system
  • Optimized workability
  • Optimized flexibility, tensile strength and multi-axial elongation
  • Flexible with crack bridging abilities
  • Dimensional stability
  • Excellent structural movement properties
