SikaProof® P-12

SikaProof® P-12 is a fully and permanently bonded, self-adhesive, post-applied, composite sheet membrane waterproofing system for reinforced concrete structures. It consists of a flexible polyolefin (FPO) based membrane that is pre-coated with an adhesive sealant layer so that the membrane system is self-adhesive. It is cold and post-applied, without heat or open-flames, by a simple peel and stick process on hardened concrete structures.

  • Cold-applied and self-adhesive (no heat or open flames required)
  • Fully and permanently bonded to the reinforced concrete structure
  • No lateral water underflow or migration between the concrete structure and the membrane system
  • High watertightness tested according different standards
  • Easy to install with fully adhered joints (no welding required)
  • Temporarily resistant to weathering and UV-light during construction
  • Resistant to aging
  • Highly flexibile with crack-bridging abilities
  • Resistant to aggressive mediums in natural ground water and soil
  • Can be combined with other approved Sika Waterproofing / Joint Sealing Systems
