Sikaproof P-1201 is a post-applied sheet membrane system consisting of highly flexible polyolefin membrane (SikaProof P-1200) a two component polyurethane adhesive (SikaProof Adhesive-11 H(horizontal) or SikaProof Adhesive-11V (vertical). This exclusive system build-up creates a full and durable bond when installed onto existing hardened concrete structures, such as horizontal edges, decks and on walls with double-faced formwork. In addition, the adhesive prevents any lateral water migration between the SikaProof P - 1201 membrane system and the existing concrete.


SikaProof® P-1201 system consists of flexible FPO membrane SikaProof P-1200  based on Sikaplan® technology available in thickness 1.2 mm. The SikaProof P-1200 membrane is installed onto the freshly applied SikaProof® Adhesive (H or V) onto the prepared hardened structural concrete substrate.

SikaProof 1201 System
System Components
  • SikaProof® Adhesive 11-H or 11-V, is a two component Polyurethane adhesive that is trowelled on to existing concrete substrate to bond the SikaProof®P-1201. 
  • SikaProof® Ex-Tape-150 is used for sealing joints of membrane overlaps or for detailing. 


Using for sealing joints of membrane overlaps detailing:

  • SikaProof® ExTape-150
  • SikaProof® Adhesive-11H  or 11V
