SikaProof® A+ 08

FPO sheet membrane for pre and post-applied fully bonded below ground waterproofing

SikaProof® A+ 08 is a polyolefin (FPO) based sheet membrane for below ground waterproofing of reinforced concrete structures. The membrane can be pre or post-applied. A special hybrid bonding layer on the membrane forms a full and permanent dual bond with the concrete structure. Joints are sealed with cold-applied tapes. The total thickness is 1.35 mm with a membrane thickness of 0.80 mm.

  • Dual bond: full and permanent mechanical and chemical bond with the concrete structure
  • Can be used as a pre and post-applied system
  • No lateral water migration between concrete and membrane
 
  • Fast and easy installation
  • High flexibility and crack-bridging capabilities
  • High watertightness tested according to various standards
  • Good resistance to aggressive conditions in natural ground water and soil
  • Temporarily resistant to weathering and UV exposure
  • Can be combined with other approved Sika® waterproofing and joint sealing systems
