• Pre-applied, before the reinforcement is fixed and the concrete is poured
  • Fully and mechanically bonded to the reinforced con-crete structure
  • No lateral water underflow between the concrete structure and the membrane system
  • High watertightness tested according to various standards
  • Easy to install with fully adhered joints (no welding required)
  • Cold-applied (no pre-heating or open flames)
  • Temporarily resistant to weathering and UV-light during construction
  • Resistant to aging

SikaProof® A-05 is a fully bonded, composite sheet membrane waterproofing system for reinforced concrete structures. It consists of an embossed polyolefin (FPO) based membrane laminated with a unique sealant and a non-woven fleece with a self-adhesive strip on the longitudinal side for the overlap. SikaProof® A-05 is cold-applied and pre-applied, as it is installed without heat or open-flames, and before the steel reinforcement is fixed and the concrete is poured.
