SikaProof? A is an innovative fully bonded sheet membrane system for damp- and waterproofing in basement and below ground structures. Its highly flexible polyolefin membrane, with a special sealant grid and nonwoven fleece provide a unique, mechanical bond effect to the concrete structure and prevent any lateral water underflow between the membrane and the concrete.

Life Cycle Assessment (LCA)

To show the environmental benefits from using thermoplastic SikaProof? A System compared to the mainly used competitive bituminous solutions, a Life Cycle Assessment (LCA) for 1 m2 of two waterproofing systems with similar performance was made. The LCA is from cradle to gate, which means it investigates the potential environmental impacts from raw material acquisition and processing to manufacturing of the product.

Cradle-to-grave approach

The SikaProof? A system is cold-applied and pre-applied, as it is installed without heat or open flame.

SikaProof A: Main Benefits

  • Easier and faster application, no need to weld nor heat, no maintenance needs
  • Less materials per m2 and less energy resources: 220 MJ per m2 (net gains)
  • Less materials per m2 and less carbon emissions: 4 kg CO? per m2 (net gains)
