European Waterproofing Association industry average across 46 plants in 17 countries — not a Bauder or KARAT-specific declaration. Expired 7 July 2026; no successor registered on environdec as of 8 Aug 2026. No figure is recorded: an expired industry average declared per m²·year is a conversation opener, not evidence.
Evidence Gaps
- •The recorded EPD is expired and is retained as historical evidence only.
- •EPD product coverage is not confirmed.
- •No quantified carbon result is recorded.
- •No product-specific circularity or material-health claims are recorded.
Design & Specification Notes
Qualitative notes for early design discussion. Not product-specific EPD evidence, and not a basis for numerical comparison.
